Special Issue Information

Dear Colleagues,

Crop yield improvement remains a critical goal in sustainable agriculture, particularly in the face of the increasing global food demand, climate change, and limited natural resources. Advances in genetic and biological breeding have revolutionized our ability to enhance crop productivity by uncovering molecular mechanisms behind yield-related traits, developing precise genome-editing tools, and incorporating systems biology approaches. These innovations have not only improved crop performance under diverse environmental conditions but have also offered new insights into the genetic architecture of yield potential and stress resilience.

This Special Issue of Plants will focus on cutting-edge research on genetic and biological breeding for crop yield improvement. Possible topics include the discovery of yield-associated genes, advancements in molecular breeding, applications of CRISPR-based technologies, and the integration of phenomics and bioinformatics into breeding programs. We also welcome studies addressing abiotic stress tolerance mechanisms, epigenetic regulation, and the translation of foundational research to practical breeding strategies in major crops.

We invite contributions that advance our understanding of the genetic and biological bases of crop yield and suggest innovations to meet future agricultural challenges.

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. Plants 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 2700 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.

Calcium ions (Ca2+) are an important secondary messenger in plant signal transduction networks. The cytosolic free Ca2+ concentration ([Ca2+]i) of plants changes rapidly when they are subjected to different abiotic stresses, which drives calcium signaling. Although this process has been extensively studied in spermatophytes, the details of calcium signaling in bryophytes remains largely unknown. In our study, we reconstituted aequorin in the bryophyte Physcomitrella patens, optimized the percentage of ethanol in the Ca2+ discharging solution, and measured the [Ca2+]i changes induced by different stresses. In addition, we observed that the sources of Ca2+ accessed following exposure to cold, drought, salt, and oxidative stress were different. Furthermore, we showed that long-term saline environments could suppress the basal [Ca2+]i of P. patens, and the peak value of [Ca2+]i induced by different stresses was lower than that of plants growing in non-stressed environments. This is the first systematic study of calcium signaling in bryophytes, and we provided an efficient and convenient tool to study calcium signaling in response to different abiotic stresses in bryophytes.
