Integrative transcriptome-metabolome dissection of the molecular basis of lodging resistance in oat (Avena sativa L.) basal internodes.

ABSTRACT:

Background

Oat (Avena sativa L.) is an important grain and feed crop, playing a significant role in agricultural production. However, lodging remains a key factor limiting oat yield and quality. Recent advances in molecular biology have shed light on the mechanisms of oat lodging resistance, particularly highlighting the critical role of lignin and cellulose content in stem strength. Nevertheless, the molecular regulatory networks governing lignin and cellulose biosynthesis in the basal second internode remain poorly understood.

Results

In this study, we conducted a comprehensive analysis of phenotypic traits, lignin and cellulose content, and transcriptomic and metabolomic profiles in the basal second internode of two contrasting oat cultivars of lodging-resistant MY1 and l
