Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue on ‘Advances in the Identification and Characterization of Plant Genes’ that will be published in the International Journal of Molecular Sciences. This Special Issue aims to provide a comprehensive overview of the latest research in the field of plant gene identification and characterization.

Plant genomes are incredibly complex, and identifying and characterizing individual genes within them is a significant challenge. However, advances in sequencing technologies and bioinformatics tools have made it possible to overcome many of these challenges and enhance our understanding of plant genomics.

This Special Issue will address a wide range of topics related to plant gene identification and characterization, including genome sequencing and annotation, transcriptomics, proteomics, and functional analysis. We welcome original research articles, reviews, and perspectives that address these topics and provide new insights into the molecular mechanisms that underlie plant growth, development, and responses to biotic and abiotic stress.

We encourage submissions from researchers across the globe who are currently employed in plant genomics and welcome contributions that reflect both fundamental and applied research. Our aim is to assemble cutting-edge research that will promote advancements in our understanding of plant gene regulation and pave the way for the development of new and improved crops.

We look forward to receiving your submissions and to sharing this exciting collection of research with our readers.

Dr. Frank M. You
Guest Editor

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Abstract

The SPL (SQUAMOSA-promoter binding protein-like) gene family is one of the largest plant transcription factors and is known to be involved in the regulation of plant growth, development, and stress responses. The genome-wide analysis of SPL gene members in a diverse range of crops has been elucidated. However, none of the genome-wide studies on the SPL gene family have been carried out for oil palm, an important oil-yielding plant. In this research, a total of 24 EgSPL genes were identified via a genome-wide approach. Phylogenetic analysis revealed that most of the EgSPLs are closely related to the Arabidopsis and rice SPL gene members. EgSPL genes were mapped onto the only nine chromosomes of the oil palm genome. Motif analysis revealed conservation of the SBP domain and the occurrence of 1–10 motifs in EgSPL gene members. Gene duplication analysis demonstrated the tandem duplication of SPL members in the oil palm genome. Heatmap analysis indicated the significant expression of SPL genes in shoot and flower organs of oil palm plants. Among the identified EgSPL genes, a total 14 EgSPLs were shown to be targets of miR156. Real-time PCR analysis of 14 SPL genes showed that most of the EgSPL genes were more highly expressed in female and male inflorescences of oil palm plants than in vegetative tissues. Altogether, the present study revealed the significant role of EgSPL genes in inflorescence development. Full article

Genome-Wide Identification of MADS-Box Genes in Taraxacum kok-saghyz and Taraxacum mongolicum: Evolutionary Mechanisms, Conserved Functions and New Functions Related to Natural Rubber Yield Formation

Abstract

MADS-box transcription regulators play important roles in plant growth and development. However, very few MADS-box genes have been isolated in the genus Taraxacum, which consists of more than 3000 species. To explore their functions in the promising natural rubber (NR)-producing plant Taraxacum kok-saghyz (TKS), MADS-box genes were identified in the genome of TKS and the related species Taraxacum mongolicum (TM; non-NR-producing) via genome-wide screening. In total, 66 TkMADSs and 59 TmMADSs were identified in the TKS and TM genomes, respectively. From diploid TKS to triploid TM, the total number of MADS-box genes did not increase, but expansion occurred in specific subfamilies. Between the two genomes, a total of 11 duplications, which promoted the expansion of MADS-box genes, were identified in the two species. TkMADS and TmMADS were highly conserved, and showed good collinearity. Furthermore, most TkMADS genes exhibiting tissue-specific expression patterns, especially genes associated with the ABCDE model, were preferentially expressed in the flowers, suggesting their conserved and dominant functions in flower development in TKS. Moreover, by comparing the transcriptomes of different TKS lines, we identified 25 TkMADSs related to biomass formation and 4 TkMADSs related to NR content, which represented new targets for improving the NR yield of TKS.
