Special Issue Information

Dear Colleagues,

This Special Issue, entitled 'Novel Insights into Buckwheat Reproductive Biology', aims to provide an excellent overview of the results of research carried out in recent years on the biology of flowering and the causes of low yield in Fagopyrum esculentum and F. tataricum. The cultivation of buckwheat, which belongs to the pseudo cereals, especially in Europe, has so far been marginal compared to other cereal crops. Due to the excellent chemical composition of its seeds, it is becoming increasingly important and is being promoted as a valuable element of the human diet. Unfortunately, unstable seed yield caused by sensitivity to unfavorable environmental factors makes its cultivation unprofitable. Low seed yield is caused by buckwheat's high sensitivity to many environmental stresses and, in the case of common buckwheat, by its specific floral biology. It is therefore worth analyzing how these two valuable buckwheat species can be improved through creative breeding, particularly using biotechnological methods.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Common buckwheat (Fagopyrum esculentum Moench), a valuable plant, is characterized by a highly unstable seed yield. The objective of the present study was to ascertain whether seed treatment with gamma radiation of 30 or 40 Gy would enhance yield and the content of amino acids. Plants obtained from irradiated seeds were named M0 generation. Subsequently, the mutants were subjected to cross-pollination under isolation conditions within groups, contingent upon the radiation dose, to yield the M1, M2, and M3 generations. To estimate the extent of mutation changes, genotyping by sequencing analysis was performed on selected M0 plants. Each year, the selection of plants was based on their seed yield. The amino acid composition in the seeds of the M2 and M3 generations was determined. The number of unique heterozygote variants identified for the 40 Gy plants was found to be less than that observed in remaining plants. The M0 and M1 plants of 40 Gy group exhibited an augmented seed yield; however, this characteristic did not reoccur in the M2 generation. In the M2, the control seeds exhibited the highest amino acid content compared to the mutants. In the M3 generation, only one accession of the 40 Gy group demonstrated higher amino acid content than the other plants. The findings suggest that irradiating seeds with 40 Gy can enhance seed yield and amino acid content. Full article
