Genome-wide analysis of the potato Hsp20 gene family: identification genomic organization and expression profiles in response to heat stress

摘要

BackgroundHeat shock proteins (Hsps) are essential components in plant tolerance mechanism under various abiotic stresses. Hsp20 is the major family of heat shock proteins, but little of Hsp20 family is known in potato (Solanum tuberosum), which is an important vegetable crop that is thermosensitive.
