A study of the effect of the thin layer of free water in corn kernels on the emissivity and interference in the mid infrared range was performed. The emissivity was measured through thermal infrared images by direct method for 8 days, allowing observance that the thickness of free water modifies the quantity of emitted energy and emissivity; however, in the first days when the layer of free water is not optically thick the interference caused by the thin film of superficial water averts a correct measurement of the emissivity...

Senescence is a key factor resulting in deterioration of non-climacteric fruit. NAC transcription factors are important regulators in plant development and abiotic stress responses, yet little information regarding the role of NACs in regulating non-climacteric fruit senescence is available. In this study, we cloned 13 NAC genes from litchi (Litchi chinensis) fruit, and analyzed subcellular localization and expression profiles of these genes during postharvest natural and low-temperature-delayed senescence...

Fusarium wilt incited by Fusarium oxysporum f. sp. niveum (FON) is a seed-transmitted disease that causes significant yield loss in watermelon production. The pathogen may infect watermelon seeds latently, which can be an important inoculum source and contribute to severe disease outbreak. However, information regarding infection courts of FON leading to infestation of watermelon seeds is limited. To determine how seeds in watermelon fruit can be infested by FON during the watermelon growing season, greenhouse and field experiments were conducted in 2014 and 2015 where watermelon flowers and immature fruit were inoculated with FON...

Asexual cool-season grass endophytes of the genus Epichloë (Ascomycota: Clavicipitaceae) are strictly vertically disseminated. The hosts of these mutualistic fungi express no symptoms during the fungal lifecycle that takes place entirely within the plant, while their hosts receive beneficial outcomes. These fungi are distributed in two major locations within the mature seeds of their hosts; namely, within the embryo (including the scutellum, coleoptile, plumule, radicle, and coleorhiza tissues) and between the aleurone and pericarp layers, with the latter hyphae playing no role in transmission of the fungus to the next plant generation...

Pectate lyase genes have been documented as excellent candidates for improvement of fruit firmness. However, implementation of pectate lyase in regulating fruit postharvest deterioration has not been fully explored. In this report, 22 individual pectate lyase genes in tomato were identified, and one pectate lyase gene SlPL (Solyc03g111690), showed dominant expression during fruit maturation. RNA-interference of SlPL resulted in enhanced fruit firmness and changes in pericarp cells. More importantly, the SlPL-RNAi fruit demonstrated greater anti-rotting and pathogen-resisting ability...

In angiosperms, the ovary wall resumes growth after pollination through a balanced combination of cell division and cell expansion. The quantitative pattern of these events remains poorly known in fleshy fruits such as tomato (Solanum spp.), in which dramatic growth of the pericarp occurs together with endoreduplication. Here, this pattern is reported at the level of each of the cell layers or groups of cell layers composing the pericarp, except for vascular bundles. Overall, cell division and cell expansion occurred at similar rates for 9 days post anthesis (DPA), with very specific patterns according to the layers...

The purpose of this study was to investigate the protective effects and mechanisms of the essential oil of Zanthoxylum bungeanum pericarp (ZBEO) on dextran sulfate sodium (DSS)-induced experimental colitis in mice. ZBEO decreased DSS-induced body weight loss, the disease activity index, colon length shortening, colonic pathological damage, and myeloperoxidase activities. The production of pro-inflammatory mediators was significantly alleviated by ZBEO. Further mechanistic analysis showed that ZBEO inhibited inflammation by regulating NF-κB and PPARγ pathways...

In higher plants, many mitochondrial genes contain group II-type introns that are removed from RNAs by splicing to produce mature transcripts that are then translated into functional proteins. However, the factors involved in the splicing of mitochondrial introns and their biological functions are not well understood in maize. Here, we isolated an empty pericarp 10 (emp10) mutant and identified the underlying gene by map-based cloning. Emp10 encodes a P-type mitochondria-targeted pentatricopeptide repeat (PPR) protein with 10 PPR motifs...

Weedy rice (Oryza spp.), a weedy relative of cultivated rice (O. sativa), infests and persists in cultivated rice fields worldwide. Many weedy rice populations have evolved similar adaptive traits, considered part of the "agricultural weed syndrome," making this an ideal model to study the genetic basis of parallel evolution. Understanding parallel evolution hinges on accurate knowledge of the genetic background and origins of existing weedy rice groups. Using population structure analyses of South Asian and US weedy rice, we show that weeds in South Asia have highly heterogeneous genetic backgrounds, with ancestry contributions both from cultivated varieties (aus and indica) and wild rice...

The bright and intense blue-green coloration of the fruits of Margaritaria nobilis (Phyllanthaceae) was investigated using polarization-resolved spectroscopy and transmission electron microscopy. Optical measurements of freshly collected fruits revealed a strong circularly polarized reflection of the fruit that originates from a cellulose helicoidal cell wall structure in the pericarp cells. Hyperspectral microscopy was used to capture the iridescent effect at the single-cell level.

As compared with P. longanae-inoculated longans, DNP treatment for P. longanae-inoculated longans exhibited higher fruit disease index and pericarp browning index, lower ATP amount and energy charge level, lower activities of SOD, CAT and APX, lower amounts of AsA and GSH, lower levels of DPPH radical scavenging activity and reducing power, higher O2(-) generating rate and MDA amount. However, supply of ATP for P. longanae-inoculated longans showed the contrary effects. These results gave convincing evidence that DNP treatment for accelerating pericarp browning and disease development of harvested longans caused by P...

Pigments of pericarp and pulp of pink guava (Psidium guajava L. cv. ´Criolla´) were investigated to elucidate the profile and the accumulation of main carotenoids during four stages of fruit ripening by using HPLC-DAD and APCI-MS/MS analysis. Seventeen carotenoids were identified and changes in their profile during fruit ripening were observed. The carotenoids all-trans-β-carotene, 15-cis-lycopene, and all-trans-lycopene were present in all ripening stages, but all-trans-lycopene was found to be predominant (from 63 % to 92 % of total carotenoids) and responsible for the high lipophilic antioxidant capacity determined by spectrophotometric assays...

The tautomeric pair of garcinielliptone FC (GFC) is a novel tautomeric pair of polyprenyl benzophenonoid isolated from the pericarps of Garcinia subelliptica Merr. (G. subelliptica, Clusiaceae), a tree with abundant sources of polyphenols. Our previous report demonstrated that GFC induced apoptosis on various types of human cancer cell lines including chemoresistant human colorectal cancer HT-29 cells. In the present study, we observed that many autophagy-related genes in GFC-treated HT-29 cells were up- and down-regulated using a cDNA microarray containing oncogenes and kinase genes...

Condensed tannins (also called proanthocyanidins) present in strategic tissues of fruits (outer pericarp and vascular bundles) were known as short polymers of flavan-3-ols. A pretreatment of the plant material (fruits from the grapevine, persimmon) with buffered ascorbic acid and Triton X-100 followed by acetone extraction provided native white fully depolymerizable tannins. Tannins are usually extracted with aqueous solvents and further purified, although artifactual oxidations occur, altering their physicochemical characteristics...

Mangosteen (Garcinia mangostana Linn.) is a well-known tropical tree indigenous to Southeast Asia. Its fruit's pericarp abounds with a class of isoprenylated xanthones which are referred as mangostins. Numerous in vitro and in vivo studies have shown that mangostins and their derivatives possess diverse pharmacological activities, such as antibacterial, antifungal, antimalarial, anticarcinogenic, antiatherogenic activities as well as neuroprotective properties in Alzheimer's disease (AD). This review article provides a comprehensive review of the pharmacological activities of mangostins and their derivatives to reveal their promising utilities in the treatment of certain important diseases, mainly focusing on the discussions of the underlying molecular targets/pathways, modes of action, and relevant structure-activity relationships (SARs)...
