Natural genetic variation for regulation of photosynthesis response to light in Arabidopsis thaliana

Rooyen, Roxanne van (2016), Wageningen University

This thesis aims at identifying the genetic loci that are regulating the (sub-) processes in photosynthetic acclimation to increased irradiance levels, in order to obtain the genetic information useful to breed for photosynthetic performance. It shows different Arabidopsis accessions display different photosynthetic responses to various light environments, well relatable to genetic differences. A candidate gene list for the direct response to increased growth irradiance was revealed after performing genome wide association analysis. By identifying and characterizing genes for which different alleles affect photosynthesis responses, some of the regulatory and physiological processes underlying natural variation for photosynthetic acclimation to a step increase in irradiance could be revealed.

 


Electricity from wetlands: Technology assessment of the tubular Plant Microbial Fuel Celll with an integrated biocathode

Wetser, Koen (2016), Wageningen University

One of the emerging renewable electricity technologies is the plant microbial fuel cell (PMFC) as explained in chapter 1. PMFC generates electricity from the rhizodeposits of living plants. Naturally occurring electrochemically active microorganisms oxidize the rhizodeposits producing electrons at the anode of the PMFC. The electrons flow from the anode, via an external circuit where the electricity is harvested, to the cathode. At the cathode, the electrons reduce oxygen to water. PMFC is based on naturally occurring sustainable and renewable processes without net emissions and competition for arable land or nature. Large scale application of the PMFC is preferred in wetlands because a large waterlogged area is required.
The objective of this thesis is to apply PMFC in wetlands with a sustainable biocathode. First, the biocathode is integrated in a lab scale PMFC. Afterwards, the PMFC is installed in wetlands using an improved tubular design with an integrated biocathode and passive oxygen supply. view dissertation >


Environmental and physiological control of dynamic photosynthesis

Kaiser, Elias (2016), Wageningen University

Irradiance is the main driver of photosynthesis. In natural conditions, irradiance incident on a leaf often fluctuates, due to the movement of leaves, clouds and the sun. These fluctuations force photosynthesis to respond dynamically, however with delays that are subject to rate constants of underlying processes, such as regulation of electron transport, activation states of enzymes in the Calvin cycle, and stomatal conductance (gs). For example, in leaves adapted to low irradiance that are suddenly exposed to high irradiance, photosynthesis increases slowly (within tens of minutes); this process is called photosynthetic induction. Photosynthesis in fluctuating irradiance (dynamic photosynthesis) is limited by several physiological processes, and is further modulated by environmental factors other than irradiance, such as CO2 concentration, air humidity and temperature. Studying dynamic photosynthesis and its environmental and physiological control can help to identify targets for improvements of crop growth, improve the accuracy of mathematical models of photosynthesis, and explore new, dynamic lighting strategies in greenhouses.

In this thesis, the limitations acting on dynamic photosynthesis are explored by reviewing the literature, by experimenting with a suite of environmental factors (CO2 concentration, temperature, air humidity, irradiance intensity and spectrum), genetic diversity in the form of mutants, genetic transformants and ecotypes, and by mathematical modelling. Several genotypes of tomato (Solanum lycopersicum) and the model plant Arabidopsis thaliana, all grown in climate chambers, were used in the experiments. The main findings of the thesis are that a) CO2 concentration and air humidity strongly affect the rate of change of dynamic photosynthesis through a combination of diffusional and biochemical limitations; b) Rubisco activation kinetics are pivotal in controlling rates of photosynthesis increase after a stepwise increase in irradiance, and are further affected by CO2 concentration; c) gs limits photosynthetic induction kinetics in A. thaliana but not in tomato in ambient conditions, and becomes a stronger limitation in low CO2 concentration or air humidity; and d) mesophyll conductance, non-photochemical quenching (NPQ) and sucrose synthesis do not limit dynamic photosynthesis under the conditions used.

Improving radiation use efficiency in greenhouse production systems

Li, T. (2014), Wageningen University
A large increase in agricultural production is needed to feed the increasing world population with their increasing demand per capita. However, growing competition for arable land, water, energy, and the degradation of the environment impose challenges to improve crop production. Hence agricultural production efficiency needs to increase. Greenhouses provide the possibility to create optimal growth conditions for crops, thereby improving production and
product quality. Light is the driving force for plant photosynthesis and in greenhouse horticulture, light is often the most limiting factor for plant growth. Therefore, improving radiation use efficiency (RUE) in greenhouse production systems is imperative in order to improve plant growth and production. The objective of this thesis is to obtain insight in improving RUE in greenhouse production systems through better understanding of crop
physiology. Three aspects related to RUE have been studied in this thesis, 1) improving light distribution in the crop canopy; 2) allowing more light in the greenhouse during summer; and 3) balancing the source and sink strength during plant growth.

Linking leaf initiation to the aerial environment: when air temperature is not the whole story

Savvides, A. (2014), Wageningen University
The initiation of new leaves, which takes place at the shoot apical meristem, is essential for plant growth and development. Leaf initiation rate (LIR) is very sensitive to meristem temperature. However, in practice meristem temperature is hardly ever monitored and air temperature is often used instead. It can be questioned whether relating LIR solely to air temperature is valid. This thesis aims at linking LIR to the aerial environment in two main horticultural crops: tomato and cucumber. It was shown that meristem temperature often differs from air temperature, depending on other environmental factors (e.g. radiation, humidity and wind speed) and species-specific traits. LIR was solely influenced by meristem temperature even when it largely deviated from air temperature. In addition, LIR was reduced at low light levels.  Consequently, air temperature is not the whole story when relating leaf initiation to the environment. view dissertation >

 


QTL-based physiological modelling of leaf photsynthesis and crop productivity of rice (Oryza sativa L.) under well-watered and drought environments.

Gu, J. (2013),Wageningen University
Improving grain yield of rice (Oryza sativa L.) crop for both favourable and stressful environments is the main breeding objective to ensure food security. The objective of this study was to amalgamate crop modelling and genetic analysis, to create knowledge and insight useful in view of this breeding objective.
Photosynthesis is fundamental to biomass production, but the process is very sensitive to abiotic stresses, including drought. Upland rice cv. Haogelao, lowland rice cv. Shennong265, and 94 of their introgression lines (ILs) were studied under drought and well-watered conditions to analyse the genetics of leaf photosynthesis. After correcting for microclimate fluctuations, significant genetic variation was found in this population, and 1-3 quantitative trait loci (QTLs) were detected per photosynthesis-related trait. A major QTL was mapped near marker RM410 on Chromosome 9 and was consistent for phenotyping at flowering and grain filling, under drought and well-watered conditions, and across field and greenhouse experiments. These results suggest that photosynthesis at different phenological stages and under different environmental conditions is, at least to some extent, influenced by the same genetic factors.
To understand the physiological regulation of genetic variation and resulting QTLs for photosynthesis detected in the first study, 13 ILs were carefully selected as representatives of the population, based on the QTLs for leaf photosynthesis. These 13 ILs were studied under moderate drought and well-watered conditions in the experiment where combined gas exchange and chlorophyll fluorescence data were collected to assess CO2 and light response curves. Using these curves, seven parameters of a photosynthesis model were estimated to dissect photosynthesis into stomatal conductance (gs), mesophyll conductance (gm), electron transport capacity (Jmax), and Rubisco carboxylation capacity (Vcmax). Genetic variation in light saturated photosynthesis and the major QTL of photosynthesis on Chromosome 9 were mainly associated with variation in gs and gm. Furthermore, relationships between these parameters and leaf nitrogen or dry matter per unit area were shown valid for variation across genotypes and across water treatments. In view of these results and literature reports, it was argued that variation in photosynthesis due to environmental conditions and to genetic variation shares common physiological mechanisms.
QTL analyses were further extended to other physiological parameters of rice. Molecular marker-based estimates of these traits from estimated additive allele effects were used as input tothe mechanistic crop model GECROS. This marker/QTL-based modelling approach showed the ability of predicting genetic variation of crop performance within ILs for a diverse set of field conditions. This approach also showed the potential of extrapolating to a large population of recombinant inbred lines from the same parents. Most importantly, this model approach may improve the efficiency of marker-assisted selection, as it provides a tool to rank the relative importance of the identified markers in determining final yield under specific environmental conditions.
To examine the extent to which natural genetic variation in photosynthesis can contribute to increasing biomass production and yield of rice, the GECROS crop model was used again to analyse the impact of genetic variation in photosynthesis on crop biomass production. It was shown that in contrast to other studies a genetic variation in photosynthesis of 25% can be scaled up equally to crop level, resulting in an increase in biomass of 22-29% across different locations and years. The difference with earlier studies seems related to the fact that variation in both Rubisco-limited and electron transport-limited photosynthesis were observed in our IL population.
This thesis has contributed to closing the gap between genotype and phenotype by integrating crop physiology and genetics through an innovative QTL/marker-based modelling approach. This approach can contribute to making the use of genomics much more efficient in practical plant breeding.

Design criteria for the Plant-Microbial Fuel Cell : from lab tot application

Helder, M. (2012), Wageningen University.
Due to a growing world population and increasing wealth energy demand is rising. Apart from the general increase in energy demand, a specific and even faster increase in electricity  demand can be seen over the last decades. Electricity generation is mainly dependent on fossil fuels. There are three main problems with fossil fuels: 1) easily accessible fossil fuels arebeing depleted, 2) they are polluting (CO2, NOx emissions) and, 3) they are unevenly distributed over the world, leading to dependence of several countries on sometimes politically unstable regions.
To meet future electricity demand, alternative electricity generating technologies are needed. A new alternative electricity generation technology is the Plant-Microbial Fuel Cell (P-MFC). The P-MFC uses living plants and bacteria to generate electricity. The P-MFC makes use of naturally occurring processes around the roots of plants to directly generate electricity. The plant produces organic matter from sunlight and CO2 via photosynthesis. Up to 70% of this organic matter ends up in the soil as dead root material, lysates, mucilage and exudates. This organic matter can be oxidized by bacteria living at and around the roots, releasing CO2, protons and electrons. Electrons are donated by the bacteria to the anode of a microbial fuel cell. The anode is coupled, via an external load to a cathode. The electrons flow through a wire and external load from anode to cathode. The protons that were released at the anode side travel through a membrane or spacer towards the cathode. At the cathode ideally oxygen is reduced together with protons and electrons to water.
To further understand the underlying processes of the P-MFC and the factors that influence its power output, the objective of this thesis was to determine design criteria for the P-MFC. The first focus of the design criteria was to improve the power output of the P-MFC. The higher the power output of the P-MFC, the larger contributionit could give to renewable electricity generation.The transition of a new electricity generation technology to a commercial technology, however, is dependent on more than just power output. Therefore, we studied a number of additional factors that influence the applicability of the P-MFC.

Modelling and remote sensing of canopy light interception and plant stress in greenhouses

Sarlikioti, V. (2011), Wageningen University
A greenhouse crop can be approached as an open system that can be affected by a number of parameters such as light, climate or nutrient supply. In the last decades efforts have been made to understand the functioning of this system and the interaction between the different parameters. The intensive nature of greenhouse cultivation combined with the economic necessity to enlarge the farm size makes the development of decision support systems (DSS) imperative to help the growers in managing their farms efficiently. The foundation of DSS are plant models and in order to work more efficiently they should be able to receive information in real time from sensors that measure different plant parameters such as light interception, leaf area index and photosynthetic stress in a non-destructive way. In order to develop functional DSS it is imperative to develop accurate models and monitoring techniques applied in the specific greenhouse environment.
The aim of this thesis was to explore different techniques to simulate and monitor light interception and photosynthesis by a greenhouse grown tomato canopy. Since photosynthesis is directly linked to light absorption we opted to develop a three dimensional model that takes into account the explicit plant architecture. Different methodologies to monitor these physiological properties online by means of remote sensing were also explored.

Efficiënter fotosynthese voor voedsel en brandstof

Camissonia brevipesIn het Vakblad Onder Glas van april 2013 stellen René Klein Lankhorst , Ep Heuvelink en Tijs Kierkels dat het mogelijk is om de efficiëntie van fotosynthese in planten met een factor tien te verbeteren. Gemiddelde planten (in de kas) weten niet meer dan 0,5% van de energie uit zonlicht om te zetten in biomassa. Sommige woestijnplanten laten zien dat veel hogere percentages mogelijk zijn. Door genen te detecteren die verantwoordelijk zijn voor een efficiënte fotosynthese kunnen merkers worden ontwikkeld, waar veredelaars mee aan de slag kunnen.

Nog hogere percentages zijn in principe haalbaar met algen (10%) en kunstmatige bladeren (40-50%). Met name met kunstmatige bladeren kun je veel duurzamer brandstof produceren dan met biomassa. Als je biomassa gebruikt voor brandstofproductie heb je een enorm areaal nodig, dat kun je beter benutten voor voedselproductie.

Grip op licht

Door het toelaten van meer natuurlijk licht, minder te belichten, en minder te stoken in de kasteelt kan in potentie veel energie worden bespaard bij minimal een gelijkblijvende productie. Daarom wordt in het kader van de programma’s Biosolar Cells en Kas als Energiebron onderzoek verricht naar het toelaten van natuurlijk diffuus licht bij de teelt van potplanten. Dit project bestaat uit 2 fasen. In de eerste fase is onderzoek gedaan met Anthurium en Bromelia. In de tweede fase wordt het onderzoek voortgezet met Phalaenopsis.

Resultaten
De eerste teelt (vanaf april) met bromelia en anthurium liet spectaculaire teeltverbeteringen zien. De anthuriums waren in 16 weken vermarktbaar terwijl dit in de praktijk 22 weken was. Bovendien waren de planten die met diffuus licht waren behandeld circa 25% zwaarder.

Het rapport ‘Grip op licht’ bij potanthurium en bromelia’ (5,2 Mb) kan hier worden gedownload.
