Fig 6. Differential expression of chickpea homeobox genes under abiotic stress conditions.

(A) Heat-map showing differential expression of chickpea homeobox genes under abiotic stress conditions in root and shoot tissues. The scale at the bottom represents log₂ fold change, maximum value is displayed as dark red and minimum value is displayed as light green. Gene IDs are given on right side. (B) Real-time PCR analysis to validate the differential expression of representative chickpea homeobox genes during various abiotic stress conditions. The mRNA levels for each candidate gene were calculated relative to its expression in control root or shoot tissues. DS, desiccation stress; SS, salinity stress; CS, cold stress.
