Special Issue Information

Dear Colleagues,

Common oat (Avena sativa L.) is the most important species among the cultivated oats. It is widely used in both the feed and food industry because of its high nutritional value; oat products are a valuable source of dietary fiber, especially β-glucan, as well as protein, fat, minerals, and vitamins. Oat is known for its influence on satiety, retarded absorption of nutrients, and positive effects against various disorders of the gastrointestinal tract, such as high levels of cholesterol and postprandial blood glucose; oat can also modify immune response and reduce the risk of colon cancer. Oat is a cereal with relatively low agrotechnical requirements compared to other cereals, but constant exposure to various environmental stresses reduces the quality and quantity of yield. There is a continuing need for further improvement of this species with respect to the aforementioned benefits. Currently, the approach to improving oat production capacity involves not only the study of qualitative and quantitative traits, but also their inheritance, as well as resistance to fungal, bacterial, viral, and nematode diseases that reduce yield and its quality. Moreover, the increasing climate changes detected in recent years are forcing breeders to produce new, fertile, and resistant cultivars using biotechnology and genetic engineering.

This Special Issue of Plants will provide a selection of studies related to various aspects of oat molecular genetics and breeding in combination with obtaining high-yielding plants, resistant to abiotic and biotic stresses

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.

Oat (Avena sativa L.) cultivars ‘Bingo’ and ‘Chwat’ were used to compare the embryogenesis competence of another culture. Despite the embryo-like structures obtained from both tested cultivars, only ‘Chwat’ produced green plantlets, which confirmed the cultivar dependency. ‘Chwat’ produced the highest number of embryo-like structures and green plantlets (0.7/100 anthers and 0.1/100 anthers, respectively). The embryo-like structure formation also depended on cold pretreatment combined with Cu2+, Zn2+, or Ag+ ion supplementation, which was applied during the tiller pretreatment or added to the induction media. The highest number of embryo-like structures (2.1/100 anthers) were observed on anthers derived from the tillers kept in a 50% Hoagland medium with the addition of 10 µM of CuSO4. In turn, the induction media supplemented with the ions Cu2+, Zn2+, or Ag+ increased neither the number of embryo-like structures nor the green plantlet production compared to the control conditions. However, such ion applications turned out to be most effective when the induction medium was enriched with 25 µM of AgNO3 and left to obtain the highest number of embryo-like structures and green plantlets (0.8/100 anthers and 0.2/100 anthers, respectively). Therefore, more attention should be paid to the possibilities of adjusting the media nutrient composition, as this may be the only way to significantly increase the efficiency of this method.
