Special Issue Information

Dear Colleagues,

Plants are endowed with the exceptional ability to regulate their growth depending on the environment by fine-tuning the activity of meristematic cells that originate different organs during their lifetime. In this manner, plants can modulate their developmental strategies according to seasonal changes in day length, temperature, and humidity. The so-called developmental plasticity has also influenced the adaptation of plants to new territories and their survival in stressful situations. Thus, the interaction between a plant and the habitat determines not only its final architecture but also its lifespan.

In flowering plants, the transition from vegetative to reproductive growth and the onset of flower development are critical to ensure the propagation of the species. These developmental stages are influenced by both predictable changes in external conditions (such as photoperiod) and unpredictable events related to climate change (heat waves, flooding, drought, etc.). Lamentably, fluctuations in environmental conditions are changing the ecological niches of several wild species and threatening the seed production of major crop species. Given the increasing impact of climate change on plant biodiversity and food security, dissecting the signal transduction pathways underlying plant response to abiotic stresses and identifying those genetic determinants controlling adaptive traits are key to maximizing plant fitness in the wild, and guarantee reproductive success in the field.

This Special Issue of Plants will encompass research articles and reviews focusing on regulatory mechanisms that mediate the development of reproductive structures in response to environmental limitations related to climate change in a wide range of angiosperms, from model species to crops and wild plants.

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.

Hazelnuts have recently gathered tremendous attention due to the expansion of the confectionary industry. However, the sourced cultivars fail to perform in initial phase of cultivation as they enter bare survival mode due to changes in climatic zones, for example, Southern Ontario, where the climate is continental, as opposed to the milder climate in Europe and Turkey. Indoleamines have been shown to counter abiotic stress and modulate vegetative and reproductive development of plants. Here, we examined the effect of indoleamines on the flowering response of the dormant stem cuttings of sourced hazelnut cultivars in controlled environment chambers. The stem cuttings were exposed to sudden summer-like conditions (abiotic stress) and the female flower development was assessed in relation to endogenous indoleamine titers. The sourced cultivars responded well to serotonin treatment by producing more flowers compared to the controls or other treatments. The probability of buds resulting in female flowers was highest in the middle region of the stem cuttings. It is interesting to note that the tryptamine titers of the locally adapted, and N-acetyl serotonin titers of native hazelnut cultivars, provided the best explanation for adaptation to the stress environment. Titers of both compounds were compromised in the sourced cultivars which resorted mostly to serotonin concentrations to counter the stress. The indoleamines tool kit identified in this study could be deployed in assessing cultivars for stress adaptation attributes. Full article
