LARP6C orchestrates posttranscriptional reprogramming of gene expression during hydration to promote pollen tube guidance
LARP6C gene expression posttranscriptional regulation pollination fertilization
2023/12/1
Increasing evidence suggests that posttranscriptional regulation is a key player in the transition between mature pollen and the progamic phase (from pollination to fertilization). Nonetheless, the ac...
