Comparative transcriptome analysis of inbred lines and contrasting hybrids reveals overdominance mediate early biomass vigor in hybrid cotton.

ABSTRACT: BACKGROUND:Heterosis breeding is the most useful method for yield increase around the globe. Heterosis is an intriguing process to develop superior offspring to either parent in the desired character. The biomass vigor produced during seedling emergence stage has a direct influence on yield heterosis in plants. Unfortunately, the genetic basis of early biomass vigor in cotton is poorly understood. RESULTS:Three stable performing F1 hybrids varying in yield heterosis named as high, medium and low hybrids with their inbred parents were used in this study. Phenotypically, these hybrids established noticeable biomass heterosis during the early stage of seedling growth in the field. Transcriptome analysis of root and leaf revealed that hybrids showed many differentially expressed genes (DEGs) r
