propagation, shoot regeneration, callus induction, and suspension from lamina explants of .

has high ornamental and medicinal value but is endangered, and significant effort is required to preserve this natural resource. In this study, the stem and sterilized leaves of . were used to explore the effects of different plant hormones basic medium type, initial callus quality, initial liquid volume, and ratio of old liquid culture medium to new on stem proliferation, regeneration and callus suspension culture.

Genome-Wide Identification and Expression Profiling of Heat Shock Protein 20 Gene Family in (Hance) Hedl under Abiotic Stress.

Small heat shock proteins (HSP20s) are a significant factor in plant growth and development in response to abiotic stress. In this study, we investigated the role of HSP20s' response to the heat stress of introduced into low-altitude areas. The gene family was identified based on the genome-wide data of , and the expression patterns of tissue specificity and the response to abiotic stresses were evaluated.
