摘要
YABBY is a specific transcription factor gene family in plants. It has the typical N-terminal C2C2-type zinc-finger domain and the C-terminal YABBY conservative structure domain, which play an important role in the development of the leaves and floral organs. The YABBY gene family directs leaf polarity in mango, playing an important role in maintaining species specificity. In this study, a total of seven YABBY genes were identified in the mango (Mangifera indica) genome. The seven YABBY family members possessed both typical C2C2 and YABBY domains. A phylogenetic tree was constructed based on the amino acid sequences of the 42 YABBY proteins of mango, Arabidopsis, apple, grape, and peach. The phylogenetic tree indicated that the members of the mango YABBY family could be divided into three subfamilies, including CRC, YAB5, and YAB3. Quantitative real-time PCR showed that the transcription levels of the MiYABBYs were significantly different under biotic and abiotic stresses. The transcription level of MiYABBY7 was significantly down-regulated at 0–72 h after Xanthomonas campestris pv. mangiferaeindicae infection, methyl jasmonate and salicylic acid stresses. The MiYABBY1 transcription level was significantly down-regulated at 0–72 h after Colletotrichum gloeosporioides infection. MiYABBYs were expressed specifically in different leaves and fruit, and MiYABBY6 was significantly up-regulated during leaf and fruit development. However, MiYABBY5 showed a contrary transcriptional pattern during leaf and fruit development. This is first report on the mango YABBY gene family at the genome-wide level. These results will be beneficial for understanding the biological functions and molecular mechanisms of YABBY genes.
