Special Issue Information

Dear Colleagues,

A wide variety of colorful plants make the earth more beautiful for us to live on, and are also an important basis for human survival. Differences in plant morphology are primarily due to genomic differences. Associations between morphological traits and genomes are particularly important for gene mining. With the continuous development of next generation sequencing technology, such as genome assembly and resequencing, plays an important role in interpreting morphological traits and gene mining. This Special Issue encourages authors to submit well-designed original research papers in all aspects of “Genomic Insights into Plant Morphological Traits”, such as genome assembly, pan-genome, molecular marker development, high-density genetic maps, QTL mapping, genome-wide association study, DNA methylation, and gene function analysis. Research on crops and horticultural crops across all types of morphological traits with genomic data is welcome.

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.

Potato (Solanum tuberosum L.) is an important food crop, but low temperature affects the potato growth and yield. In this study, the expression level of StBBX14 was significantly increased over 1 h and then gradually decreased under cold stress. The subcellular localization of the StBBX14 protein took place in the nucleus. The OE-StBBX14 transgenic lines showed less leaf damage and significantly lower electrolyte leakage compared with the WT under cold stress, indicating that the overexpression of StBBX14 in the potato enhanced the cold resistance. A transcriptome analysis showed that a total of 2449 and 6274 differentially expressed genes were identified in WT-1 h and WT-12 h, respectively, when compared with WT-0h. A Gene Ontology enrichment analysis revealed that photosynthesis, cell wall, thylakoid, transcription regulator activity, oxidoreductase activity and glucosyltransferase activity were significantly enriched in OE-StBBX14 and WT. A total of 14 distinct modules were generated by a WGCNA analysis based on all differentially expressed genes (DEGs). Four major modules with cold-related genes were isolated. RT-qPCR analysis showed that the expression patterns of eight DEGs were consistent between the qPCR and RNA-seq. These findings illustrate that the StBBX14 played an important role in cold stress in potato and provided a data basis for the genetic improvement of cold resistance traits of potato. Full article
