Ripening in climacteric fruit requires the gaseous phytohormone ethylene. Although ethylene signaling has been well studied, knowledge of transcriptional regulation biosynthesis is still limited. Here we show that an apple (Malus domestica) response factor, MdERF2, negatively affects and ripening by suppressing transcription MdACS1, a gene critical for ripening-related Expression MdERF2 was suppressed during fruit, observed bound to promoter MdACS1 directly its transcription. Moreover,...
The phytohormone ethylene plays an important role in promoting the softening of climacteric fruits, such as apples (Malus domestica); however, aspects underlying regulatory mechanisms are not well understood. In this study, we identified apple MITOGEN-ACTIVATED PROTEIN KINASE 3 (MdMAPK3) positive regulator ethylene-induced fruit during storage. Specifically, show that MdMAPK3 interacts with and phosphorylates transcription factor NAM-ATAF1/2-CUC2 72 (MdNAC72), which functions a...
Ethylene biosynthesis in plants involves different 1-aminocyclopropane-1-carboxylic acid synthase (ACS) genes. The regulation of each ACS gene during fruit development is unclear. Here, we characterized another apple ( Malus×domestica ) gene, MdACS6 . transcript was observed not only fruits but also other tissues. During development, initiated at a much earlier stage, whereas MdACS3a and MdACS1 began to be expressed 35 d before harvest immediateley after harvest, respectively. Moreover, the...
Chlorophyll (Chl) degradation is a natural phenomenon that occurs during ripening in many fleshy fruit species, and also storage. The plant hormone ethylene key factor promoting Chl storage, but the mechanisms involved this induction are largely unknown. In study, an apple (Malus domestica) BEL1-LIKE HOMEODOMAIN transcription 7 (MdBEL7), potentially functioning as transcriptional repressor of catabolic genes (CCGs), including MdCLH, MdPPH2 MdRCCR2, was identified partner ethylene-activated...
Abstract Ethylene biosynthesis in apple (Malus domestica) fruit can be suppressed by calcium ions (Ca2+) during storage; however, the underlying mechanisms are unclear. In this study, we identified transcription factor MCM1-AGAMOUS-DEFICIENS-SRF5 (MdMADS5), which functions as a transcriptional activator of ethylene biosynthesis-related gene 1-AMINOCYCLOPROPANE-1-CARBOXYLIC ACID SYNTHASE1 (MdACS1), partner sensor CALCIUM-DEPENDENT PROTEIN KINASES7 (MdCDPK7). Ca2+ promoted MdCDPK7-mediated...
Abstract The pivotal role of ethylene (ETH) in fruit ripening has been extensively studied; however, the function brassinosteroids (BRs) regulating remains poorly understood. Specifically, mechanism by which BRs interact with ETH to affect kiwifruit (Actinidia deliciosa) is unclear. Our research showed that two genes encoding transcription factors, AdNAC3 and AdMYB19, softening gene AdEXP3 (encoding a cell wall expansion protein, expansin 3) were upregulated downregulated BRs. Furthermore,...
The fruit of Pyrus ussuriensis is typically climacteric. During ripening, the fruits produce a large amount ethylene, and their firmness drops rapidly. Although molecular basis climacteric ripening has been studied in depth, some aspects remain unclear. Here, we compared transcriptomes pre- post-climacteric Chinese pear (P. c.v. Nanguo) using RNA-seq. In total, 3,279 unigenes were differentially expressed between fruits. Differentially genes (DEGs) subjected to Gene Ontology analysis, 31...
Fruit size is an important economic trait that controlled by multiple genes. However, the regulatory mechanism for fruit remains poorly understood. A bud sport variety of “Longfeng” (LF) apple ( Malus domestica ) was identified and named “Grand Longfeng” (GLF). The GLF larger than LF, both varieties are diploid. We found cell in LF. Then, we compared transcriptomes two using RNA-Seq technology. total 1166 differentially expressed genes (DEGs) were detected between LF fruits. KEGG analysis...
Abstract The plant hormone ethylene plays a central role in the ripening of climacteric fruits, such as apple (Malus domestica). Ethylene biosynthesis fruit can be suppressed by calcium ions (Ca2+); however, underlying mechanism is largely unknown. In this study, we identified an APETALA2/ETHYLENE-RESPONSIVE FACTOR (AP2/ERF) transcription factor, MdCYTOKININ RESPONSE FACTOR4 (MdCRF4), which functions transcriptional activator biosynthesis- and signaling-related genes, including...
Apple (Malus domestica) fruit generally undergoes a climacteric. During its ripening process, there is peak in ethylene release and firmness simultaneously decreases. Although more in-depth research into the mechanism of climacteric-type being carried out, some aspects remain unclear. In this study, we compared transcriptomes 0-Pre 15-Post (pre- post-climacteric fruit), 15-MCP [fruit treated with 1-MCP (1-methylcyclopropene)]. Various transcription factors, such as MADS-box, ERF, NAC, Dof...
