In silico Analysis of whole-Genome of Solanum lycopersicum for Alpha-Crystallin Domains Associated with Heat Stress Tolerance

Living organisms alter their gene-expression patterns to withstand stressful conditions. Drought, salinity, heat and chilling are potent abiotic stresses causing an alteration in gene expression. Among these, high temperature stress stimulates Heat Shock Transcription Factors (HSF) which activate he...
