The coconut (Cocos nucifera L.), a valuable tropical crop, is rapidly declining in genetic diversity due to natural disasters, pest and disease attack, land clearing for other crops. Seed banking impractical conservation its large, recalcitrant seed, maintaining field gene bank collections costly vulnerable environmental pressures. Cryopreservation offers promising alternative method conserving diversity, but the success recovering cryopreserved materials remains limited, with few studies consistently reporting high rates of recovery. This highlights need improved cryopreservation protocols, particularly tissue dehydration, which one critical steps process plant A desiccator was developed that enabled rapid embryo dehydration ultra-dry airflow. reduced moisture content 20% (the predetermined viability threshold) within 6 h representing 2-h improvement when compared previous approach, while germination rate (71%). Smaller embryos (500 550 mg fresh weight) desiccated faster than larger (800 900 (30%), making small unsuitable cryopreservation. 5-day sucrose (0.4 M) pre-treatment further time 4 h, (70%).

The genus Camphora encompasses species of significant ecological and economic importance, such as C. parthenoxylon officinarum, which exhibit distinct phenotypic traits stress responses. This study seeks to elucidate the molecular basis cold tolerance through comparative transcriptomic analysis complemented by physiological characterization. RNA sequencing revealed 6123 differentially expressed genes between two species, with enriched pathways related stress, oxidative carotenoid biosynthesis, photosynthesis. Key genes, annexin D5, chlorophyll a/b-binding protein, early light-induced protein 1, 9-cis-epoxycarotenoid dioxygenase, were identified critical regulators frost resistance, photosynthetic efficiency, biosynthesis. Functional enrichment analyses highlighted involvement signal transduction, membrane stabilization, secondary metabolism in adaptive Physiological assays supported these findings, showing higher content enhanced antioxidative enzyme activities parthenoxylon. These results provide valuable insights into genetic biochemical mechanisms underlying adaptation offer promising targets for enhancing resilience economically plants.
