Special Issue Information

Dear Colleagues,

As an important grain and oilseed crop, the nitrogen fixation capacity and nodule formation mechanism of soybean have been attracting much attention. This Special Issue aims to present the latest research progress in the field of soybean nodule formation, nitrogen fixation and molecular regulation, soybean genetics, genomics, germplasm mining and related biology progress in bio-nitrogen fixation and to provide a platform for scientists to communicate and share innovative ideas.

We especially welcome submissions on the latest research on soybean nodule development, molecular regulatory mechanisms in nitrogen fixation, as well as cutting-edge technologies and methods in related fields. We look forward to receiving original and prospective studies covering a wide range of aspects from basic science to applied fields. Possible topics include, but are not limited to, the diversity of symbiotic rhizobial microorganisms in soybean, signaling networks during rhizome formation, structure and function of nitrogen-fixing enzymes, and the application of gene editing technology in soybean nitrogen fixation research.

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). 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 type III secretion system (T3SS) of Rhizobium plays a crucial role during the establishment of the soybean (Glycine max (L.) Merr.)-Rhizobium symbiosis system. Additionally, host-specific nodulation may also depend on the Nops (nodulation outer proteins) secreted by the T3SS of [...] Read more.
The type III secretion system (T3SS) of Rhizobium plays a crucial role during the establishment of the soybean (Glycine max (L.) Merr.)-Rhizobium symbiosis system. Additionally, host-specific nodulation may also depend on the Nops (nodulation outer proteins) secreted by the T3SS of Rhizobium. However, there is limited understanding of the response of soybean genes to Nops. In this study, a NopC mutant, HH103ΩNopC, was constructed from Sinorhizobium fredii HH103 and then utilized to assess the impact of the NopC on nodulation. An RNA-seq analysis revealed that the GmERF5 (Glycine max Ethylene Responsive Factor 5) gene was induced by NopC, which was confirmed by qRT-PCR. Furthermore, an overexpression of the GmERF5 hair-root system was constructed to investigate the effect of GmERF5 on nodulation and its interaction with NopC. Differences in nodule number and nodule dry weight in the overexpression of the GmERF5 hair-root system supported the conclusion that GmERF5 can regulate soybean nodule phenotype via NopC. These results elucidate the genetic mechanisms that regulate nodule phenotype in soybean. Full article
