Special Issue Information

Dear Colleagues,

Modern agriculture must address the increasing global demand for food. Among all of the possible targets to improve crop yield, photosynthesis stands out as a plant trait that remains significantly below its theoretical efficiency limit. Current solar energy to biomass conversion rates in field conditions are estimated to be lower than 1% (with an effective yield depending on the species). Enhancing crop photosynthesis presents a compelling challenge for modern scientists, requiring interdisciplinary collaboration across agronomy, biology, biotechnology, genetics, biophysics, and computational biology. Additionally, socioeconomic factors such as public resistance to genetically modified crops and unequal access to advanced technologies must be addressed, as they hinder the global implementation of these innovations.

This Special Issue seeks contributions that explore various aspects of the photosynthetic process aimed at improving photosynthetic efficiency in crops or enhancing plant productivity more broadly. Submissions are welcome in the form of original research articles, reviews, modelling studies, and methodological papers. These works may focus on topics ranging from molecular-level mechanisms to field-scale applications, encompassing areas such as biochemistry, physiology, genetics, evolutionary studies, and field trials involving both model and crop plants.

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. Agronomy 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 2600 CHF (Swiss Francs).

During crop growth, leaf photosynthetic capacity changes continuously, and the vertical distribution of leaf nitrogen (Na, in g m−2) and chlorophyll (Chla, in μg cm−2) affects photosynthesis in different canopy layers. Understanding stratified photosynthesis is vital for the accurate prediction of crop photosynthetic capacity. We conducted a two-year field study on winter wheat and paddy rice in Eastern China, measuring the leaf maximum carboxylation rate (Vcmax25), maximum electron transport rate (Jmax25), Na, and Chla every 7–10 days from greening to maturity. We analyzed vertical variations in these parameters in the upper (T-1), middle (T-2), and lower (T-3) canopy layers and explored relationships between Na/Chla and Vcmax25. The results showed significant vertical variations: Vcmax25 and Jmax25 in T-1 were higher than in T-2, and T-2 was higher than T-3. The vertical distribution of Na and Vcmax25 was more pronounced than that of Chla. The correlation between Na and Vcmax25 increased from T-1 to the lower layers, while the Vcmax25-Chla correlation decreased. A single Vcmax25 estimation model based on Na performed well across layers (R2 = 0.619, RMSE = 15.751 µmol m−2 s−1). Differentiating T-1 from T-2/T-3 improved the Chla-based models. Na was better than Chla for characterizing the Vcmax25 vertical variation, with the Chla-based models requiring separation of T-1 from T-2/T-3. This study provides key insights for remote sensing of photosynthetic parameters and improves the understanding of crop canopy photosynthesis. Full article
