Special Issue Information

Dear Colleagues,

Due to their sessile nature, plants are exposed to a multitude of environmental factors that adversely affect their growth and development. Decades of research have been dedicated to elucidating the effects of abiotic stresses on plant physiology; however, despite the significant insight that has been gained on plant responses to single environmental stressors, we do not have a complete understanding of the inter- and intra-plant variability that plants exhibit under different conditions of stress, depending on the duration, the severity, and the growth stage at which the stress occurs. Furthermore, climatic projections warn that the extremity and frequency of abiotic stresses are projected to increase to unprecedented levels in the future; however, plant physiological and metabolic responses under such conditions have been poorly characterized. Adding to that complexity, abiotic stresses rarely, if ever, occur in isolation under field conditions, and the effects of combined or consecutive stresses on plant physiology and metabolism have been rather unexplored. Additionally, plant physiological functions after stress conditions have been relieved have received considerably less attention compared with responses under stress conditions. This Special Issue is intended to present research on 1) the effects of single (heat, cold, drought, flooding, atmospheric pollutants, nutrient deficiencies) and combined abiotic stresses on plant physiology and metabolism at the tissue, organ, and whole plant level and 2) plant physiological and metabolic responses after stress alleviation at the tissue, organ, and whole plant level.

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 papers will be 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. Agriculture 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 1000 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.

The Effects of Root Temperature on Growth, Physiology, and Accumulation of Bioactive Compounds of Agastache rugosa

Plants respond to root temperature stresses by producing antioxidants as a defense mechanism. Since a number of these are phytochemicals with enhancing effects on human health, we examined the effects of 4 root-zone temperature (RZT) treatments (10, 20, 28, and 36 °C) on plant growth and the main bioactive compound concentrations in each organ of Agastache rugosa plants. We aimed to determine the optimal RZT treatment to increase bioactive compound concentrations with no deleterious effects on plant growth. Four-week-old seedlings were grown in a plant factory for 32 days. Nine plant growth parameters, namely, shoot and root fresh weights, stem and root lengths, leaf length and leaf width, leaf area, and shoot and root dry weights were significantly decreased at 10 and 36 °C compared with other treatments. A similar pattern was observed for the chlorophyll content and leaf gas exchange parameters. Of all the RZT treatments, RZT at 28 °C produced the significantly greatest accumulation of two major bioactive compounds, namely, rosmarinic acid (RA) and tilianin contents per the A. rugosa plant, and had no adverse effects on the overall growth of A. rugosa. This supports the use of 28 °C RZT to successfully improve the bioactive compounds with no adverse influence on plant growth or yield. Full article
