The mutation of ent-kaurenoic acid oxidase, a key enzyme involved in gibberellin biosynthesis, confers a dwarf phenotype to cucumber.

A dwarf mutant with short branches (csdf) was identified from EMS-induced mutagenesis. Bulked segregant analysis sequencing and map-based cloning revealed CsKAO encoding ent-kaurenoic acid oxidase as the causal gene. Plant architecture is the primary target of artificial selection during domestication and improvement based on the determinate function for fruit yield.

Fine mapping of a major co-localized QTL associated with self-incompatibility identified in two F populations (broccoli × cauliflower and cauliflower × Chinese kale).

A major QTL responsible for self-incompatibility was stably identified in two F populations. Through fine mapping and qRT-PCR analysis, ARK3 emerged as the most promising candidate gene, playing a pivotal role in regulating self-incompatibility in Brassica oleracea. Self-incompatibility (SI) is a common phenomenon in Brassica oleracea species, which can maintain genetic diversity but will also limit seed production.

[Impact of Climate Change and Human Activities on the Ecological Sensitivity of the Yangtze River Economic Belt].

The increasing climate change and human activities exert their influence on the ecological sensitivity of the region individually and interactively. Therefore, a clear understanding of the impact of climate change and human activities on ecological sensitivity will enhance the resilience of the regional ecological environment and the level of sustainable development. This study took the Yangtze River Economic Belt, the first demonstration zone of China's ecological civilization construction, as the research object.

Unravelling Glucoraphanin and Glucoerucin Metabolism across Broccoli Sprout Development: Insights from Metabolite and Transcriptome Analysis.

Variations in the concentration of glucoraphanin (GRA) and glucoerucin (GER), as well as the corresponding breakdown products, isothiocyanates (ITCs) and nitriles, were investigated during the growth of broccoli sprouts. The concentrations of GRA and GER decreased sharply from 33.66 µmol/g to 11.

A mutation in CsABCB19 encoding an ATP-binding cassette auxin transporter leads to erect and compact leaf architecture in cucumber (Cucumis sativus L.).

Leaf architecture, including leaf position and leaf morphology, is a critical component of plant architecture that directly determines plant appearance, photosynthetic utilization, and ultimate productivity. The mechanisms regulating leaf petiole angle and leaf flatness in cucumber remain unclear. In this study, we identified an erect and compact leaf architecture mutant (ecla) from an EMS (ethyl methanesulfonate) -mutagenized cucumber population, which exhibited erect petioles and crinkled leaves.

Fine mapping of CscpFtsY, a gene conferring the yellow leaf phenotype in cucumber (Cucumis sativus L.).

Background: Leaf color mutants are ideal materials to study pigment metabolism and photosynthesis. Leaf color variations are mainly affected by chlorophylls (Chls) and carotenoid contents and chloroplast development in higher plants. However, the regulation of chlorophyll metabolism remains poorly understood in many plant species.

Evaluate cities' urban water resources system resilience along a river and identify its critical driving factors.

The emergence of a series of problems, such as serious water environment pollution and flood disasters, leads to an increase in an urban water resources system's vulnerability and pressure. In order to alleviate an urban water resources crisis, calculating the water resources system resilience (WRSR) and identifying its impact factors are essential. This paper constructed a resilience evaluation framework of the "Economy-Social Development-Infrastructure-Water Resources-Ecological Environment" water resources system from three stages, i.

A SNP mutation in the CsCLAVATA1 leads to pleiotropic variation in plant architecture and fruit morphogenesis in cucumber (Cucumis sativus L.).

Plant architectures is predominantly determined by branching pattern, internode elongation, phyllotaxis, shoot determinacy and reproductive organs. Domestication or improvement of this critical agronomic trait played an important role in the breakthrough of crop yield. Here, we identified a mutant with fasciated plant architecture, named fas, from an ethyl methanesulfonate (EMS) induced mutant population in cucumber.

The mutation of C-24 reductase, a key enzyme involved in brassinolide biosynthesis, confers a novel compact plant architecture phenotype to cucumber.

A novel compact plant architecture mutant, cpa-2, was identified from EMS-induced mutagenesis. Bulked segregant analysis sequencing and map-based cloning revealed CsDWF1 encoding C-24 reductase enzyme as the candidate gene. The compact architecture is a vital and valuable agronomic trait that helps to reduce the labor of plant management, and improve the fruit yield by increasing planting density in cucumbers.

Long-distance control of pumpkin rootstock over cucumber scion under drought stress as revealed by transcriptome sequencing and mobile mRNAs identifications.

Grafting with pumpkin rootstock is commonly used not only to improve the quality of cucumber fruits but also to confer biotic or abiotic stress tolerance. However, the molecular mechanism of grafted cucumbers to drought stress and the possible roles of mobile mRNAs to improve stress tolerance have remained obscure. Hence, we conducted transcriptome sequencing and combined it with morpho-physiological experiments to compare the response of homografts (cucumber as scion and rootstock) (C) and heterografts (cucumber as scion and pumpkin as rootstock) (P) to drought stress.

A SNP Mutation in Homeodomain-DDT (HD-DDT) Transcription Factor Results in () in Cucumber ( L.).

Trichome is a natural physical barrier protecting plants against environmental stresses, natural infestations, ultraviolet rays and pathogenicity. Trichome also helps plants in maintaining appropriate water content by reducing transpiration rate. The molecular mechanism regulating unicellular trichome development in Arabidopsis has been extensively elucidated, but the molecular mechanism regulating multicellular trichome development remains unclear.

Identification of a putative candidate gene encoding 7-dehydrocholesterol reductase involved in brassinosteroids biosynthesis for compact plant architecture in Cucumber (Cucumis sativus L.).

By the strategy of bulked segregant analysis sequencing combined with genetic mapping, CsDWF5, which encodes 7 dehydrocholesterol reductase that involved in brassinosteroids biosynthesis, was identified as the candidate gene for cpa. Dwarf architecture is one of the most important breeding goals in crops. The biosynthesis and signal transduction of brassinosteroids (BRs) have a great impact on plant growth and development including plant architecture.

An irregularly striped rind mutant reveals new insight into the function of PG1β in cucumber (Cucumis sativus L.).

Via bulked segregant analysis sequencing combined with linkage mapping, the ist gene responsible for the irregularly striped rind mutation was delimited to a 144-kb region in cucumber. Sequencing and expression analysis identified Csa1G005490 as the candidate gene. The rind appearance of cucumber is one of the most important commercial quality traits.

Fine Mapping of , Conferring Virescent Leaf Through the Regulation of Chloroplast Development in Cucumber.

Leaf color mutants in higher plants are ideal materials for investigating the structure and function of photosynthetic system. In this study, we identified a cucumber (virescent-yellow leaf) mutant in the mutant library, which exhibited reduced pigment contents and delayed chloroplast development process. F and BC populations were constructed from the cross between mutant and cucumber inbred line 'Hazerd' to identify that the trait is controlled by a simply recessive gene designated as The gene was mapped to a 3.
