Micropropagation in Horticultural Crops

Dear Colleagues,

In vitro propagation has significant progress potential for the micropropagation of horticultural crops using semi-solid gelled and liquid media, although clonal fidelity is a significant concern in micropropagation for commercial production. In vitro culture-derived variation (somaclonal variation) can be genetic (heritable) or epigenetic (non-heritable) or a combination of both. Genetic variation may be due to mutation at chromosome and/or gene levels, and epigenetic variation can arise through the insertion, excision, or activation of transposable elements, DNA methylation, and/or segregation of pre-existing chimera tissue. This Special Issue of Agronomy focuses on the various innovative micropropagation techniques used for in vitro culture of horticultural crops and the study of micropropagules for the assessment of genetic fidelity and heritable (genetic) and non-heritable (epigenetic) variations in micropropagules of horticulturalcerops.

For this Special Issue, papers in the areas of micropropagation and somaclonal variation including, but not limited to, shoot regeneration and proliferation, somatic embryogenesis, protoplast isolation, culture and fusion, clonal fidelity, and genetic and epigenetic variations in micropropagated horticultural plants are welcome.

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. Agronomy is an international peer-reviewed open access monthly 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 2600 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.
