TL;DR
This study identifies and analyzes aquaporin genes in bananas, revealing their roles in fruit development, ripening, and stress response.
Contribution
The first comprehensive identification and analysis of the aquaporin gene family in bananas, linking them to development and stress responses.
Findings
47 aquaporin genes were identified in bananas and grouped into four subfamilies.
Some MaAQP genes are highly expressed during fruit development and ripening.
Certain MaAQP genes are strongly induced under abiotic stress, suggesting roles in stress resistance.
Abstract
Aquaporins (AQPs) function to selectively control the flow of water and other small molecules through biological membranes, playing crucial roles in various biological processes. However, little information is available on the AQP gene family in bananas. In this study, we identified 47 banana AQP genes based on the banana genome sequence. Evolutionary analysis of AQPs from banana, Arabidopsis, poplar, and rice indicated that banana AQPs (MaAQPs) were clustered into four subfamilies. Conserved motif analysis showed that all banana AQPs contained the typical AQP-like or major intrinsic protein (MIP) domain. Gene structure analysis suggested the majority of MaAQPs had two to four introns with a highly specific number and length for each subfamily. Expression analysis of MaAQP genes during fruit development and postharvest ripening showed that some MaAQP genes exhibited high expression…
