Special Issue Information

Dear Colleagues,

Understanding the processes that accompany or facilitate the origin and diversification of species has always been of great interest to evolutionary biologists. Genetic and ecological plant adaptation is a central component of many speciation-with-gene-flow models. This Special Issue on “Orchid Research: From Genomics to Diversity Conservation” in Plants aims to contribute with research papers as well as reviews on the wide range of topics related to orchid biology. We welcome papers concerning:

  • The genetic basis of the evolution of novel traits in response to environmental changes and how this can subsequently cause species isolation;
  • The mechanisms of pre-/postzygotic reproductive isolation;
  • The analysis of hybrid development and the implications of species differentiation in terms of adaptation to a novel environment;
  • Allopolyploidy as an important mode of orchid speciation;
  • Population genomics approach to study orchid adaptation and speciation;
  • The role of pollinators in the formation of new species and the establishment and maintenance of reproductive barriers between species;
  • Symbiosis with soil fungi as a key factor in determining orchids’ distribution and ecological adaptability.

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.

Orchids are fascinating for many reasons: their reproductive strategies, their pollination systems and the various morphological adaptations they have evolved, including the presence of pollen grains agglomerated into two masses, called pollinia, which form a structure known as a pollinarium. After withdrawal from a flower, the pollinarium undergoes a bending movement such that the pollen masses become correctly orientated to strike the stigma. We evaluated the duration of pollinator visits to inflorescences and the effects of temperature on pollinaria reconfiguration in eight orchid species in order to analyze the effects of increasing air temperature on the changes in bending time, and thus on geitonogamy levels. The impact of temperature on insect behavior was not assessed because our priority was to understand the effects of temperature on the process of pollinaria reconfiguration. All the examined species showed natural reconfiguration times that were 1.7–3.0 times longer than the pollinator residency times. A higher temperature showed a reduction in bending time regardless of the species tested. However, the bending time was never shorter than the residence time of the insects on the flower. Our data showed that high temperatures had a limited effect on the pollinarium reconfiguration time, thus indicating that high temperatures had a limited effect on folding compared to the effect that it had on the viability of the pollen.
