Special Issue Information

Dear Colleagues,

As part of evolution, domestication has enabled wild plants and animals to be cultivated and consumed. This domestication occurred spontaneously or by humans, to adapt to a new environment. As a result, plants have developed new traits, such as bigger branches, bigger and sweeter fruits, etc., in which many transcription factors have a major role. When, where, and how most horticultural crops are domesticated today is being elucidated by the combination of different disciplines: archaeobotany, breeding, biochemistry, bioinformatics, physiology, molecular biology, etc.

We welcome submissions on topics including (but not limited to): (1) domestication of plants; (2) transcription factors involved in important traits, such as dormancy, flowering time, fruit development; and (3) decision support tools and modeling.

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. Agronomy 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).

Genome-Wide Identification and Expression Analysis of MIKC-Type MADS-Box Gene Family in Punica granatum L.

by Yujie Zhao, Honglian Zhao, Yuying Wang, Xinhui Zhang, Xueqing Zhao and Zhaohe Yuan

Abstract

MADS-box is a critical transcription factor regulating the development of floral organs and plays essential roles in the growth and development of floral transformation, flower meristem determination, the development of male and female gametophytes, and fruit development. In this study, 36 MIKC-type MADS-box genes were identified in the ‘Taishanhong’ pomegranate genome. By utilizing phylogenetic analysis, 36 genes were divided into 14 subfamilies. Bioinformatics methods were used to analyze the gene structure, conserved motifs, cis-acting elements, and the protein interaction networks of the MIKC-type MADS-box family members in pomegranate, and their expressions pattern in different tissues of pomegranate were analyzed. Tissue-specific expression analysis revealed that the E-class genes (PgMADS03, PgMADS21, and PgMADS27) were highly expressed in floral tissues, while PgMADS29 was not expressed in all tissues, indicating that the functions of the E-class genes were differentiated. PgMADS15 of the C/D-class was the key gene in the development network of pomegranate flower organs, suggesting that PgMADS15 might play an essential role in the peel and inner seed coat development of pomegranate. The results in this study will provide a reference for the classification, cloning, and functional research of pomegranate MADS-box genes. Full article

Genome-wide Identification and Expression Analysis of TALE Gene Family in Pomegranate (Punica granatum L.)

by Yuying Wang, Yujie Zhao, Ming Yan, Honglian Zhao, Xinhui Zhang and Zhaohe Yuan

Abstract

The three-amino-acid-loop-extension (TALE) gene family is a pivotal transcription factor that regulates the development of flower organs, flower meristem formation, organ morphogenesis and fruit development. A total of 17 genes of pomegranate TALE family were identified and analyzed in pomegranate via bioinformatics methods, which provided a theoretical basis for the functional research and utilization of pomegranate TALE family genes. The results showed that the PgTALE family genes were divided into eight subfamilies (KNOX-Ⅰ, KNOX-Ⅱ, KNOX-Ⅲ, BELL-Ⅰ, BELL-Ⅱ, BELL-Ⅲ, BELL-Ⅳ, and BELL-Ⅴ). All PgTALEs had a KNOX domain or a BELL domain, and their structures were conservative. The 1500 bp promoter sequence had multiple cis-elements in response to hormones (auxin, gibberellin) and abiotic stress, indicating that most of PgTALE were involved in the growth and development of pomegranates and stress. Function prediction and protein-protein network analysis showed that PgTALE may participate in regulating the development of apical meristems, flowers, carpels, and ovules. Analysis of gene expression patterns showed that the pomegranate TALE gene family had a particular tissue expression specificity. In conclusion, the knowledge of the TALE gene gained in pomegranate may be applied to other fruit as well. Full article
