Abstract

Background: Cotton is the world's richest source of natural fiber. Meanwhile cotton plant is top ranked stress sensitive plant thereby affecting its yield and fiber quality. But, in climate change scenario, fiber yield and quality are being affected due to environmental stresses, especially heat, drought and salinity. Present study is aimed to identify cotton genotype harboring prominently expressed stress responsive genes.

Methods: Four cotton genotypes (IUB-13, IUB-222, IUB-09 and MM-58) were evaluated under drought and salinity stress for yield traits and expression of different stress responsive genes (GhWRKY3, GhDREB2 and GhRDR6).

Results: Pronounced expression of GhWRKY3, GhDREB2and GhRDR6 was observed in cotton variety IUB-13 in stress condition (drought and salinity) as compared to control followed by IUB-222 which revealed that these genotypes might possess substantial potential to cope with environmental hazards encountered in growing season CONCLUSION: Utilization of cotton genotypes i.e., IUB-13 and IUB-222 in cotton breeding program can be very much fruitful for developing cotton genotypes adoptable to climate change.

棉花逆境响应基因的表达研究。

背景：棉花是世界上最丰富的天然纤维来源。同时，棉花是最易受逆境影响的植物，影响其产量和纤维品质。但是，在气候变化的情况下，纤维的产量和质量受到环境压力的影响，特别是高温、干旱和盐度。本研究旨在鉴定棉花胁迫应答基因显著表达的基因型。方法：测定4个棉花基因型（IUB-13、IUB-222、IUB-09和MM-58）在干旱和盐胁迫下的产量性状及不同胁迫响应基因（GhWRKY3、GhDREB2和GhRDR6）的表达。结果：与IUB-222相比，IUB-13棉花品种在干旱和盐胁迫条件下GhWRKY3、ghdreb2和GhRDR6的表达显著，表明这些基因型可能具有应对生长季节环境危害的巨大潜力。利用IUB-13和IUB-222基因型培育适应气候变化的棉花基因型是十分有益的。
