“…Furthermore, β-1, 4-mannosyl-glycoprotein-like which is involved in cell wall modification and degradation [39] and cinnamoyl CoA-reductase (CCR), an enzyme that catalyzes key steps in the biosynthesis of lignin, were also upregulated due to ethylene treatment. Consistent with this study, Li et al [40] reported the increase in lignin content during cold storage implying the fact that stimulation of lignin biosynthesis could be due to stresses like low temperature and exogenous application of ethylene.…”

Fruit ripening involves changes in physical, physiological and metabolic activities through the actions of enzymes and regulatory genes. This study was initiated to identify the genes related to the ripening of kiwifruit. Gold ‘Haegeum’ kiwifruit is a yellow-fleshed kiwifruit cultivar usually used for fresh marketing. The fruit is harvested at a physiologically mature but unripe stage for proper storage, marketing distribution and longer shelf life. To identify the differentially expressed genes (DEGs) during ripening, fruit treated with ethylene were compared with control fruit that ripened naturally without ethylene treatment. Firmness, respiration rate, ethylene production rate, total soluble solids (TSS), titratable acidity (TA), brix acid ratio (BAR) and overall acceptability were taken during the study as fruit ripening indicators. Total mRNAs were sequenced by Illumina high-throughput sequencing platform and the transcriptome gene set was constructed by de novo assembly. We identified 99,601 unigenes with an average length of 511.77 bp in transcriptome contigs. A total of 28,582 differentially expressed unigenes were identified in the ethylene treatment vs. control. Of these 28,582 unigenes, 13,361 and 15,221 genes were up- and downregulated, respectively, in the treated fruit. The results also showed that 1682 and 855 genes were up- and downregulated, respectively, more than 2-fold at p < 0.05 in fruit treated with ethylene as compared with the control fruit. Moreover, we identified 75 genes showing significantly different expression; 42 were upregulated, and 33 were downregulated. A possible category of the identified ripening-related genes was also made. The findings of this study will add to the available information on the effect of ethylene treatment on ripening and the related changes of kiwifruit at the genomic level, and it could assist the further study of genes related to ripening for kiwifruit breeding and improvement.

“…On agreement with other reports in bamboo shoot (Luo et al, 2007(Luo et al, , 2008Song et al, 2010) and common bean (Dai et al, 2010;Wang et al, 2013), our result showed that Rosa sterilis D. shi fruits treated with 1.0 μL L -1 1-MCP effectively inhibited the transportation of reducing sugar and the increase of cellulose during storage. 1-MCP treatment can effectively inhibit the expression of ethylene synthesis and action including ACD, ACS, ETR, CTR, EON, and EOL1, and suppress respiration and ethylene production rates (Yang et al, 2013;Escribano et al, 2017;Li et al, 2017;Mata et al, 2018;Thongkum et al, 2018). Dur research revealed that postharvest 1-MCP treatment suppressed the respiration rate, ethylene production rate of Rosa sterilis D. shi fruits.…”

“…Dur research revealed that postharvest 1-MCP treatment suppressed the respiration rate, ethylene production rate of Rosa sterilis D. shi fruits. 1-MCP have been confirmed to inhibit the increase of cellulose content in fruit and vegetable, which inhibit the expression of ethylene synthesis and action including Exp, CAD, and glutathione peroxidase gene, reduce the activity of PAL, PPD, CAD, PDD and LAC enzyme, suppress the increase of cellulose content, and thus inhibit the fibrosis of fruits and vegetables (Luo et al, 2007(Luo et al, , 2008Choi & Huber, 2009;Cao et al, 2010;Song et al, 2011;Zhang et al, 2010;Li et al, 2015Li et al, , 2017Tian et al, 2014;Huan et al, 2016;Yihui et al, 2018). Dur data showed 1-MCP markedly accelerated PDD activities, consistent with the report by Li et al (2017), postharvest treatment with 1-MCP suppressed PPD activity in Rosa sterilis D. shi fruits, in contrary with the inhibition of cellulose content during cold storage ( Figure 3A and Figure 4B), consistent with research on Tsai Tai and lettuce leaves with 1-MCP treatment (Zhang et al, 2010;Tian et al, 2014), postharvest 1.0 μL L -1 1-MCP treatment retarded the decrease of ascorbic acid, and maintained the marketable fruits rate of Rosa sterilis D. shi fruits.…”

“…However, the expression levels of genes positively regulated with lignin content were universally much higher than that of negatively regulated genes, indicating that they are the core genes responsible for lignin synthesis during stone cell formation in pear fruits. Genes and enzymes involved in monolignol biosynthesis have been studied extensively in different pear varieties [1,2,8,21,[60][61] . Therefore roles of these genes during lignin accumulation in pear pulp will not be discussed in detail.…”

Background Korla fragrant pear(P•sinkiangensis Yü)is a famous local variety of Xinjiang China. One difficulty is the high stone cell content of these pears, which causes the formation of rough skins on the fruit. To elucidate the underlying mechanisms of stone cell formation, parallel analyses of the transcriptome and proteome was performed to identify important regulators and pathways involved in stone cell formation.Results Fruit samples were collected at three important time points depending on the stages of stone cell formation (20, 50 and 80 days after flowering). A total of 24268 differentially expressed genes (DEGs) and 1011 differentially accumulated proteins (DAPs) were identified from all the time points. Function analysis of the differential genes/proteins revealed that a set of candidates was associated with stone cell formation. These candidates mainly enriched in pathways involved in lignin biosynthesis, cellulose and xylan biosynthesis, S-adenosylmethionine (SAM) metabolic process, Reactive oxygen species (ROS) production, and cell death. We mined a total of 253 DEGs, and 100 DAPs, 63 of which were significantly changed at both the transcript and protein levels during fruit development.Conclusions Our findings reveal that some intriguing genes/proteins were previously unrecognized related with the sclereid formation, which provided new insights into molecular processes regulating sclereid accumulation in pear pulp.
