| 1 | ChMYB1-ChbHLH42-ChTTG1 module regulates abscisic acidinduced anthocyanin biosynthesis in Cerasus humilis显示文摘Cerasus humilis is a kind of economic fruit tree peculiar to China,which is widely used in the food,landscape,and pharmaceutical industries.Anthocyanins are a phenolic metabolite that plays an essential role in fruit coloration.However,the regulatory network of C.humilis in anthocyanin biosynthesis is still unclear.In this study,the R2R3-MYB transcription factor ChMYB1 was isolated from the full genome of the species.Yeast one-hybrid,dual-luciferase assays,and GUS staining showed that ChMYB1 significantly increased anthocyanin contents in C.humilis fruit by promoting the expression of ChCHS and ChUFGT by binding MBS(MYB-binding elements).ChMYB1 interacted with ChbHLH42and ChTTG1 to form the MBW complex and further enhanced the expression of ChUFGT.In addition,abscisic acid(ABA)treatment promoted the expression of ChMYB1 and anthocyanin accumulation in C.humilis fruit.Interestingly,ABA treatment enhanced the interaction between ChMYB1 and ChbHLH42.Furthermore,ChABI5 inhibited the interaction between ChMYB1 and ChbHLH42.Our data elucidated the primary molecular mechanism of anthocyanin biosynthesis in C.humilis fruit,deepening the understanding of the regulatory network affecting anthocyanin metabolism in edible fruit crops. | Xiaolong Ji Zhe Li Mingyu Zhang Shaoyu Lang Xingshun Song | 2024 | Horticultural Plant Journal2024，10，1： | 0 |
| 2 | CsABF3-activated CsSUT1 pathway is implicated in pre-harvest water deficit inducing sucrose accumulation in citrus fruit显示文摘Pre-harvest water deficit(PHWD)plays an important role in sugar accumulation of citrus fruit.However,the mechanism is not known well.Here,it was confirmed that PHWD promoted sucrose accumulation of citrus fruit,but had limited effect on fructose,glucose and total acid.A sucrose transporter,Cs SUT1,which localizes to the plasma membrane,was demonstrated to function in sucrose transport induced by PHWD.Compared to wild-type,Cs SUT1 overexpression in citrus calli stimulated sucrose,fructose and glucose accumulation,while its silencing in juice sacs reduced sucrose accumulation.Increased sugar accumulation in transgenic lines enhanced plant drought tolerance,and resulted in decreased electrolyte leakage,malondialdehyde and hydrogen peroxide contents,as well as increased superoxide dismutase activity and proline contents.An abscisic acid(ABA)-responsive transcription factor,Cs ABF3,was found with a same expression pattern with Cs SUT1 under PHWD.Yeast one-hybrid,electrophoretic mobility shift assay and dual-luciferase assays all revealed that Cs ABF3 directly bound with the Cs SUT1 promoter by ABA responsive elements.When Cs ABF3 was overexpressed in citrus calli,the sucrose,fructose and glucose concentration increased correspondingly.Further,transgenic studies demonstrated that Cs ABF3 could affect sucrose accumulation by regulating Cs SUT1.Overall,this study revealed a regulation of Cs ABF3 promoting Cs SUT1 expression and sucrose accumulation in response to PHWD.Our results provide a detail insight into the quality formation of citrus fruit. | Xiaochuan Ma Yuanyuan Chang Feifei Li Junfeng Yang Li Ye Tie Zhou Yan Jin Ling Sheng Xiaopeng Lu | 2024 | Horticultural Plant Journal2024，10，1： | 0 |
