The GRAS gene family and its roles in pineapple (Ananas comosus L.) developmental regulation and cold tolerance.

ABSTRACT:

Background

Pineapple (Ananas comosus L.) is a major tropical fruit crop with considerable economic importance, and its growth and development are significantly impacted by low temperatures. The plant-specific GRAS gene family plays crucial roles in diverse processes, including flower and fruit development, as well as in stress responses. However, the role of the GRAS family in pineapple has not yet been systematically analyzed.

Results

In this study, 43 AcGRAS genes were identified in the pineapple genome; these genes were distributed unevenly across 19 chromosomes and 6 scaffolds and were designated as AcGRAS01 to AcGRAS43 based on their chromosomal locations. Phylogenetic analysis classified these genes into 14 subfamilies: OS19, HAM-1, HAM-2, SCL4/7, LISCL, SHR, PAT1, DLT
