摘要: To explore the sequence and expression characteristics of the ZF-HD (zinc finger homeodomain) family in mango (Mangifera indica), sequence analysis of the ZF-HD family was performed using bioinformatics, and RT-qPCR was used to study the transcription levels of the ZF-HD genes during abiotic and biotic stresses. The results showed that 17 members of ZF-HD genes were identified in the mango genome, and a phylogenetic tree was constructed with 59 members of the ZF-HD transcription factor from Arabidopsis, poplar (Populus euphratica), and rice (Oryza sativa), and divided into five evolutionary branches. Moreover, the MiZHDs were unevenly distributed into four groups, including MIF (MiZHD1, MiZHD11, MiZHD7, MiZHD13), ZHDI (MiZHD3, MiZHD10, MiZHD14), ZHDIII (MiZHD4, MiZHD5, MiZHD9, MiZHD16, MiZHD17), and ZHDIV (MiZHD8, MiZHD2, MiZHD6, MiZHD12, MiZHD15). Interestingly, MIF subfamily members have only one structural domain, and other ZHD subfamilies have two domains. RT-qPCR analysis showed that the relative expression of MiZHD4, MiZHD5, MiZHD6, MiZHD9, MiZHD11, MiZHD13, MiZHD14, MiZHD15, and MiZHD16 was significantly up-regulated at 3 h in response to salt stress. Under drought stress, the relative transcription level of MiZHDs was significantly upregulated at 6 h, except MiZHD12, MiZHD13, MiZHD15, and MiZHD17. During Xanthomonas campestris pv. mangiferaeindicae infection, the expression of MiZHD1 and MiZHD11 were significantly induced at 24, 48, and 72 h post infection (hpi). However, most genes were down-regulated during Colletotrichum gloeosporioides infection, only MiZHD16 was significantly up-regulated during 3-48 hpi. In addition, expression analysis revealed that MiZHD7 and MiZHD8 responsed to salicylic acid treatment. These results broadened our understanding of the biological functions and molecular mechanisms of ZF-HD genes, which will provide a theoretical basis for the functional study of the ZF-HD gene family in mango.
