Identification and Analysis of GATA-Type Transcription Factors in the FSH Genome of Fusarium solani On Paeonia
Root rot in Paeonia is mainly caused by Fusarium solani,which poses a significant threat to peony-growing areas.GATA transcription factors play a crucial role in colonization and pathogenicity in pathogenic fungi.In the FSH genome of Fusarium solani associated with Paeonia root rot,6 GATA tran-scription factors were identified,all localized in the nucleus.Among these 6 GATA transcription factors,4 are basic proteins(g2237.t1,g4943.t1,g6316.t1,g677.t1),1 is acidic(g3670.t1),and 1 is neutral(g13425.t1).All these proteins are hydrophilic and unstable,with the number of amino acids ranging from 435 to 1025.Conserved domain analysis revealed that these proteins contain the ZnF-GATA domain,with g13425.t1 also encoding two PAC domains,and both g13425.t1 and g3670.t1 containing PAS do-mains.Tertiary structure prediction indicated that none of these proteins have signal peptide sequences.The study explains the genomic GATA transcription factors and their bioinformatics characteristics in Fu-sarium solani associated with Paeonia,providing a theoretical basis for further research on the functional-ity of this class of transcription factors.
