Tissue slices of zucchini squash (Cucurbita pepo L., cv. Tigress) fruit were exposed to ultraviolet-C (UV-C) radiation from germicidal lamps for 1, 10 or 20 min; however, only 10 and 20 min UV-C exposure significantly reduced microbial activity and deterioration during subsequent storage at 5 or 10
Watersoaking is an ethylene-induced disorder observed in some members of the Cucurbitaceae including cucumber (Cucumis sativus L.), watermelon (Citrullus lanatus Thunb. Matsum and Nakai), and tropical pumpkin (Cucurbita moschata Duch.). Previous studies have found that immature beit-alpha cucumber
The quality of seeds in gene banks gradually deteriorates during long-term storage, which is probably, at least in part, a result of the progressive development of oxidative stress. Here, we report a greenhouse study that was carried out to test whether a novel approach of seed invigoration using
Lisianthus necrosis virus (LNV) was first identified as a fungus-borne virus that induced systemic necrosis in lisianthus (Eustoma russellianum) in Japan (2). In Taiwan, LNV causes systemic bright yellow chlorosis followed by necrosis in lisianthus (1). The disease was able to spread through the
Lisianthus (Eustoma exaltatum (L.) Salisb. ex G. Don subsp. russellianum (Hook.) Kartesz) is an economically important ornamental crop in Taiwan. Over the past decade, nine viruses have been identified or detected in lisianthus including: Bean yellow mosaic virus (BYMV), Lisianthus necrosis virus
In the summers and falls of 2008 and 2009, cucurbit plants (squash, Cucurbita pepo L.; cucumber, Cucumis sativus L.; and melon, Cucumis melo L.) from 23 of 33 cucurbit fields surveyed at three districts (Jenin, Nablus, and Tulkarm) in the West Bank of the Palestinian Authority exhibited curled,
During September 2006, moderate vine decline symptoms including vine collapse and wilt and root rot were observed on numerous watermelon plants growing in a commercial field in Sullivan County, Indiana. No symptoms were observed on the fruit. Six plants displaying typical vine decline symptoms were
Darkness mediates different senescence-related responses depending on the targeting of dark treatment (whole plants or individual leaves) and on the organs that perceive the signal (leaves or cotyledons). As no data are available on the potential role of darkness to promote senescence when applied
Pepocin, isolated from Cucurbita pepo, is a ribosome-inactivating protein (RIP). RIPs site-specifically recognize and depurinate an adenosine at position 4324 in rat 28 S rRNA, rendering the ribosome incapable of interacting with essential elongation factors. Aptamers that target pepocin were
This study investigates the efficacy of short peptides secreted by Bacillus subtilis for fungi inhibition and shelf-life maintenance of fresh-cut pumpkin.Low-molecular-weight filtrate (LC< 1,000 Da) of B. subtilis culture (BC) significantly lowered the Exposures to hazardous chemicals including formaldehyde are harmful to human health. In this study, the authors investigate the protective effects of pumpkin seed oil (PSO) extract against formaldehyde-induced major organ damages in mice. Administration of formaldehyde (FA) caused significant
Pumpkin (Cucurbita maxima) is an economically important vegetable crop of the family Cucurbitaceae. Yellow mosaic in C. maxima was observed in and around Lucknow, India, during the winter season of 1999-2000. High populations of whiteflies (Bemisia tabaci) were associated with diseased plants.
OBJECTIVE
Aside from those on Arabidopsis, very few studies have focused on spatial expression of cyclin-dependent kinases (CDKs) in root apical meristems (RAMs), and, indeed, none has been undertaken for open meristems. The extent of interfacing between cell cycle genes and plant growth regulators
The first committed step in the formation of diterpenoids leading to gibberellin (GA) biosynthesis is the conversion of geranylgeranyl diphosphate (GGDP) to ent-kaurene. ent-Kaurene synthase A (KSA) catalyzes the conversion of GGDP to copalyl diphosphate (CDP), which is subsequently converted to
In June 2002, mosaic and interveinal chlorosis were observed on two cucumber plants (Cucumis sativus) grown in one commercial greenhouse in the western region of Poland. Electron microscopic examination of leaf-dip preparations from infected plants showed flexuous filamentous virus particles typical
