Identification of the citrus GRF gene family and its expression in fruit peel thickening mediated by gibberellin.

ABSTRACT:

Background

Growth-regulating factors (GRFs) play a crucial role in plant growth and development, particularly in cell division and expansion. Citrus fruit cracking, a prevalent issue, adversely impacts both yield and fruit quality. Gibberellins (GAs) are known to ameliorate citrus fruit cracking by inducing thicker peel formation, which is attributed to cell division and expansion. However, the mechanistic link between gibberellins and citrus peel thickening, and whether this process is mediated by GRF genes regulation, has not been definitively established.

Results

In this study, 8 CsGRFs (Citrus sinensis), 11 CcGRFs (Citrus clementina), and 8 CgGRFs (Citrus grandis) were identified from the citrus genome which divided into six clusters, with the genes of the same cluster s
