Transcriptomic analysis of Col plants and wrky48 mutants subjected to high light, heat stress and their combination

ABSTRACT: Plants growing in the field are subjected to high light intensities that are often accompanied by high temperatures. In this work, we analyzed transcriptomic responses of wild type Col plants and mutants defective in the transcription factor WRKY48 to understand why wrky48 mutants are more tolerant to the combination of high temperatures and high light stress. Our results indicate that jasmonic acid accumulation induced by the combination of high light and heat stress could repress WRKY48 expression, enabling the expression of acclimation genes to this stress combination.

Acclimation of photosynthesis to changes in the environment results decreases oxidative stress in Arabidopsis thaliana

Project description:Dynamic acclimation of photosynthesis plays an important role in increasing plant fitness under variable light environments. Acclimation is mediated by a glucose-6-phosphate/phosphate translocator, GPT2. This study examined whether plants lacking GPT2, which are defective in acclimation to increases in light, are more susceptible to oxidative stress. To understand this, we used the model plant of Arabidopsis thaliana (accession Wassilewskija-4 (Ws-4)) and compared this to mutants lacking GPT2. Plants were grown at low light (100 μmol m−2 s−1) for 7 weeks. For acclimation experiments, a set of plant from low light was transferred to 400 μmol m−2 s−1 for 7 days. Microarray analysis showed that gpt2 plants showed a greater induction of stress related genes relative to WT.

Co-expression networks of deacclimation-impaired mutants identified involvement of hypoxia and complex regulation of the cold stress release response

Project description:Plants adapt to cold, non-freezing temperatures through cold acclimation and subsequently lose the acquired freezing tolerance in warmer temperatures in a process called deacclimation. By measuring the freezing tolerance of mutant lines, this study identified that the loss of HRA1, LBD41, MBF1c and JUB1 slows the rate of deacclimation in the first four days in Arabidopsis thaliana. Comparative transcriptomic (RNA-Seq) and co-expression analysis of Col-0, mbf1c and jub1 during deacclimation identified an involvement of thermoswitches, cell wall remodeler and transporters in the regulation of the rate of deacclimation. In mbf1c and jub1 a unique increase in stress responsive genes and regulation of the jasmonic acid pathway was detected and linked to the mutants’ retention of freezing tolerance during deacclimation. Hypoxia was observed to be induced in early deacclimation evidenced by an increase in ADH enzyme activity and upregulated gene expression of hypoxia markers (qRT-PCR). This work suggests that the overserved hypoxia response creates hypoxic niches within the plants and supports growth and development during deacclimation.

Janus-faced nature of light in the cold acclimation processes of maize

Project description:Earlier findings indicated that light plays a critical role in the development of frost tolerance in winter cereals. However, the exact mechanism is still poorly understood. In the present work the effects of light during the cold acclimation period were studied in chilling-sensitive maize plants. The results show that although exposure to relatively high light intensities during cold acclimation at 15 °C causes various stress symptoms, it enhances the effectiveness of acclimation to chilling conditions (5 °C in the light). Interestingly, certain stress responses were light-dependent not only in the leaves, but also in the roots. A microarray study was also conducted to achieve a better understanding of the interaction of low temperature and light intensity during the cold hardening period. Numerous genes significantly differentially expressed were observed in almost all assimilation and metabolic pathways. Acclimation at moderately low temperature and low light intensity reduced the level of soluble sugars, while chilling increased it. Greater accumulation during hardening was detected at relatively high light intensity. It seems that the photoinhibition induced by low temperature is a necessary evil for cold acclimation processes in plants.

Proteomic analysis of two citrus rootstocks subjected to multiple abiotic stress conditions

Project description:Drought, heat and high light irradiation are abiotic stresses that negatively affect plant development and reduce crop productivity. The confluence of these three factors is common in nature, causing extreme situations for plants that compromise their viability. Drought and heat stress increase the saturation of the photosystem’s reaction centers, increasing sensitivity to high light irradiation. In addition, these stress conditions affect PSII integrity, alter redox balance of the electron transport chain and decrease photosynthetic rate. Here, we studied the effect of drought, high light and heat stress factorial stress combination on the photosynthetic apparatus of two citrus rootstocks, Carrizo citrange (Citrus sinensis × Poncirus trifoliata) and Cleopatra mandarin (Citrus reshni). Proteomic data, together with transcriptomic, showed the main responses of citrus plant to multiple abitoic stress conditions. The enhancement of KEGG pathways such as RNA metabolic processes and the accumulation of family proteins like HSPs were key responses to face the combination of these abiotic stress factors.

Cold induced changes: differences between the Arabidopsis thaliana wild type and freezing sensitive mutants.

Project description:Arabidopsis sfr mutants are deficient in cold acclimation during exposure to coolnon-freezing temperatures. Although not visibly affected by the cold they have lost the ability to survive subsequent freezing. We plan to investigate how the sfr2 and sfr6 mutants respond to low temperature on the gene expression level. Wild type plants that have undergone identical treatments in parallel are necessary controls. The cold treatment of plants in the rosette stage (soil grown in a 8/16 hours day/night cycle) will be carried out in a cooled growth chamber at 4 degrees for 24 hours (same light regimetreatment starting/ending at the 4th hour of light). The aerial parts of the treated and untreated plants will be collected and frozen immediately in liquid nitrogen for RNA extraction. Comparison of the cold response of thousands of Arabidopsis genes in the wild type to the situation in our freezing sensitive mutants will enhance our understanding of the cold response itself and illuminate the effect of the mutations on the cold acclimation process.

Transcriptomic analysis of tomato plants subjected to multifactorial stress combination

Project description:Climate change and industrial pollution are responsible for major losses in crop yield worldwide. Tomato plants are subjected to multiple stress conditions in combination when growing in the natural field. In this work, we analyzed the transcriptomic response of tomato plants to the combination of salinity and heat stress, when plants were or were not inoculated with the beneficial bacteria Pseudomonas Putida. The results suggest that specific transcripts are regulated only under stress combination in plants inoculated with the bacteria. These transcripts could be related with the enhanced tolerance of inoculated plants under conditions of stress combination.
