Special Issue Information

Dear Colleagues,

Members of the Cucurbitaceae family (e.g., watermelons, melons, cucumbers, squashes, pumpkins, and gourds), exhibit extensive diversity in plant habit and fruit type.  They are noteworthy for several unique biological characteristics, serving as model systems for features such as: vascular biology, source-sink interactions and inter-organ communication; interspecific graft compatibility; plant architecture, and climbing activity; plasticity of floral development, and hormonal signaling regulating sex expression patterns; diversity in fruit size, shape, color, and patterns, ripening biology, flavor, and aroma.  This special issue on ‘Developmental Biology of Cucurbitaceae’ welcomes papers that explore vegetative and reproductive developmental biology of cucurbit species using a variety of ecological, evolutionary, physiological, genetic, genomic, and molecular genetic approaches.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Cucumis debilis W.J.de Wilde & Duyfjes is an annual and monoecious plant. This species is endemic to Southeast Asia, particularly Vietnam. However, C. debilis is rarely studied, and no detailed information is available regarding its basic chromosome number, 45S ribosomal DNA (rDNA) status, and divergence among other Cucumis species. In this study, we characterized the morphological characters and determined and investigated the basic chromosome number and chromosomal distribution of 45S rDNA of C. debilis using the fluorescent in situ hybridization (FISH) technique. A maximum likelihood tree was constructed by combining the chloroplast and internal transcribed spacer of 45S rDNAs to infer its relationship within Cucumis. C. debilis had an oval fruit shape, green fruit peel, and protrusion-like white spots during the immature fruit stage. FISH analysis using 45S rDNA probe showed three pairs of 45S rDNA loci located at the terminal region in C. debilis, similar to C. hystrix. Meanwhile, two, two, and five pairs of 45S rDNA loci were observed for C. melo, C. metuliferus, and C. sativus, respectively. One melon (P90) and cucumber accessions exhibited different chromosomal localizations compared with other members of Cucumis. The majority of Cucumis species showed the terminal location of 45S rDNA, but melon P90 and cucumber exhibited terminal–interstitial and all interstitial orientations of 45S rDNA loci. Based on molecular cytogenetics and phylogenetic evidence, C. debilis is more closely related to cucumber than melon. Therefore, C. debilis may serve as a potential parental accession for genetic improvement of cucumber through interspecific hybridization. Full article

Cucumber (Cucumis sativus L.) is an annual climbing herb that belongs to the Cucurbitaceae family and is one of the most important economic crops in the world. The breeding of cucumber varieties with excellent agronomic characteristics has gained more attention in recent years. The size and shape of the leaves or fruit and the plant architecture are important agronomic traits that influence crop management and productivity, thus determining the crop yields and consumer preferences. The growth of the plant is precisely regulated by both environmental stimuli and internal signals. Although significant progress has been made in understanding the plant morphological regulation of Arabidopsis, rice, and maize, our understanding of the control mechanisms of the growth and development of cucumber is still limited. This paper reviews the regulation of phytohormones in plant growth and expounds the latest progress in research regarding the genetic regulation pathways in leaf development, fruit size and shape, branching, and plant type in cucumber, so as to provide a theoretical basis for improving cucumber productivity and cultivation efficiency.
