Genomic Sequence and Structural Diversity in Plants

Synopsis

Plant genomes can tolerate a wide range of variation derived from accumulation of mutations, hybridization, polyploidization, and other mechanisms. It is this diversity that underlies the array of phenotypes observed not only across the Plantae kingdom but also within each species. Characterization of sequence level variation (single nucleotide polymorphisms, insertions/deletions, presence/absence variation, copy number variation, and inversions) allows for the association of specific sequence variants with resulting phenotypes, understanding of genetic pathways, rapid varietal improvement by plant breeders, and continuing insight into basic biological phenomenon. The following essay describes the sequence and structural diversity within plant genomes and the implications and applications of this diversity.

Introduction

The phenotypic diversity exhibited within plant species has been widely documented. It is this diversity that has allowed plants to be used for human and animal c ...
