Ecotypic differentiation

Understanding how and why genetic variation is partitioned across geographic space is of fundamental importance to understanding the nature of biological species. How geographical isolation and local adaptation contribute to the formation of ecotypically differentiated groups of plants is just beginning to be understood through population genomic studies. We used whole genome sequencing combined with association study of climate to discover the drivers of differentiation in the perennial C4 grass Panicum hallii.

Histone modifications play a significant role in the regulation of transcription and various biological processes, such as development and regeneration. Though a few genomic (including DNA methylation patterns) and transcriptomic studies are currently available in switchgrass, the genome-wide distribution of histone modifications has not yet been studied to help elucidate gene regulation and its application to switchgrass improvement.

Development of SNPs (Single Nucleotide Polymorphisms) marker is an important step to initiate the molecular breeding and genetic based studies. Identification and validation of polymorphic SNP will be valuable resource for gene tagging through linkage mapping/QTL mapping. In present study, two ecological ecotypes of Arabidopsis thaliana i.e. Col-0 and Don-0 exhibited variation at phenotypic level (leaf, flower, siliques and root related traits) and genotypic level (SNPs). Out of 500 SNPs, total 365 polymorphic SNPs were validated on Sequenome MassARRAY.
