The transcriptome analysis reveals the regulatory mechanisms of female sterility in Lagerstroemia speciosa 'Zichan'.

ABSTRACT:

Background

Ovule abortion presents a major biological obstacle to hybrid breeding in the genus Lagerstroemia, but its molecular regulatory mechanisms remain inadequately understood. This study investigates the female sterility cultivar Lagerstroemia speciosa 'Zichan', providing a comprehensive analysis of the cytological features and molecular regulatory networks underlying female sterility in L. speciosa 'Zichan' for the first time through paraffin section microscopy and transcriptome profiling.

Results

Morphological analyses indicate that female sterility in L. speciosa 'Zichan' results from abnormal embryo sac development. Post the eight-nucleate stage, the embryo sac exhibits disordered fibrous structures, ultimately shrinking and dissolving. During the tetranuclear embr
