“…Loquat belongs to a non-climacteric fruit and has ethylene production at a low level during postharvest storage (Blumenfeld, 1980). The respiration and ethylene production gradually declined after harvest, which can be dramatically suppressed at low temperature (Ding et al., 1998a; Alos et al., 2017). Ethylene has been shown to play vital roles in regulating climacteric fruit ripening via ethylene biosynthesis and signaling (Liu et al., 2015a).…”

“…Wang et al. (2009) showed that the transcript abundance of the genes involved in ethylene signaling decreased during fruit ripening, but ethylene treatment could strongly induce ethylene response sensor 1a ( EjERS1a ), ethylene response sensor 1a ( EjERS1b ), constitutive triple response 1 ( EjCTR1 ), and ethylene response factor 3 ( EjERF3 ) expression in “Luoyangqing.” Alos et al. (2017) found that the transcript levels of 1-aminoacyclopropane 1-carboxylate synthase 1 ( EjACS1 ), 1-aminoacyclopropane 1-carboxylate oxidase 1 ( EjACO1 ), EjCTR1 , and ethylene-insensitive 3-like 1 ( EjEIL1 ) were significantly increased during storage periods, and exogenous ethylene treatment did not affect the expression of these genes involved in ethylene biosynthesis and signaling, whereas 1-MCP significantly inhibited the expression of EjACS1 , EjACO1 , EjACO2 , EjERS1a , and EjCTR1.…”

“…Loquat fruit is classified as non-climacteric fruit, since there is no sudden rise in respiration rate and ethylene production during fruit ripening (Alos et al., 2017). Loquat fruit requires 4–5 months from blossom to fully ripe, which could be divided into five stages: immature green (IMG), mature green (MG), breaker (Br), orange (Or), and fully ripe (FR) (Figure 1), with reference to fruit development and ripening process in the model species, Solanum lycopersicum .…”

Loquat is an important fruit widely cultivated worldwide with high commercial value. During loquat fruit development, ripening, and storage, many important metabolites undergo dramatic changes, resulting in accumulation of a diverse mixture of nutrients. Given the value of loquat fruit, significant progresses have been achieved in understanding the metabolic changes during fruit ripening and storage, as well as postharvest technologies applied in loquat fruit in recent years. The objective of the present review is to summarize currently available knowledge and provide new references for improving loquat fruit quality.

“…A study by Giuseppe Ferrara [20] demonstrated that exogenous ethephon promoted the coloration of grape fruit, but affected the intrinsic quality of the fruit less. E. Alos [21] also found that the application of exogenous ethylene up-regulated the transcriptional levels of ACO1, ACO2, and ACS1 in the ethylene synthesis pathway, and the transcription of ethylene sensing and signaling genes ethylene receptor gene (ERS1a, ERS1b), and CONSTITUTIVE TRIPLERESPONSE 1 (CTR1) through treated loquat fruit. Yin [22] used exogenous ethylene to treat green peel citrus after 150 days of flowering, and found that exogenous ethylene accelerated the degradation of chlorophyll in citrus peel, and led to the expression of chlorophyll degradation-related structural genes.…”

The formation of grape quality and the mechanism of resistance against foreign pathogens affect the storage stability of fruits during post-harvest handling. Ethylene plays a crucial role in regulating the ripeness of fruits and can be used as an exogenous regulator to resist exogenous pathogens. In this study, we used different concentrations of ethephon for treatment of grape fruits before veraison, analyzed the anthocyanin content, soluble solids, titratable acid, and determined fruit firmness and cell wall metabolism-related enzymes during fruit development. Results showed that exogenous ethephon promoted the early coloration of grape fruits and increased the coloring-related genes myeloblastosis A1(MYBA1), myeloblastosis A2(MYBA2), chalcone isomerase (CHI), flavanone 3-hydroxylase (F3H), flavonoid 3’-hydroxylase gene (F3’H), flavonoid 3’, 5’hydroxylase (F3’5’H), 3-O-flavonoid glucosyltransferase (UFGT), and glutathione S-transferase (GST), softening related genes Polygalacturonase(PG), pectinate lyases(PL) and Pectin methylesterase( PME, as well as ethylene metabolism pathway-related genes 1-aminocyclopropane-1-carboxylic acid synthase 1(ACS1), 1-aminocyclopropane-1-carboxylic acid oxidase 2 (ACO2), ethylene receptor gene(ETR2), and ethylene-insensitive 3 (EIN3). Ethephon treatment also increased soluble solids and decreased titratable acid in grape fruit. Fruits pretreated with ethephon were inoculated with Botrytis cinerea, which led to resistance in grape fruit through activation of the antioxidant system. The expression levels of disease resistance-related genes including VvPAD4, VvPIP1, VvNAC26, VvDREB, VvAPX, Vvpgip, VvWRKY70, VvMYC2, VvNPR1 also increased in inoculated fruit with pathogen following ethephon pretreatment. Furthermore, we monitored ethylene response factor 1(ERF1) transcription factor, which could interact with protein EIN3 during ethylene signal transduction and mediate fruit resistance against B. cinerea infection. Meanwhile, overexpression of VvERF1 vectorin strawberry fruits reduced the susceptibility to B. cinerea infection. We suggest that ethylene can induce resistance in ripened fruits after B. cinerea infection and provide adequate postharvest care.

“…; Kays and Paull, 2004 ; Paul et al, 2012 ; Seymour et al, 2013 ). In these fruits, ethylene may not serve as the primary regulator but its production, sensing and signaling may yet be important in regulating specific aspects of ripening ( Chervin et al, 2004 ; Trainotti et al, 2005 ; Alos et al, 2017 ). Other phytohormones such as abscisic acid (ABA) and auxin are proposed to play primary roles in regulating the progression of non-climacteric fruit ripening ( Given et al, 1988 ; Moya-León et al, 2019 ; Fenn and Giovannoni, 2021 ).…”

Atypical Climacteric and Functional Ethylene Metabolism and Signaling During Fruit Ripening in Blueberry (Vaccinium sp.)

Climacteric fruits display an increase in respiration and ethylene production during the onset of ripening, while such changes are minimal in non-climacteric fruits. Ethylene is a primary regulator of ripening in climacteric fruits. The ripening behavior and role of ethylene in blueberry (Vaccinium sp.) ripening is controversial. This work aimed to clarify the fruit ripening behavior and the associated role of ethylene in blueberry. Southern highbush (Vaccinium corymbosum hybrids) and rabbiteye (Vaccinium ashei) blueberry displayed an increase in the rate of respiration and ethylene evolution, both reaching a maxima around the Pink and Ripe stages of fruit development, consistent with climacteric fruit ripening behavior. Increase in ethylene evolution was associated with increases in transcript abundance of its biosynthesis genes, AMINOCYCLOPROPANE CARBOXYLATE (ACC) SYNTHASE1 (ACS1) and ACC OXIDASE2 (ACO2), implicating them in developmental ethylene production during ripening. Blueberry fruit did not display autocatalytic system 2 ethylene during ripening as ACS transcript abundance and ACC concentration were not enhanced upon treatment with an ethylene-releasing compound (ethephon). However, ACO transcript abundance was enhanced in response to ethephon, suggesting that ACO was not rate-limiting. Transcript abundance of multiple genes associated with ethylene signal transduction was upregulated concomitant with developmental increase in ethylene evolution, and in response to exogenous ethylene. As these changes require ethylene signal transduction, fruit ripening in blueberry appears to involve functional ethylene signaling. Together, these data indicate that blueberry fruit display atypical climacteric ripening, characterized by a respiratory climacteric, developmentally regulated but non-autocatalytic increase in ethylene evolution, and functional ethylene signaling.
