简介：
Overview
This study investigates the ability of third-stage juveniles of Bursaphelenchus xylophilus to enter a state of cryptobiosis under osmotic regulation using potassium chloride (KCl). By exploring their cold-receptive mechanisms, the research provides insights into how these nematodes survive extreme low-temperature stress.
