GDSL in Lilium pumilum (LpGDSL) Confers Saline-Alkali Resistance to the Plant by Enhancing the Lignin Content and Balancing the ROS.

ABSTRACT: In order to explore the response mechanism of Lilium pumilum (L. pumilum) to saline-alkali stress, we successfully cloned LpGDSL (GDSL lipase, Gly-Asp-Ser-Leu) from L. pumilum. The qRT-PCR results indicated that the LpGDSL expression was higher in the leaves of L. pumilum, and the expression of the LpGDSL reached the highest level at 12 h in leaves under 11 mM H₂O₂, 200 mM NaCl, 25 mM Na₂CO₃, and 20 mM NaHCO₃. The bacteriophage overexpressing LpGDSL was more tolerant than the control under different NaHCO₃ contents. Overexpressed and wild-type plants were analyzed for phenotype, chlorophyll content, O₂^- content, H₂O₂ content,
