Special Issue Information
Dear Colleagues,
We invite you to submit articles on the improvement of the regeneration efficiency of plants obtained from cereal microspores.
Why we consider this topic to be particularly important:
Conventional methods for raising yields are reaching their limits, and it seems that modern biotechnology could offer new promising solutions to use biological potential in plant breeding. Double haploids are an initial and essential element of published hybrid breeding strategies in cereals.
The subject matter is of great importance for the development of basic sciences, and makes it possible to increase plant breeding efficiency, thus affecting the efficiency of agriculture, including new trends such as organic and sustainable agriculture.
Research problems:
- Genetic determinants affecting in vitro regeneration.
- Improvement of regeneration conditions from induced embryos.
- Anther culture versus isolated microspore culture.
- Genetic stability of regenerants and their progeny.
Despite many years of work on inducing doubled haploids, the problem of genotypic dependence remains unsolved. Model genotypes are emerging, but the methods developed cannot be applied to any genotype.
Because of the above, we would most willingly accept texts on model genotypes that give multiple regenerations in in vitro cultures and papers describing androgenesis for a wide range of genotypes—especially in recalcitrant species, which include oats, wheat, and rye. However, we are also interested in articles dealing with the influence of external factors such as medium nutrient components, reprogramming stress, or light.
More effort is needed to fully understand the regulation of morphogenic response and develop methods for recalcitrant genotypes regeneration.

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.
