Genome‑wide identifcation and expression analysis of growth-regulating factors under drought in Brassica juncea.

ABSTRACT: Growth-regulating factors (GRFs) are plant-specific transcription factors involved in the regulation of plant growth, development, and abiotic stress processes. However, the function of Brassica juncea (L.) Czern & Coss GRFs remain largely unknown. In this study, 34 BjGRF genes were identified in B. juncea. BjGRF members of the same subfamily were found to share a similar motif composition and gene structure. In total, 663 cis-acting elements were found in the promoter regions of BjGRF genes, which were related to light response, hormone response, environmental stresses, and plant growth/development. Additionally, 48 pairs of segmental duplication genes were identified during gene duplication events, and no tandemly duplicated genes were identified. qRT-PCR analysis showed that the 34 BjGR
