Abstract:
Today’s fluctuating climate change era, shows sevior effects on crop growth, so there is need to develop climate resilient crop variety. Recent advancements in the area of -omics of crops have facilitated effect on plant response to environmental stresses. As germplasm plateu occur in many crops so there is need to examine genes from wild variety, which are high yielding and resistant to climate change. As global warming occur temperature fluctuation rate is very high. To better adapt genetics and epigenetics transiently or lastingly to stimuli from the surrounding environment, the chromatin states in plant cells vary to allow the cells to fine tune their transcriptional profiles. Through conventional methods of crop growing and improving there is lot of time consuming process. So their is need to Specifically focuses on genes/DNA sequences. This has paved the way to exploitation of epigenetic variation in crop breeding. That helps to develop climate resilient crop varieties. Several marker techniques have been generated in the last decade starting from the first generation molecular marker, RFLP, that was based on DNA-DNA hybridization and later the invention of PCR gave rise to a second generation of faster and less expensive PCR based markers followed by the third generation sequence based makers.
