Integrated physiological and transcriptomic analyses reveal that cell wall biosynthesis and expansion play an important role in the regulation of plant height in alfalfa.

ABSTRACT:

Background

Alfalfa (Medicago sativa L.) is a high-quality, high-protein forage, and the improvement and breeding of key traits are important for enhancing the productivity of alfalfa. Plant height is an important trait that affects crop yield, and its regulatory network mechanism has been widely reported in model plants, however, there are fewer studies on the developmental regulatory of plant height in alfalfa.

Results

In this study, we screened tall (WL525HQ) and short (WL343HQ) alfalfa materials through field experiments and analyzed the regulatory mechanism of plant height based on the multidimensional joint analysis of phenotype, cell, physiology, and molecular biology. The results showed that internode length was an important factor determining plant height in alfalfa,
