ripening-related genes including genes involved in ethylene synthesis signal transduction and carotenoid biosynthesis Our results provide insight at the whole genome level regarding gene regulation by 1-MCP during fruit ripening Understanding the molecular basis of 1-MCP inhibition on tomato ripening may help farmers and

One step in this process is to isolate appropriate genes To this end we have isolated a collection of cDNA clones that represent genes whose mRNAs are regulated during fruit ripening Ten clones were isolated using RNA from various stages of softening and RNA from phenotypically different fruit through differential screens

Strawberry is a typical nonclimacteric fruit whose ripening mechanism needs to be further investigated Sucrose has been recently proved as a signal molecule participating in strawberry fruit ripening and related processes While in the effects of sucrose application timing and concentration on ripening fruit qualities remain unclear as well as the transcriptome-wide

Jul 16 2015In fruits the expansin gene was similarly expressed in both wild type and transgenic samples (Fig 7d) while in the case of sepals the gene transcripts were almost undetectable in wild type ones and showed a ripening-related increment in the transgenic sepals in parallel with the ripening of the fruit (Fig 7c)

tomato fruit unable to autonomously produce ripening-related ethylene (data not shown) were therefore used to identify genes responsive to either 15min or 5h ethylene treatment (50mll–1) Isolation of early ethylene-regulated cDNA clones by differential display RNA from ethylene-treated and untreated tomatoes was

and LEACO4 ripening-related increases in transcript abundance are largely blocked by 1-MCP treatment indicating that these genes are positively regulated by ethylene The regulation of ACS gene expression during fruit ripening has been investigated using a combination of ethylene and inhibitor studies to-

Dec 27 2019Considering that FaPRE1 is a ripening-related gene its regulation by auxins and ABA was studied It has been previously reported that achenes removal from the surface of immature G3-stage fruits decreases the inner concentration of auxins in the receptacle which induces the transcription of many ripening-related genes [9 19]

For gene expression analysis organs were collected frozen in liquid N 2 and stored at −80C until RNA extraction Three independent samplings were performed for each measurement Tomato fruit nuclei isolation and Western blotting Nuclei were isolated from tomato fruits picked at B + 5 stage and assayed for RIN protein

USA) Gene structure and organization PCR amplifications using degenerate oligonucleotide primers resulted in the isolation of partial cDNAs with the expected sizes for Ps-ETR1 (1737 bp) Ps-ERS1 (1530 bp) Ps-CTR1 (513 bp) and Ps-ERF1 (462 bp) The amplified fragments were cloned into the pGEM-T easy vector and sequenced
