Main research fields

1. Molecular mechanisms of grass adaptation to nutritents and ionic stresses. We study how grasses perceive and respond to extracellular nutrient status or ionic stresses through signal transduction, transporter regulation and microbe interactions.

2. Grass Cellular Signal Transduction and Development. We focus on phytohormone signal transduction in forage and study their roles in plant development especially under abiotic stresses.

Achievements in scientific research

In recent years, we first found that rhizobial symbiosis regulates arsenic accumulation in Medicago plants through the regulation of nitrate transporter NTR3.1Ls by ABA and linalool (Liaoliao et al., 2021,  Journal of Hazardous Materials ); We revealed the molecular mechanism of vacuolar phosphorus transporters regulating arsenic tolerance and arsenic accumulation in plants (Mingda et al., 2018,  Plant & Cell Physiology ); We creatively proposed the hormonal stress-level-dependent biphasic (SLDB) effects of brassinosteroids on plant salt tolerance and revealed the mechanism via putrescine metabolism (Jinlong et al., 2020,  Plant Cell and Environment ); We found that alfalfa aquaporin MsPIP2;2 participate in the regulation of plant salt tolerance (Shuxia et al., 2019,  Environmental and Experimental Botany ). These studies provide important bases for heavy metal accumulation and genetic improvement of salt stress tolerance in grasses.
