“…The second group of stress-responsive proteins comprises regulatory proteins, i. e. proteins involved during regulation of signal transduction and in stress-responsive gene expression (Tuberosa and Salvi 2006;Valliyodan and Nguen 2006;Jewell et al 2010). Genomics analyses of these proteins revealed various transcription factors (TFs), protein kinases and phosphatases, enzymes involved in metabolism of phospholipids and other signalling molecules, such as calmodulin-binding proteins.…”

“…Genomics analyses of these proteins revealed various transcription factors (TFs), protein kinases and phosphatases, enzymes involved in metabolism of phospholipids and other signalling molecules, such as calmodulin-binding proteins. As drought is perceived by a plant, the expression of numerous regulatory genes is affected and a series of TFs and other proteins are synthesised de novo or their levels are changed (Yamaguchi- Shinozaki and Shinozaki 2006;Cutler et al 2010;Jewell et. al.…”

“…Over the past decade, genetic engineering has been intensively evaluated as a new tool for enhancing abiotic stress tolerance in model and crop plants. Evidence has started to accumulate that genetic engineering can be successfully used to produce plants with improved stress tolerance mechanisms (Tuberosa and Salvi 2006;Umezawa et al 2006;Wan et al 2009;Jewell et al 2010;Yang et al 2010).…”

Drought, heat and other abiotic stresses negatively impact growth, development, yield and seed quality of plants. The perception of stress and later adaptation to it occurs via signal transduction pathways that regulate expression of stress-responsive genes. Products of these genes include proteins that are directly involved in plant protection and those that fulfill regulatory function. The latter group includes transcription factors (TFs) and other transcription-related proteins that are investigated using the tools of forward and reverse genetics. Genomics analyses also revealed the importance of other proteins such as protein kinases and phosphatases, enzymes involved in metabolism of phospholipids, signalling molecules, etc. Once the stress response pathways are described, the role of key players in these pathways can be optimised through allele mining, selection and genetic engineering. These approaches offer alternatives to classical breeding and marker-assisted selection.During plant responses to drought, a set of basic leucine zipper (bZIP), homeodomain-leucine zipper (HD-Zip) and WRKY TFs are transcriptionally or post-translationally activated via abscisic acid (ABA)-dependent signal transduction pathways. Despite a surge of data on the significance of plant bZIP, HD-Zip and WRKY TFs in the regulation of drought responses, the three-dimensional (3D) structures of these classes of TFs have been poorly defined. This structural information can be used for rational design of variant TFs that can help in understanding their oligomerisation and post-translational modification patterns, as well as their abilities to recognise target DNA sequences. In turn, this knowledge would permit the commercial application of genetically engineered TFs in agricultural biotechnology, by expression of TF variants and using the wild-type or modified promoter regions of stress-responsive genes. To this end, the aim of this review is to discuss strategies for improving tolerance of cereals to drought and other environmental stresses using molecular variants of the abiotic stress responsive TFs.M.

“…Gene discovery and functional genomics projects have revealed multitudinous mechanisms and gene families, which confer improved productivity and adaptation to abiotic/ biotic stresses (Jewell et al, 2010). Moreover, the stress related genes from the different sources can be cloned and used for developing transgenic wheat.…”

Several environmental stresses are the major hindrances in achieving the attainable yield in wheat crop. The actual losses due to biotic stresses is estimated in the range of 26-29%, however, abiotic stresses have more adverse effects on crop yield and are responsible for about 70% of yield reduction worldwide. Agrochemicals are widely considered as an effective management strategy for wheat crop diseases and insect pests but they adversely affect the human and animal health due to accumulation of chemical residues in the soil, plant tissues and grains. Hence, there is a need for alternate management strategies to protect crop plants against various stresses. Species of the genus Trichoderma are economically important as biocontrol agents, serving as a potential alternative to agrochemicals for overcoming the biotic and abiotic stresses. The importance of Trichoderma in alleviating the myriad of biotic and abiotic stresses of wheat is discussed in this review article.

Microarray datasets are widely used resources to predict and characterize functional entities of the whole genomics. The study initiated here aims to identify overexpressed stress responsive genes using microarray datasets applying in silico approaches. The target also extended to build a protein-protein interaction model of regulatory genes with their upstream and downstream connection in Arabidopsis thaliana. Four microarray datasets generated treating abiotic stresses like salinity, cold, drought, and abscisic acid (ABA) were chosen. Retrieved datasets were firstly filtered based on their expression comparing to control. Filtered datasets were then used to create an expression hub. Extensive literature mining helped to identify the regulatory molecules from the expression hub. The study brought out 42 genes/TF/enzymes as the role player during abiotic stress response. Further bioinformatics study and also literature mining revealed that thirty genes from those forty-two were highly correlated in all four datasets and only eight from those thirty genes were determined as highly responsive to the above abiotic stresses. Later their protein-protein interaction (PPI), conserved sequences, protein domains, and GO biasness were studied. Some web based tools and software like String database, Gene Ontology, InterProScan, NCBI BLASTn suite, etc. helped to extend the study arena.
