Most longan ( Dimocarpus longan Lour.) varieties have a yellowish-brown or grayish-yellow pericarp, and the discovery of red pericarp (RP) longan expanded the color varieties of longan fruit. Our previous research showed that the red pericarp of RP fruit was mainly caused by anthocyanin accumulation; however, its underlying regulatory mechanism remains unknown. Herein, DlMYB113, an R2R3-MYB transcription factor, was discovered by examining differentially expressed genes in two longan cultivars. Dimocarpus longan MYB (v-myb avian myeloblastosis viral) 113 ( DlMYB113 ) expression was significantly higher in the pericarp and leaves of RP longan than in ‘Shixia’ longan. Sequence alignment analysis revealed two amino acid substitutions in the R3 domain between DlMYB113rp in RP longan and DlMYB113sx in ‘Shixia’ longan. Transient expression of DlMYB113rp significantly increased anthocyanin accumulation in tobacco leaves, whereas DlMYB113sx had negligible effect. Meanwhile, DlMYB113 overexpression promotes anthocyanin accumulation in Arabidopsis and longan calli. Site-directed mutation detection revealed divergence in DlMYB113 function when the R3 repeat 197-position base T was replaced with G, and the 317- and 318-position AT bases were replaced with GA. Our findings indicate that DlMYB113 can regulate anthocyanin production in RP longan, and three mutations in its nucleic acid sequence lead to anthocyanin accumulation, thereby developing molecular markers associated with the anthocyanin accumulation trait in RP longan. This study will facilitate early screening of longan hybrids with desirable fruit color and be significant for breeding new characteristic varieties.","PeriodicalId":491988,"journal":{"name":"Horticulture Advances","volume":" 13","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135192293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The NAC (NAM, ATAF, and CUC) TF, MaNAC029, positively regulated banana ripening by directly inducing ethylene biosynthesis and transcription of fruit quality-related genes. However, its upstream regulatory mechanism still needs to be clarified. Herein, yeast one-hybrid screening revealed that a SQUAMOSA promoter binding protein-like (SPL) TF, MaSPL16, was a potentially upstream regulator of Musa acuminata N A C ( NAM, ATAF, CUC ) 0 2 9 ( MaNAC029 ). Furthermore, gel mobility shift assay revealed that MaSPL16 can directly bound with the “GTAC” element of the MaNAC029 promoter. The gene expression and promoter activity assays demonstrated that Musa acuminata SPL ( SQUAMOSA promoter binding protein-like ) 16 ( MaSPL16 ) expression was inducible by ethylene and ripening. MaSPL16 was localized to the nucleus, displayed a potenial capacity for transcriptional activation of MaNAC029 . More critically, the transient expression of MaSPL16 in bananas accelerated FR via the upregulation of MaNAC029 and its downstream genes. Collectively, the mechanistic basis of a regulatory cascade involving MaSPL16-MaNAC029 that governed ethylene biosynthesis and fruit quality throughout the entire process of banana fruit ripening was unveiled. These outcomes increase the understanding of the gene-transcriptional regulatory mechanisms in FR. They are envisaged to help devise molecular techniques to regulate maturation and improve future fruit quality.","PeriodicalId":491988,"journal":{"name":"Horticulture Advances","volume":"101 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135390060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study analyzes the differences in leaf transcriptomes and phenotypes of two grape species, ‘Manicure Finger ( Vitis vinifera L.)’ and ‘0940 ( Vitis davidii Foex)’, following inoculation with C. diplodiella . Leaf anatomy and H 2 O 2 content confirm the greater resistance of '0940' to C. diplodiella compared to 'Manicure Finger.' Comparative transcriptome analysis reveals that the defense mechanism of '0940' against C. diplodiella involves sesquiterpenoid and triterpenoid biosynthesis, plant-pathogen interactions, sulfur relay systems, suberin and wax biosynthesis, monoterpenoid biosynthesis, as well as flavonoid and flavonol biosynthesis pathways. Using Weighted Gene Co-expression Network Analysis (WGCNA), we identified three modules highly correlated with C. diplodiella resistance and 125 candidate genes, including resistant genes ( R genes), pattern-recognition receptors ( PRR s), and pathogenesis-related proteins genes ( PR genes), which may play important roles in grape resistance to this disease.","PeriodicalId":491988,"journal":{"name":"Horticulture Advances","volume":"3 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135869259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analysis of the genetic factors and molecular mechanisms associated with the red-leaf phenotype can help breed peach very early maturing peach varieties. This study investigated the mechanisms underlying the red- and green-leaf phenotypes in autumn. Red compounds accumulated in the older but not younger leaves in the extremely early-maturing peach variety, ‘99-30-33’, and the leaves of the medium-maturing variety, ‘Zhongtao5 (CP5)’. Metabolic analysis showed that cyanidin-3- O -glucoside was the most abundant anthocyanin in the red leaves. The segregation of the progenies obtained from crossing revealed that the red leaves are a unique hereditary phenomenon not in line with Mendel’s law. BSA-seq and RNA-seq analyses suggest that PpNAC1 was essential for enhancing anthocyanin biosynthesis and was highly upregulated in red than in green leaves. Similar to PpNAC1 , the anthocyanin activator, PpMYB10.1 , was the only gene highly expressed in red leaves. Moreover, the functional genes involved in anthocyanin biosynthesis, such as Prunus persica Flavonoid 3'-hydroxylase ( PpF3'H ), Prunus persicaDihydroflavonol reductase ( PpDFR ), Prunus persica Leucoantho-cyanidin dioxygenase ( Pp LDOX ), Prunus persica Glutathione S-transferase ( PpGST ), and Prunus persica UDP-glucose , flavonoid-3-O-glucosyltransferase ( PpUFGT ), were upregulated in the older red leaves of 99-30-33 but downregulated in the younger 99-30-33 and green CP5 leaves. Yeast one-hybrid and dual-luciferase assays further confirmed that PpNAC1 , which refers to ' Prunus persica NAC ( NAM、A TAF1/2、CUC1/2 )' bound to the promoter of PpMYB10.1 , PpMYB10.1 stands for ' Prunus persica MYB ( v-myb avian myeloblastosis viral ) 10.1 ' and activated its expression along with those of PpGST and PpUFGT. These results provide insights into the mechanisms responsible for the development of red color in peach leaves in autumn.","PeriodicalId":491988,"journal":{"name":"Horticulture Advances","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136280346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
