Transcriptome-based analysis reveals key molecular mechanisms and functional characterization of MaCAX3 gene involved in manganese stress responses in mulberry plants.

ABSTRACT:

Background

Manganese (Mn) deficiency and toxicity are major constraints on crop production in soil. Plants have evolved cascade strategies and specific mechanisms to tolerate these stresses. Understanding the molecular mechanisms of tolerance to Mn stress is crucial for improving the efficiency of conferring Mn tolerance and phytoremediation, which is intriguing for evolutionary research on plant adaptation to abiotic stresses. In this study, the responses of mulberry to varied concentration levels of Mn (MnSO₄), ranging from deficiency (0 mM and 0.03 mM), sufficiency (0.15 mM), and toxicity regimes (1.5 mM and 3 mM) were compared by elucidating the physiological, transcriptome profiling, and functional characterization of the MaCAX3 gene in mulberry leaves.
