چکیده

in this research, we studied polyamines including putrescine (put), spermidine (spd) and spermine (spm) changes in three common bean (phaseolus vulgaris) genotypes, k-s-31167, ge-288 and naz under drought stress. our result showed steadily increase in putrescine (put) and spermine (spm) in all three genotypes.  ge-288 genotype showed decrease and then increasing in spermidine (spd) content but k-s-31167 and naz genotypes showed steadily increasing in spermidine (spd). naz genotype accumulated putrescine more than other polyamines and showed the highest amount of putrescine in compare with other genotypes. k-s-31167 genotype accumulated the highest spermine content in compared with other genotypes. our result showed significant increase in electrolyte leakage (el) in all three genotypes. k-s-31167 as drought tolerant genotype and zaz as drought sensitive genotypes showed the lowest and the highest increase in el, respectively.

Differences in antioxidant, morphological and biochemical responses to drought stress in different cultivars of common bean (Phaseolus vulgaris L.)

Drought stress is the most common environmental stress that can significantly influence crop productivity. In this study, morphological and biochemical properties of 17 genotypes of common bean were evaluated under different levels of drought stress and the most sensitive and tolerant genotypes were identified using multivariate analysis. The results indicated that morphological and biochemical...

Abortive Seed Development in Common Bean (phaseolus Vulgaris L.)

INTRODUCTION Embryo defective mutants in Phaseolus vulgaris obtained by Ethyl methanesulfonate (EMS) induction were studied to determine the structural and molecular basis of seed abortion in this species. In the wild-type, the classical pattern of seed development showed coordinated differentiation of the embryo proper, suspensor, endosperm tissue, and seed coat. On the contrarily, EMS mutant ...

Transcriptome Analysis of Salt Tolerant Common Bean (Phaseolus vulgaris L.) under Saline Conditions

Salinity is one of the important abiotic stress factors that limit crop production. Common bean, Phaseolus vulgaris L., a major protein source in developing countries, is highly affected by soil salinity and the information on genes that play a role in salt tolerance is scarce. We aimed to identify differentially expressed genes (DEGs) and related pathways by comprehensive analysis of transcrip...

Analysis of lipoxygenase mRNA accumulation in the common bean (Phaseolus vulgaris L.) during development and under stress conditions.

Plant lipoxygenases (LOX, EC 1.13.11.12) have been involved in processes such as stress responses and development. The levels of these enzymes and their corresponding mRNAs are modulated during these processes as well as by different effectors such as jasmonic acid (JA), its methyl ester (MeJA) or abscisic acid (ABA). A new lipoxygenase (LOX) cDNA clone, PvLOX2, was isolated from a Phaseolus vu...
