Transcriptome analysis of two photo-thermo-sensitive genic male-sterile lines reveal GA-mediated regulatory mechanism for rice panicle exsertion.

ABSTRACT:

Background

Hybrid rice is pivotal for ensuring food security in China, yet challenges persist in its seed production. Sterile lines commonly face issues such as necking, gibberellins (GAs) are key regulators of panicle exsertion in rice, necessitating increased application of GAs during seed production, leading to elevated costs and environmental pollution. The novel photoperiod-thermosensitive genic male sterile line Shuang 1S addresses these limitations through its unique non-necked morphology and has super high yield of seed production.

Results

To elucidate the regulatory pathways governing panicle exsertion and identify novel potential genes, this study assessed endogenous GA levels and performed RNA-seq analysis on two sterile lines, Shuang 1S and Han 2S, which displaye
