Crop Improvement Now and Beyond

Dear Colleagues, 

Since the green revolution in the early 1970s, crop production has mostly covered the human needs, allowing feeding a regularly growing population. However, yields have been stagnating for most crops—especially for cereals—for more than 20 years, and the surpluses that used to cover at least three months of consumption have dramatically decreased, leading to stock depletion with potentially disastrous consequences for human feeding. In addition, crops initially intended for human consumption have been diverted to non-food productions, thus further impacting food stocks. The traditional answer to the growing demands of the world population has also long relied on extending land cultivation, implementing large deforestation programs in some developing countries. Nevertheless, this will no longer be possible because of the non-negotiable need to preserve natural biodiversity. Agriculture has also to face increasing ecological constraints, and crop yield improvement will have to be achieved despite a drastic reduction of the use of fertilizers, herbicides, insecticides, and fungicides, and the scarcity of water caused by climate change and the frequent occurrence of drought and heat stress. Therefore, it is necessary to “give crops a genetic helping hand” and to provide breeders with new tools to allow the fast development of new original and powerful crop varieties. These achievements will require the application of cell and molecular biology techniques, high-throughput genotyping and sequencing approaches, genome-wide association mapping and genomic selection, gene expression and regulation methods, targeted mutagenesis, including genome editing, high-throughput phenotyping, epigenetics. The objective if this Topical Collection is to show how these new tools are being specifically setup and used for the improvement of major crops and how they will be used and improved in the coming years to face the challenge of crop yield improvement and meet human needs by 2050 in the context of sustainable agriculture. Review articles on the latest technologies and methodologies will also be of interest.

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. 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 collection 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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biology 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.
