The black-rot fungus, Myeosphaerella melonis (Pass.) Chiu and J. C. Walker, was first reported in France in 1891 on leaves of a Chinese variety of cucumber {CueUQyiis sativus L.) (¡^i) .^ It was recorded the next year from Delaware on vines of watermelon {Gitrullus vulgaris Sehr ad.), squash {Cucúrbita spp.), pumpkin {Cucúrbita pepo L.), muskmelon {Cucumis meló L.), and cucumber {3). Grossenbac...

AtDIR1 (Defective in Induced Resistance1) is an acidic lipid transfer protein essential for systemic acquired resistance (SAR) in Arabidopsis thaliana. Upon SAR induction, DIR1 moves from locally infected to distant uninfected leaves to activate defense priming; however, a molecular function for DIR1 has not been elucidated. Bioinformatic analysis and in silico homology modeling identified puta...

Fatty acid desaturases (FADs) introduce double bonds into the hydrocarbon chains of fatty acids to produce unsaturated fatty acids, and therefore play a critical role in plant development and acclimation to environmental stresses. In this study, 23 full-length FAD genes in cucumber (Cucumis sativus L.) were identified through database searches, including three CsFAB2 genes, two CsFAD2 genes, fo...

aphis gossypii glover is one of the most important pests of greenhouse cucumber and pepper in the world and iran. in this research, life table and biology of a. gossypii were investigated on cucumber (cucumis sativus cv. super sultan) and pepper (capsicum annum cv. marqueza) in a growth chamber at 25±1°c and 60±5% rh and a photoperiod of 14 l: 10 d hour.the results showed thatdevelopmental time...

MicroRNAs (miRNAs) are endogenous small RNAs playing an important regulatory function in plant development and stress responses. Among them, some are evolutionally conserved in plant and others are only expressed in certain species, tissue or developmental stages. Cucumber is among the most important greenhouse species in the world, but only a limited number of miRNAs from cucumber have been id...

Cucumber Fusarium wilt, induced by Fusarium oxysporum f. sp. cucumerinum (FOC), causes severe losses in cucumber yield and quality. Nitrogen (N), as the most important mineral nutrient for plants, plays a critical role in plant-pathogen interactions. Hydroponic assays were conducted to investigate the effects of different N forms (NH₄⁺ vs. NO₃‒) and supply levels (low, 1 mM; high, 5 mM) on cucu...

Additional Index Words. Cucumis sativus L., greenhouse, protected culture, beit alpha cucumber Abstract. The Beit Alpha (BA) cucumber is a new commodity for the Florida greenhouse industry. In past trials, BA cultivar production and quality were compared to traditional ‘Dutch’ or European cucumber cultivars. The cv. Sarig, a BA-type, produced three times more yield than the Dutch-type cv. Kalun...

A rapid, highly sensitive and selective method was developed for the determination of the cyantraniliprole and its major metabolite J9Z38 in cucumber, tomato and soil by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Target compounds were extracted with acetonitrile and an aliquot cleaned with primary and secondary amine. Two pairs of precursor product ion transi...

Among the fundamental questions regarding cultivated plants is their geographic origin and region of domestication. The genus Cucumis, which includes cucumber (Cucumis sativus) and melon (Cucumis melo), has numerous wild African species, and it has therefore been assumed that melon originated in Africa. For cucumber, this seemed less likely because wild cucumbers exist in India and a closely re...

To provide an insight into the mechanism of interspecific interactions mediated by allelochemicals, cucumber and figleaf gourd seedlings were compared on their response to cinnamic acid, an autotoxin from root exudates of cucumber. Reactive oxygen species metabolism and plasma membrane H(+)-ATPase activity were examined in roots upon exposure to cinnamic acid. This exposure resulted in signific...
