Special Issue Information

Dear Colleagues,

As is well known, relative to model plants, ornamental plants have many special characteristics. However, current regulatory models are mainly based on model plants. With the development of sequencing technology and omics tools, we can apply high-throughput sequencing and other omics methods to discover core regulatory networks and genes related to specific ornamental traits. These advances can provide assistance and excellent candidate genes for directional breeding. On the other hand, classical molecular biology methods have also been used to discover the regulatory mechanism of ornamental traits. This will also enrich our understanding of the development mechanism of plant-specific organs. Based on these, we have decided to launch this Special Issue on “Molecular Biology of Ornamental Plants”.

This Special Issue welcomes contributions from researchers working in the field of molecular biology of ornamental plants. Original research articles are encouraged for submission, focusing on but not limited to the following areas:

Biotechnology and genome editing;
Biotic or abiotic stress-resistant gene function in ornamental plants;
Integrative analysis of multi-omics;
Molecular regulatory mechanism of ornamental traits.

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).

Abstract

The Lanzhou lily (Lilium davidii var. unicolor) is a variant of the Sichuan lily of the lily family and is a unique Chinese ‘medicinal and food’ sweet lily. Somatic cell embryogenesis of Lilium has played an important role in providing technical support for germplasm conservation, bulb propagation and improvement of genetic traits. Somatic embryogenesis receptor-like kinases (SERKs) are widely distributed in plants and have been shown to play multiple roles in plant life, including growth and development, somatic embryogenesis and hormone induction. Integrating the results of KEGG enrichment, GO annotation and gene expression analysis, a lily LdSERK1 gene was cloned. The full-length open reading frame of LdSERK1 was 1875 bp, encoding 624 amino acids. The results of the phylogenetic tree analysis showed that LdSERK1 was highly similar to rice, maize and other plant SERKs. The results of the subcellular localisation in the onion epidermis suggested that the LdSERK1 protein was localised at the cell membrane. Secondly, we established the virus-induced gene-silencing (VIGS) system in lily scales, and the results of LdSERK1 silencing by Tobacco rattle virus (TRV) showed that, with the down-regulation of LdSERK1 expression, the occurrence of somatic embryogenesis and callus tissue induction in scales was significantly reduced. Finally, molecular assays from overexpression of the LdSERK1 gene in Arabidopsis showed that LdSERK1 expression was significantly enhanced in the three transgenic lines compared to the wild type, and that the probability of inducing callus tissue in seed was significantly higher than that of the wild type at a concentration of 2 mg/L 2,4-D, which was manifested by an increase in the granularity of the callus tissue.
