Overexpression of SiICE2 gene reduces plant height and increases yield in cotton (Gossypium hirsutum).

ABSTRACT: Cotton (Gossypium hirsutum) is the predominant global fiber crop and has considerable significance because of its agronomic characteristics. Among these characteristics, plant height plays a vital role in determining harvest index and yield potential. Previous studies have mainly focused on elucidating the mechanisms governing the ICE-CBF-COR cascade to enhance plant resilienceto low temperatures. Although the ICE2 lines did not show cold tolerance, they exhibited dwarfing of the plants and increased yield. This led to the observations of reduced hypocotyl and internode length, increased biomass, higher yield, and shorter fiber length in the ICE2 lines through phenotypic assessment. From the leaf transcriptome analysis, differential expression of the BR synthesis signaling pathway and the
