Special Issue Information

Dear Colleagues,

Climate change is negatively impacting not only food security, but also agricultural ecosystems. Frequent and intensified changes in extreme weather events make it hard to maintain sustainable agricultural production. One effective means of improving crop production and quality is through the development of stress-resistant cultivars.

In response to adverse environmental stressors, crops undergo adaptation, i.e., long-term evolutionary changes, and acclimation, i.e., short-term adjustment processes. Understanding the underlying dynamics and mechanisms of such alterations that enable crops to survive stressful environments and evaluating genetic variation in stress tolerance are prerequisites for breeding stress-resistant cultivars.

Targeted metabolite profiling provides a functional link between the pre-defined intermediate or final products of crop responses and environmental changes such as biotic and abiotic stresses. Furthermore, when metabolomics is integrated with other profiling technologies, such as transcriptomics and proteomics, it becomes an even more invaluable means of evaluating and screening germplasm collections for crop breeding programs.

This Special Issue focuses on the metabolic regulation and gene expression of crops under stress and the evaluation of the germplasm for crop breeding purposes.

Research articles can cover a broad range of crops, including not only agronomic crops but also horticultural crops such as vegetables, fruits, ornamentals, and lawn grasses.

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. Agriculture 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). 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.

When plants encounter external environmental stimuli, they can adapt to environmental changes through a complex network of metabolism–gene expression–metabolism within the plant cell. In this process, changes in the characteristics of plant cells are a phenotype that is responsive and directly linked to this network. Accurate identification of large numbers of plant cells and quantitative analysis of their cellular characteristics is a much-needed experiment for in-depth analysis of plant metabolism and gene expression. This study aimed to develop an automated, accurate, high-throughput quantitative analysis method, ACFVA, for single-plant-cell identification. ACFVA can quantitatively address a variety of biological questions for a large number of plant cells automatically, including standard assays (for example, cell localization, count, and size) and complex morphological assays (for example, different fluorescence in cells). Using ACFVA, phenomics studies can be carried out at the plant cellular level and then combined with ever-changing sequencing technologies to address plant molecular biology and synthetic biology from another direction.
