“…This paradoxical phenomenon might be due to the profiles of accumulated flavonoids, which were determined from not only the involvement of key genes in the biosynthesis pathway, such as 4CL, CHS, OMT, FLS and AOMT; but also, from the blocking of the ABA biosynthesis pathway by NDGA. It was reported that the polyphenolic biosynthesis and the internal browning in postharvest pineapple were inhibited by the application of 380 µM ABA, due to the improved activity of antioxidant enzymes [29]. It was notable to mention that both MLT and ABA promoted flavonoid biosynthesis; therefore, is there any possible interaction between the influences resulted from exogenous MLT and ABA?…”

Grape polyphenols contributing to more than half of the global polyphenol market were well studied; however, how melatonin (MLT), a potential plant hormone, and abscisic acid (ABA) affects polyphenols profile is still poorly understood. To explore whether these hormones are involved in polyphenolic biosynthesis, grape (Vitis vinifera cv. Kyoho) was exposed to MLT, ABA, and NDGA (nordihydroguaiaretic acid, an ABA biosynthesis inhibitor) treatments, and 16 polyphenols were identified from grape extracts by high performance liquid chromatography quadrupole time of flight mass spectrometry (HPLC-Q-TOF-MS). Both exogenous MLT and ABA significantly enhanced the biosynthesis of each flavonol and flavanol component, especially catechin, which was almost increased double by 200 µM of MLT treatment. Furthermore, the expression of genes involved in flavonoid biosynthesis, including 4-coumaroyl-CoA synthase, chalcone synthase, flavonoid 3′-hydroxylase, anthocyanin 3′-methyltransferase, flavonol synthase, flavonoid-3-O-glucosyltransferase, and flavonoid 3′,5′-methyltransferase were highly up-regulated as well but were down-regulated by NDGA. The present study provided new insights for improving flavonoids accumulation in agricultural production and its underlying mechanism.

“…China produced approximately 1.89 million tons of pineapple in 2014, accounting for 7.4% of worldwide production (FAO, 2014). Under natural conditions, pineapples undergo internal browning (IB) during postharvest storage (Zhang et al, 2015). Therefore, the quality and storage potential of this fruit must be improved.…”

“…Therefore, the quality and storage potential of this fruit must be improved. Effective methods to delay the development of IB include 1-methylcyclopropene treatment (Selvarajah et al, 2001), controlled atmosphere (Nimitkeatkai et al, 2006), waxing (Hu et al, 2012), and exogenous abscisic acid (Zhang et al, 2015), but the mechanism of the IB remains unclear. The recent completion of the pineapple genome has allowed for the genome-wide identification of a number of important gene families (Ming et al, 2015).…”

Phospholipase D (PLD) in plants plays vital roles in growth, development, and stress responses. However, the precise role of PLDs in pineapple remains poorly understood. In this study, 10 putative PLD genes, designated as AcPLD1–AcPLD10, were identified based on the pineapple genome database. The 10 AcPLDs could be clustered into five of the six known PLD families according to sequence characterization. Their deduced amino acid sequences displayed similarities to PLDs from other plant species. Expression analyses of PLD mRNAs from pineapple pulp were performed. The 10 PLDs exhibited differential expression patterns during storage periods of fruits treated with hexaldehyde (a specific PLD inhibitor) which could alleviate internal browning (IB) of pineapple after harvest. Functional subcellular localization signaling assays of two PLD proteins (AcPLD2 and AcPLD9) were performed by fluorescence microscopy. To further detect the potential action mechanism underlying PLD involved in the IB defense response, PLD, hydrogen peroxide (H2O2) and H2O2 associated with antioxidative enzymes such as superoxide dismutase, catalase, NADPH, and ascorbate peroxidase were quantified by enzyme-linked immunosorbent assay. This report is the first to provide a genome-wide description of the pineapple PLD gene family, and the results should expand knowledge of this family.

“…However, it presents a short postharvest life (Martins et al, 2012). Some efforts have been directed to extend postharvest conservation using cold storage and associated technologies such as plant regulators (Zhang et al, 2015), modified atmospheres , and polysaccharidebased coating (Lima et al, 2012). However, these approaches need to be optimized in terms of improving the barrier properties of the coatings (Dhall, 2013).…”

Pineapple is a tropical fruit of great consume demand. However, due to its high perishability at room conditions, there is noticeable loss of quality postharvest in a short period. In this context, the use of biodegradable coatings is a promising alternative for maintaining postharvest quality. Thus, the aim of this study was to evaluate the use of cassava starch-alginate based biodegradable coatings added with ascorbic acid and an elicitor on postharvest quality and conservation of 'Pérola' pineapple. Fruits were coated with: Cassava starch 1.5% + alginate 0.5%; cassava starch 1.5% + alginate 0.5% + ascorbic acid 0.18 %; cassava starch 1.5% + alginate 0.5% + elicitor, each added of 0.5% of glycerol as a plasticizer, and the control (uncoated fruits), following storage at room conditions (23 ± 1°C, 88 ± 2% RH). Pineapples coated with cassava starch-alginate associated with the elicitor (SE) or ascorbic acid (SA) kept lower levels of reducing and total sugars as well as better appearance and general acceptance (GA) during room storage for 18 days. According to the panelists, the determining factors for higher GA of 'Pérola' pineapple under these coatings were the sweetness, fresh like characteristics of taste and odor, and better appearance. Overall, the use of SE and SA coatings had a marked impact in maintained the quality during 18 days and did not adversely affect the sensory characteristics of 'Pérola' pineapple stored at room conditions.
