Dissertation title: Dissection of drought response in Arabidopsis.

Dissertation abstract:

Plants as sessile organisms are susceptible to many environmental stresses such as drought, and salinity. They have therefore evolved mechanisms to acclimate and tolerate environmental stresses. Knowledge of the molecular aspects of abiotic stress gleaned from extensive studies in Arabidopsis has provided much information on the complex processes underlying plant response to abiotic stresses. Nevertheless, there is a need for integration of the knowledge gained and a systematic molecular genetic dissection of the complex responses to abiotic stress. In this study in Arabidopsis, comparative expression profiling analysis of progressive (pDr) and moderate (mDr) drought treatments revealed common drought responses, as well as treatment specific signatures responses to drought stress. Under prolonged moderate drought plants develop different mechanisms for acclimation: induction of cell wall loosening at early stage, and a change in hormonal balance (ABA: JA) at late stage of moderate drought. Taking a reverse genetics approach, a MYB transcription factor (MYB109) has been identified as a regulator of growth under drought and salt stress. Global expression profiling showed possible mechanisms of how MYB109 modulates growth under drought conditions: as a regulator of RNA processing and splicing and as a negative regulator of jasmonic acid biosynthesis and signaling. A forward genetics screen for drought and salt tolerance of transposon activation tag (ATag) lines led to the discovery of novel genes, which shed light on unexplored areas of abiotic stress biology. Utilizing this strategy, a potential role for cell wall modification and MATE transporters in response to drought and salt stress has been discovered, which needs further analysis to integrate this information on the role of these biological processes in plant stress biology.

Project abstract:

Among the major challenges that facing humanity this century is drought. Drought is water deficit due to global warming and decrease in rainfall. Drought problem has been exacerbating in the Mediterranean region, but it was the worst in Jordan. This is because more than 75% of Jordan’s area is desert. Being number one consumer of freshwater, agriculture was negatively impacted by the prevailing drought conditions. Most commonly consumed crops such as wheat depend completely on rainfall, which is unpredicted source given the increase in temperature and the decrease in rainfall started last decade. In Jordan, most of the lands are cultivated with durum wheat (Triticum durum Desf.) and only small area is cultivated with bread wheat, which requires irrigation. With the dominant drought, the production of durum wheat drastically decreased, and it is not enough to meet the requirements of the population in Jordan. Therefore, it is a priority to find ways to overcome the detrimental effects of drought on the growth and production of crops. Different breeding, genetic and biotechnology approaches have been taken to better our understanding of plant response to drought and to improve plant tolerance to drought. Transgenic approach is an approach by which plant tolerance to drought is enhanced by the overexpression of drought responsive genes. Transcription factors (TFs) are regulatory proteins that regulate the expression of other genes. They are considered as important hubs in the regulation of plant growth, development and the fine tuning of plant response to the surrounding environment. Previous studies on model plants such as Arabidopsis showed the improved drought tolerance of transgenic lines, which overexpress drought responsive TFs. In this study, we are proposing the generation of transgenic durum wheat lines that overexpress drought responsive TFs from the model plant Arabidopsis, as a step for the development of drought tolerant wheat lines.

Project objectives:

  1. Cloning of two drought responsive transcription factors (TFs) (genes from MYB and HB families) from the model plant Arabidopsis thaliana.

  1. Transformation of two Jordanian durum wheat cultivars: ACSAD 65 and Hourani nawawi with the cloned TFs.

  1. Evaluation of the performance of the resulted transgenic lines under drought in laboratory and greenhouse conditions.
