“…Kiwifruit ripening is majorly characterized by a decrease in firmness that is due to stimulation of genes encoding several cell wall-modifying enzymes: xyloglucan endotransglycosylase (XET), polygalacturonase (PG), pectate lyase (PL), expansins (EXP), and pectin methyl esterase (PME) among others (Atkinson et al, 2009;Redgwell and Percy, 1992;Wang et al, 2000;Yang et al, 2007). Based on studies on 'Sanuki Gold' kiwifruit, cell wall-modifying genes have been classified as either ethylene-responsive only, low temperature-responsive only, or responsive to both stimuli (Asiche et al, 2018).…”

'Rainbow Red' kiwifruit have been reported to gradually ripen during low temperature storage and on the vine in the absence of detectable ethylene. This study was conducted to compare the expression of ripeningrelated genes during storage at different temperatures and on the vine. Fruit at 5°C and 10°C ripened faster to eating quality within four weeks accompanied with increased expression of ripening-related genes: AcACO3, AcXET2, AcEXP1, AcPG, AcPMEi, AcSUS, AcβAMY1, AcβAMY2, AcGA2ox2, AcNAC3, AcNAC4, and AcMADS2. Fruit at 15°C required a longer period of eight weeks to attain eating quality in concurrence with delayed accumulation of the ripening-related genes. Fruit at 22°C ripened at the slowest rate and did not attain eating quality even after eight weeks, with very minimal accumulation of ripening-related genes. Onvine ripening occurred slowly at the early stages when the average field temperature was ~20°C, but the rate increased as the temperature dropped to ≤15°C accompanied by increased expression of ripening-related genes. These results indicate that both ripening on-vine and during low temperature storage are modulated by low temperature independent of ethylene.

“…Indeed, heterologously expressed XTH genes from this group have all exhibited exclusively XET activity (Supplemental Table S1), although in most cases donor and acceptor substrate specificities have not been extensively analyzed. For XTH phylogenies to have a predictive power, an emerging picture is that finer considerations of clade and subclade groupings should be made, based on both high-level sequence clustering algorithms and rigorous biochemical analysis (Baumann et al, 2007;Atkinson et al, 2009).…”

“…However, the EIN3/EIL gene family is considered to have a role in transcriptional regulation of target genes, such as Arabidopsis ERF1 (Solano et al, 1998) and tobacco basic PR (Hibi et al, 2007). In order to explore the relation between AdEIL genes and kiwifruit ripeningrelated genes, six such genes were selected for promoter isolation: AdACO1 (ACC oxidase, similar to the gene used in the ACO knockout kiwifruit; Xu et al, 1998), AdXET5 (xyloglucan endotransglycosolase; Schrö der et al, 1998;Atkinson et al, 2009), AdEXP1 (Yang et al, 2007), AdPG (the promoter of AdPG was confirmed in tomato; Atkinson and Gardner, 1993), and AdERS1b and AdETR1 (ethylene receptor genes; Yin et al, 2008). All these genes are associated with fruit ripening and softening.…”

Kiwifruit (Actinidia deliciosa) is a climacteric fruit sensitive to low concentrations of ethylene. To investigate the transcriptional mechanisms underlying kiwifruit ethylene response, transcription factors encoding four EIN3-Like (EILs) and 14 Ethylene Response Factors (ERFs) were cloned from kiwifruit. Expression of these transcription factors was examined during fruit development. The expression of transcripts of most AdERFs was higher during early fruit development, with the exception of AdERF3, which increased with maturity. Several AdERFs were apparently down-regulated by ethylene, as they were affected by the ethylene inhibitor 1-methylcyclopropene and by antisense suppression of ACO (for 1-aminocyclopropane-1-carboxylic acid oxidase) in the fruit. In contrast, AdEILs were constitutively expressed during fruit development and ripening. The transcription factors AdEIL2 and AdEIL3 activated transcription of the ripening-related genes AdACO1 and AdXET5 (xyloglucan endotransglycosylase gene) and, when overexpressed in Arabidopsis (Arabidopsis thaliana), stimulated ethylene production. The potential repressor AdERF9 suppressed this promoter activity. These results support a role for kiwifruit EILs and ERFs in transcriptional regulation of ripening-related genes and in the regulation of kiwifruit fruit-ripening processes.
