Physiological and Molecular Analysis Revealed the Role of Silicon in Modulating Salinity Stress in Mung Bean

Salinity stress acts as a significant deterrent in the course of optimal plant growth and productivity, mung bean, being relay crop cereal cropping system, is severely affected by salinity. Silicon (Si), on other hand, has exhibited promising outcomes with regards to alleviating salinity stress. In order understand critical mechanisms underlying bean (Vigna radiata L.) tolerance towards salt stress, this study examined effects different concentrations antioxidant capacity, proteome level alterations, influence Si-transporter salt-responsive genes. was seen effect gaseous exchange machinery, decrease soluble protein phenolic content NR activity, increase accumulation reactive oxygen species. An efficient regulation stomatal opening upon Si application hints proficient conductance CO2 fixation, resulting photosynthesis leading growth. The showed improved levels supplementation, which indicates an solute transport system from source sink. superoxide radicals surge under treatment, but scavenging radicles noted supplementation. more damaging root notably enhanced Moreover, beneficial role further substantiated there notable leaves roots salinity-stressed plants. Furthermore, stimulated competent ROS reinforcing enzyme well coordinating their isozyme expressed varying band intensities. Similarly, Si-mediated peroxidase activity may reveal changes mechanical characteristics cell wall, are turn associated adaptation. Proteomic investigations revealed upregulation or downregulation several proteins, were thereafter identified LC−MS/MS. About 45 proteins functionally classified into (24%), metabolic process (19%), redox homeostasis (12%), transmembrane (10%), response (7%), transcription (4%). gene expression analysis silicon transporter genes (Lsi1, Lsi2, Lsi3) SOS pathway (SOS1, SOS2, SOS3) indicated mitigating Hence, findings can facilitate profound understanding potential adopted due exogenous during
