Isolation of Brassica napus MYC2 gene and analysis of its expression in response to water deficit stress

Manipulation of stress related transcription factors to improve plant stress tolerance is a major goal of current biotechnology researches. MYC2 gene encodes a key stress-related transcription factor involved in Jasmonate (JA) and abscisic acid (ABA) signaling pathways in Arabidopsis. Brassica napus, as a globally important oilseed crop, is a close relative of Arabidopsis.  In the present study...

Identification and evaluation of HvPIP1; 4 and HvnsLTP genes expression for drought tolerance in barley

It is of great significance to understand the tolerance mechanisms by which plants deal with drought stress and application of these mechanisms for improvement of genotypes in response to drought stress. In order to identify and investigate the expression of genes involved in tolerance to drought stress, leaf and root EST were analyzed in Spontaneum (wild barley) and Nimruz (tolernt to drought ...

Association between aflatoxin contamination and N2 fixation in peanut under drought conditions

Traits related to nitrogen fixation may be used as indirect selection criteria foraflatoxin resistance in peanut. The aim of this study was to investigate therelationship between N2 fixation traits and aflatoxin contamination in peanut underdifferent drought conditions. Eleven peanut genotypes were evaluated under threewater regimes for two seasons in the field. Data were observed on kernel inf...

Differential expression of BnSRK2D gene in two Brassica napus cultivars under water deficit stress

The sucrose non-fermenting 1-related protein kinase 2 (SnRK2) family members are plant unique serine/threonine kinases which play a key role in cellular signaling in response to abiotic stresses. The three SnRK2 members including SRK2D, SRK2I and SRK2E are known to phosphorylate major abscisic acid (ABA) responsive transcription factors, ABF2 and ABF4, involved in an ABA-dependent stress signal...

Differential Expression of Arabidopsis thaliana Acid Phosphatases in Response to Abiotic Stresses

The objective of this research is to identify Arabidopsis thaliana genes encoding acid phosphatases induced by phosphate starvation. Multiple alignments of eukaryotic acid phosphatase amino acid sequences led to the classification of these proteins into four groups including purple acid phosphatases (PAPs). Specific primers were degenerated and designed based on conserved sequences of PAPs isol...
