Genome Wide Identification and Functional Characterization of Strawberry Pectate Lyases Related to Fruit Softening
摘要
Abstract
Pectate lyase is associated with fruit softening.A total of 68 members of the pectin lyase family were identified and their chromosomal locations were mapped in cultivated strawberry(Fragaria × ananassa).Pectate lyase members in Fragaria × ananassa,F.vesca,Malus × domestica,Prunuspersica,Pyrus bretschneideri and Arabidopsis were divided into nine subgroups based on phylogenetic tree analysis.Transcriptome data analysis showed that the expression levels of Fxac_5g17410,Fxac_13g48930 and Fxac_26g11190 gradually increased with the development of 'Akihime' strawberry fruits,while the expression level was very low in 'Hongxing' strawberry with hard fruits.In addition,overexpression of Fxac_13g48930 in 'Hongxing' reduced fruit firmness,suggesting that Fxac_13g48930 may promote softening of strawberry fruits.关键词
