Durum wheat time series transcriptome responses to water stress

ABSTRACT: A global, systems-based study of the transcriptome response of three drought resistant durum wheat genotypes to water stress. Two parents of a mapping population (Lahn x Cham 1) and a recombinant inbred line (RIL2219), selected for their drought resistance in multiyear field trials, were subjected to controlled time series water stress and samples taken over a six day period to study flag leaf gene expression in parallel with physiological measurements. The aim was to dissect the responses to water stress in an attempt to identify molecular and physiological properties defining stress resistance and thus to build knowledge to accelerate the breeding effort.

Quantitative proteomic analysis of two different rice varieties reveals that drought tolerance is correlated with reduced abundance of photosynthetic machinery and increased abundance of ClpD1 protease

Project description:Rice is the major staple food for more than half of world's population. As global climate changes, we are observing more floods, droughts and severe heat waves. Two rice cultivars with contrasting genetic backgrounds and levels of tolerance to drought, Nipponbare and IAC1131, were used in this study. Four-week-old seedlings of both cultivars were grown in large soil volumes and then exposed to moderate and extreme drought for 7 days, followed by 3 days of re-watering. Mature leaves were harvested from plants from each treatment for protein extraction and subsequent shotgun proteomic analysis, with validation of selected proteins by western blotting. Gene Ontology (GO) annotations of differentially expressed proteins provide insights into the metabolic pathways that are involved in drought stress resistance. Our data indicate that IAC1131 appears to be better able to cope with stressful conditions by up regulating a suite of stress and defence response related proteins. Nipponbare, in contrast, lacks the range of stress responses shown by the more stress tolerant variety, and responds to drought stress by initiating a partial shutdown of chlorophyll biosynthesis in an apparent attempt to preserve resources.

Proteomes of leaf growing zones in rice genotypes with contrasting drought tolerance

Project description:Plants require a distinctive cohort of enzymes to coordinate division and cell expansion. Proteomic analysis now enables interrogation of immature leaf bases where these processes occur. Hence we investigated proteins in tissues sampled from leaves of a drought-tolerant rice (IAC1131) to provide insights into the effect of soil drying on gene expression when compared with the drought-sensitive Nipponbare. Shoot growth zones were dissected to count dividing cells and extract protein for subsequent Tandem Mass Tags (TMT) quantitative proteomic analysis. Gene Ontology (GO) annotations of differentially expressed proteins provided insights into responses of Nipponbare and IAC1131 to drought. Soil drying did not affect the proportion of mitotic cells in IAC1131. More than 800 proteins across most functional categories were up-regulated in drought (and down-regulated on re-watering) in IAC1131, including those involved in organization of the meristem and subsequent cell formation. On the other hand, the proportion of dividing cells in Nipponbare was severely impaired during drought and fewer than 200 proteins responded in abundance when the growing zones underwent a drying cycle. However, those proteins involved in oxidation state and response to external stimuli were more likely to be upregulated by drought, even in Nipponbare.

Coordinated regulation of photosynthesis in rice increases yield and tolerance to environmental stress.

Project description:Plants capture solar energy and atmospheric carbon dioxide (CO2) through photosynthesis, which is the primary component of crop yield, and needs to be increased considerably to meet the growing global demand for food. Environmental stresses, which are increasing with climate change, adversely affect photosynthetic carbon metabolism (PCM) and limit yield of cereals such as rice (Oryza sativa) that feeds half the world. To study the regulation of photosynthesis, we developed a rice gene regulatory network and identified a transcription factor HYR (HIGHER YIELD RICE) associated to PCM, which on expression in rice enhances photosynthesis under multiple environmental conditions, determining a morpho-physiological program leading to higher grain yield (GY) under normal, drought and high temperature stress conditions. We show HYR is a master regulator, directly activating photosynthesis genes, cascades of transcription factors and other downstream genes involved in PCM and yield stability under drought and high temperature environmental stress conditions. To assess the role of increased HYR expression in rice, whole-genome microarrays were used to generate gene expression profiles of rice cultivar Nipponbare transformed with an overexpression construct of the HYR gene (Loc_Os03g02650) under control of the CaMV 35S promoter, along with control wild-type (WT) lines. Two biological replicate samples each from the HYR and WT-control lines were profiled using rice whole-genome microarrays.

Transcription analysis by RNAseq of adult wheat after inoculation with Puccinia graminis f. sp. tritici

Project description:The RNA sequencing analysis was undertaken to investigate the transcriptomic changes in adult wheat inoculated with Puccinia graminis f. sp. tritici the causal agent of stem rust disease. The project firstly aims to compare gene expression in one susceptible wheat line with two wheat lines exhibiting adult plant resistance to the stem rust. Secondly, the project aims to examine the temporal changes in gene expression in wheat after inoculation. Wheat plants was grown until maturity under greenhouse conditions. Plants were inoculated with Puccinia graminis f. sp. tritici and the flag leaf sheath sampled for RNA sequencing. The project aims to give essential insight into the adult plant resistance response in wheat to Puccinia graminis f. sp. tritici inoculation.

Transcription profiling of wheat response to infection by Fusarium pseudograminearum

Project description:Crown rot of wheat, caused by Fusarium pseudograminearum and other Fusarium species is an important disease globally. To understand the host response to challenge by Fp, we examined gene exression changes in the stem base of the wheat variety Kennedy, following inoculation with macroconidia using the Affymetrix GeneChip Wheat Genome Array. Induced genes included mainly those with defensive functions such as genes encoding anti-microbial proteins as well as oxidative stress-related proteins, signalling molecules, and proteins involved in both primary and secondary metabolism. This study is the first comprehensive analysis of the wheat transcriptome during crown rot infection and provides new insights into the host processes involved in plant defence against this pathogen. Experiment Overall Design: There are six samples, three F. pseudograminearum inoculated samples and three mock inoculated samples. Each sample consists of 2cm of stem base from approximately 20 plants.
