I started my research projects at Tissue culture and gene transformation section of ABRII by a project about gene transformation of chickpea to resistance pod borer. After that I shifted to Physiology section because of my interests and continued my research on crop Physiology and proteomics category such as gene detection responsible in rice under salt stress and drought stress in wheat. Now, I work on some projects linked to other sections in physiology mandate such as” Evaluation of PGPR bacteria effects on summer crops”, “Propagation and dormancy breaking to produce commercial corms” and “Detection of GM drought tolerant rice based on morphological-physiological and molecular investigation” .

Proteome analysis of rice root under salinity stress

Salinity is a limiting factor affecting crop growth. We evaluated the responses of a salt-tolerant recombinant inbred rice (Oryza sativa L.) line, FL478, and the salt-sensitive IR29. Seedlings were exposed to salt stress and the growth rate was monitored to decipher the effect of long-term stress. . Proteomic analysis showed greater downregulation of proteins in IR29. In FL478, superoxide dismutase, ferredoxin thioredoxin reductase, fiber protein and inorganic pyrophosphatase, which may participate in salt tolerance, increased in abundance.

Characterization of drought tolerance candidate genes in   wheat seedlings by Proteomics

In the present study, the effects of drought stress and re-watering on the tolerance of 4-day wheat seedlings and the role of seed will be investigated by physiology, proteomics and gene expression.The results of drought tolerance showed that four-day wheat seedling had the most tolerance to serious drought stress. Proteomics results showed that most of identified proteins such as Calvin circle, energy reproducing, photosynthetic and anti oxidant enzymes down regulated during drought stress and most of them retrieve to normal or up regulated after rewatering. Also, some identical proteins showed opposite expression because wheat is hexaploid.

Evaluation of growth promoting bacteria effects on growth and yield of greenhouse cucumber, tomato and Bell pepper

The project will be start to find the most useful PGPR bacteria for cucumber,tomato and bell pepper at greenhouse. The selected bacteria from previous project were candidated for each mentioned plants at green house in vegetative periods based important factors in bacteria efficiency. Then they will confirmed under different fertilizers (N,P and K) at productive  periods. The investigation of mentioned effects on physiologic characters related to growth and their mechanism to effect on the summer plants will be done.
