Assessment of Allelic Variation in Bread Wheat (Triticum aestivum L.) Genotypes by In silico Designed Genomic Marker Targeting the Heat Shock Protein Gene hsp90
摘要
Wheat, an essential crop, experiences detrimental effects of heat stress, causing reduced yield and poor grain quality. The experiment was conducted at Krishi Vigyan Kendra (ICAR-KVK) of Banasthali Vidyapith, Rajasthan, India. Ten wheat genotypes were sown under timely and late- sown conditions to study the effect of terminal heat stress in wheat. This study has designed an In-silico genomic primer for the heat-responsive hsp90 gene and used PCR to test it on different wheat genotypes. The primer’s successful detection of genetic variations between these wheat genotypes paved the way to grow a heat-resistant wheat crop. The hsp90 gene was analyzed, and a marker on chromosome 6D was developed utilizing the Primer 3 In silico tool. Wheat genotypes HD3090, PBW660, CBW38, DBW359, DBW296, HP1209 and PBW590 showed allelic variations with genotypes HI1544, DBW316, and JKW261 aiding in the development of polymorphic markers in wheat.
