Abstract:
... The heterosis prediction has an essential role in hybrid breeding. The prediction of heterosis is highly dependable upon the selection of an efficient method, however, fewer methods have been used till date which lack or unable to explain several important aspects in heterosis prediction. Thus, in our experiment, we tried to explore a new heterosis prediction system based on genomic prediction, in ...

Abstract:
... This study was conducted to develop inbred backcross lines (IBLs) in Indian slicing cucumber (Cucumis sativus L.) with the gynoecious trait. The F₂ mapping population was developed using the Indian monoecious cultivar of light-green-fruited Pusa Uday as the recurrent parent and the American gynoecious pickling line G421 as a donor. Two markers, SSR13251 and SSR15516, were found to be closely linke ...

Abstract:
... Plants allocate their limited resources toward different physiological processes, dynamically adjusting their resource allocation in response to environmental changes. How beneficial plant-associated microbes influence this allocation is a topic that continues to interest plant biologists. In this study, we examined the effect of a beneficial fungus, Phialemonium inflatum, on investment in growth ...

Abstract:
... mRNAs are transported within a plant through phloem. Aphids are phloem feeders and dodders (Cuscuta spp.) are parasites which establish phloem connections with host plants. When aphids feed on dodders, whether there is trafficking of mRNAs among aphids, dodders, and host plants and if aphid feeding affects the mRNA transfer between dodders and hosts are unclear. We constructed a green peach aphid ...

Abstract:
... Cadmium (Cd) stress can cause system disorders in plants, affect the absorption of some nutrients. The roles and their relationship of salicylic acid (SA) and hydrogen peroxide (H₂O₂) in adventitious root formation (ARF) of cucumber (Cucumis sativus L.) under Cd stress were studied. The results showed that the exogenous SA and H₂O₂ in enhancing ARF in cucumber explants under Cd stress was concentr ...

Abstract:
... Corolla opening is essential for the propagation of unisexual flowering plants, meanwhile commodity fruits with opening corolla have higher commodity value in cucumber fresh food market. Until now, there is little research on the mechanism of corolla opening in cucumber. In a previous paper, we identified a unique cucumber (Cucumis sativus) line (‘6457’) that possesses super ovaries and shows dela ...

Abstract:
... The shape of fruit apex is critical to appearance quality in cucumber (Cucumis sativus L.), of which the genetic basis was poorly understood, and the use of marker-assisted breeding for fruit apex improvement is not available yet. In this study, the variation of fruit apex in different cucumber ecotypes was evaluated by fruit apex angle (variation coefficient from 7.1% to 15.7%) and fruit apex ind ...

Abstract:
... OVATE family proteins (OFPs) are plant-specific proteins with a conserved OVATE domain that regulate plant growth and development. Although OFPs have been studied in several species, their biological functions remain largely unknown in cucumber (Cucumis sativus L.). This study identified 19 CsOFPs distributed on seven chromosomes in cucumber. Most CsOFP genes were expressed in reproductive organs, ...

Abstract:
... P450 (cytochrome P450) is a supergene family, which is involved in various metabolic pathways in plants. Based on previous study, we found some of cucumber P450 mRNAs were systemic mobile in cucumber/pumpkin grafts. However, the reason that why P450 mRNAs were endorsed as signaling, and what specific motif (s) did they harbored is not clear yet. Here, we first identified 221 CsaP450 genes in cucum ...

Abstract:
... In situ mRNA hybridization (ISH) is a powerful tool for examining the spatiotemporal expression of genes in shoot apical meristems and flower buds of cucumber. The most common ISH protocol uses paraffin wax; however, embedding tissue in paraffin wax can take a long time and might result in RNA degradation and decreased signals. Here, we developed an optimized protocol to simplify the process and i ...

Abstract:
... BACKGROUND: Cold stress is one of the main abiotic stresses limiting cucumber (Cucumis sativus L.) growth and production. C-repeat binding factor/Dehydration responsive element-binding 1 protein (CBF/DREB1), containing conserved APETALA2 (AP2) DNA binding domains and two characteristic sequences, are key signaling genes that can be rapidly induced and play vital roles in plant response to low temp ...
... Cucumber (Cucumis sativus L.) is a popular warm season vegetable used for salads and grown throughout the world under tropical and subtropical conditions. The use of synthetic fertilizers for cucumber production over an extended time period can improve the productivity but consecutively deteriorates soil health. Therefore, with the hypothesis that for an extensive evaluation of different nutrient ...

Abstract:
... Cucurbitacin C-type cucurbitacins that are only identified in Cucumis sativus (cucumber) are, in part, responsible for the health benefits and bitter flavor. Nevertheless, detailed information about those functional ingredients in cucumber is scarce. In this study, ten cucurbitacin C analogues including seven undescribed ones have been isolated from the bitter leaves of cucumber, in which six comp ...

Abstract:
... The Xishuangbanna (XIS) cucumber is an important botanical variety, accumulating high levels of β-carotene (700 μg/100 g) in the endocarp of mature fruit compared with normal green/white flesh types (25–50 μg/100 g, fresh weight). β-carotene is an essential precursor of provitamin A synthesis required for human health, thus XIS cucumber is an appealing germplasm for vitamin A breeding programs. In ...
... Cucumber mosaic virus (CMV), which is one of the most prevalent plant viruses, harms many crops around the word. Although CMV causes severe economic losses to agriculture, successful prevention and treatment strategies are lacking. RNA interference (RNAi) is a promising strategy for the control of CMV because of its impressive specificity and sustainability. Here, a bacterial expression approach w ...

Wild cucumber (var. hardwickii) has been localized for the first time from Billawar, Kathua (District) in Union Territory of Jammu and Kashmir, India. Both are monoecious in sex expression and show unique arrangement of the appearance/de ...
... Several members of the genus Ilarvirus infect fruit trees and are distributed worldwide. Prunus necrotic ringspot virus (PNRSV) is one of the most prevalent viruses, causing significant losses. Cucumissativus can be infected by several ilarviruses, leading to obvious symptoms, including PNRSV, which suggests that cucumbers could be good hosts for the study of the pathogenesis of ilarviruses.

Abstract:
... The extraction of humic substances from weathered coal and peat has been regarded as an effective way to utilize these wastes. However, the effects of humic acid (HA) and sodium humate (HN) (derived from weathered coal and peat, respectively) on soil microbial dysbiosis remain elusive. By virtue of Illumina sequencing and FUNGuild, we investigated the interrelationships between soil microbial comm ...

Abstract:
... Crop plants encounter various biotic and abiotic stresses that hinder life throughout their growth and development. These factors certainly affect the productivity and quality of the final produce. In the post-genomics era, the accumulation of genomic resources has widened the crop breeding for complex traits. Cucumber (Cucumis sativus L.) is an important vegetable crop and has been a model plant ...
... Georgia vegetable growers produce more than 27% of the nation's fresh-market cucumbers. To maximize yields and profit, fields must be weed-free when planting. Limitations with current burndown herbicide options motivated academic, industry, and U.S. Department of Agriculture partners to search for new tools to assist growers. One possibility, glufosinate, controls many common and troublesome weeds ...
