Mining and Analysis of Trichome Development Genes and Single Nucleotide Polymorphism Identification

Trichomes are hair cells derived from specialized epidermal cells on the surfaces of land plants. These hairs are produced as a result of the outward growth of one or more epidermal cells. However, little is known about trichome genes in many plants species including cotton. This poster will report the following: (1) a list of trichome genes identified from the model plant species, Arabidopsis; (2) homologous trichome gene sequences identified from cotton; and (3) single nucleotide polymorphisms (SNPs) identified in cotton by comparing tetraploid cotton with their diploid progenitors.
