Special Issue Information

Dear Colleagues,

Background & history of this topic: The need for the sustainable production food and responding to a changing climate are driving advances in modern crop breeding programs. Crop domestication has always relied on traditional phenotypic selection to obtain dominant traits, but genomic interventions could accelerate advances in crop improvement. However, linking phenotypes to genotypes remains a significant challenge in the improvement of modern crops. Proteins execute direct biological functions, which require precise localization, the formation of complex high-level structures, post-translational modifications, and interaction with other proteins, which cannot be revealed by gene- and transcription-based studies. Therefore, proteomics plays an important role in deciphering functional mechanisms and enables us to enhance crops.

Aim and scope of the Special Issue: This Special Issue intends to provide novel insights into the application of proteomics technologies in crop improvement toward sustainable agriculture, including multi-omics integration analysis and related research on post-translational proteome modification (like acetylation, phosphorylation, ubiquitination and glycosylation modification), and also the exploration of new technologies for proteomics research.

Cutting-edge research: This Special Issue is devoted to genome design breeding research based on proteomics-related approaches. The Special Issue encourages the submission of groundbreaking work by researchers across disciplines.

What kind of papers we are soliciting:  Research articles, review articles as well as short communications are welcome.

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). 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.

Effect of Calcium Addition on Extracellular Enzymes and Soil Organic Carbon in Maize Rhizosphere Soils

This study examined the regulatory mechanism of calcium (Ca) amendment on the dynamics of soil organic carbon (SOC) fractions and extracellular enzyme activities, elucidating the role of Ca in soil carbon cycling processes. A field experiment with maize was conducted, comparing treatments of low calcium (T1), high calcium (T2), and a calcium-free control (CK). Measurements included inter-root SOC fractions—soluble organic carbon (DOC), microbial biomass carbon (MBC), and readily oxidizable organic carbon (ROC)—and the activities of the following extracellular enzymes: β-xylanase, β-glucosidase (β-glu), phenol oxidase (Phox), peroxidase (Pero), phosphatase (Phos), acetylaminoglucosidase (NAG), and urease. The main findings indicated the following: (1) Calcium addition significantly increased SOC content (115.04% and 99.22% higher in T1 and T2, respectively, than CK during the entire reproductive period) and enhanced microbial activity (elevated DOC and MBC). However, SOC decreased by 8.44% (T1) and 16.38% (T2) relative to CK in the late reproductive stage (irrigation–ripening), potentially reflecting microbial utilization (supported by the inverse correlation between SOC and MBC/DOC), and maize carbon reallocation during grain filling. (2) Calcium activated β-glu, Phox, Phos, NAG, and urease (p < 0.05), with pronounced increases in Phox (241.13 IU·L−1) and Phos (1126.65 U·L−1), indicating enhanced organic matter mineralization and phosphorus availability. (3) Calcium-driven MBC and ROC accumulation was associated with the positive regulation of Phox (path coefficient > 0.8) and the negative regulation of Phos. SOC was co-regulated by β-glu and Phos (R2 = 0.753). (4) Calcium dynamically optimized the short-term carbon distribution through enzyme activity while promoting long-term sequestration. Our study provides new evidence supporting multi-pathway interactions through which calcium mediates enzyme networks to influence the soil carbon cycle. The findings provide a theoretical foundation for calcium fertilizer management and soil carbon sequestration strategies in agriculture, advancing academic and practical goals for sustainable development and carbon neutrality.
