MdCNGC15B, a cyclic nucleotide-gated channel (CNGC) protein, positively regulates the tolerance to drought and salt stress in apple

Key Points

• MdCNGC15B positively influences tolerance to drought stress in apple, enhancing survival rates under arid conditions.
• The study shows a significant increase in stress resistance, with measurable improvements in plant health observed during experiments.
• Assessment using physiological analyses confirmed the role of MdCNGC15B in mediating responses to salt and drought stress in apple cultivars.
• These findings highlight the importance of cyclic nucleotide-gated channels in developing drought-resistant apple varieties, benefiting agricultural sustainability.
