Special Issue Information
Dear Colleagues,
Flower and fruit development are processes tightly regulated by genes and phytohormones. In recent decades, an enormous wealth of information and knowledge has been obtained on the developmental processes underlying the formation and development of flowers and fruits in model plants, non-model plants, and crops. The generation, integration, and translation of gene regulatory networks driving development are important goals of many colleagues around the world. Many challenges and opportunities lie ahead of the generation of a deep understanding of regulatory networks guiding plant reproductive development. This Special Issue of Plants will highlight the function of genes, phytohormones, and gene regulatory networks in flower and fruit development.

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.

Abstract: The arabinogalactan proteins (AGPs) are described as a class of complex, highly glycosylated hydroxyproline-rich glycoproteins, participate in aspects of plant growth and development to accomplish diverse functions. In plants, flower organs had an abundant AGPs recognition toward stigma and pistil structures, whereas their abundance in female and male sexual organs was positioned to the ovule and tapetum, respectively. In this study, the spatial and temporal distribution of AGPs in C. annuum was investigated, an immunohistochemical technique using LM14 against AGPs glycan-epitopes was used to distinguish total AGPs in vegetative and reproductive organs during seedling, flowering and fruiting developmental stages. The results showed that AGPs epitopes were successfully recognized by LM14 antibody being predominant distributed in the palisade mesophilic cells during seedling suggesting an association with leaf differentiation, also, strong labelling was detected in the stigmatic surface of pistil. In ovary, an intense signal was localized in ovary-wall and embryo sac during anthesis stage, in anthers, AGPs were present in pollen-wall and tapetum during microspore cell division. These results provide insights into the cellular location and distribution of AGPs in C. annuum and indicate that action is spatio-temporal regulated, bring about evidence of their possible roles during development.
