This invention belongs to the field of
plant genetic engineering and
crop improvement technology, and specifically discloses a drought-resistant functional
gene for eggplant. SmHDC‑ like And its application in improving
plant drought resistance, the
gene SmHDC‑like The
nucleotide sequence of the
enzyme is shown in SEQ ID NO.1; the
amino acid sequence of its encoded
protein, SmHDC-like, is shown in SEQ ID NO.2. This invention is the first to clone the
histidine decarboxylase
gene SmHDC-like from eggplant and confirm that its expression is induced by
drought stress. Overexpression of the SmHDC-like gene significantly improves the
plant's growth adaptability under
drought stress and effectively alleviates drought-induced
growth inhibition. The gene and its encoded product of this invention can be widely applied to the study of
drought resistance mechanisms in eggplant, marker-assisted breeding of plants, and
genetic engineering breeding, providing important gene resources and theoretical basis for drought-resistant
molecular breeding of eggplant and related crops.
