Crop drought stress and resistance

Summary:
Drought is the most critical risk for world food security due to shortage in water resources. Great famines has occurred in the past, water supply is limiting in the world and rapidly increasing world population will demand more stable food supplies. It is difficult to estimate drought severity as it relates on many factors like distribution and occurrence of rainfall, capacity of soil keeping moisture and evaporation interest (Wery et al., 1994).
Molecular mechanism of plant under drought investigated in the past has provided considerable information and studies going on to reveal more details (Hasegawa et al., 2000). Soil water deficit reduces crop yield by mainly three mechanisms: (i) decreased canopy attraction of photosynthetically active radiation, (ii) reduced radiation used efficiency and (iii) reduced harvest index (Earl and Davis, 2003). It is crucial to develop the drought tolerance of crops under the changing conditions. Reference Database: http://solanaceae.plantbiology.msu.edu/index.shtml

Great insight on using RNA seq and Hypothesis testing for Drought resistance analysis
The language was really lucid and the steps were really well explained. One start with this project to understand the application of RNA seq, Hypothesis testing and factor regression analysis, Differential gene expression analysis. It was well explained how they were used to understand the significant genes and their expression across the potato cultivars responsible the difference in drought resistance characters.
