Special Issue Information
Dear Colleagues,
Gibberellin (GA) is one of the plant hormones regulating a wide range of processes involved in plant growth, organ development, and their responses to the environment. These include seed germination, stem elongation, leaf expansion, transition to flowering, and the development of flowers, fruits, and seeds. About 85 years ago, GA was first identified in the pathogenic fungus, Gibberella fujikuroi, as the causal chemical for the rice “bakanae” (foolish seedling) disease. Plants infected by such fungus show excessive leaf and culm (stem) elongation. Since this finding, more than 130 GAs have been subsequently identified in plants, fungi, and bacteria, and GA research has continued intensively.
The biosynthetic process of GA has always been one of major research topics in GA science, as it is directly related to crop yield, such as in the case of the rice ‘Green Revolution’ during the second half of the 20th century, which was accomplished through the application and popularization of semi-dwarf varieties owing to GA biosynthesis gene mutation, sd-1. Recent emerging studies have also provided important knowledge on the complex relationships between GA and other phytohormones and exogenous biotic/abiotic factors. These findings shed light on the importance of GA in controlling plant development again. In addition, recent genome information of nonmodel organisms has enabled us to investigate the evolutionary processes of GA biosynthesis in plants and microorganisms. In this Special Issue, studies from various research fields of GA biosynthesis, such as genetics, biochemistry, molecular biology, omics studies, agriculture, evolutionary studies, and so on, are all welcomed.

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 250 words) can be sent to the Editorial Office for assessment.
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. Genes is an international peer-reviewed open access monthly 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 2600 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.
