Special Issue Information

Dear Colleagues,

As the majority of living organisms, plants face a continuous battle against adverse environmental conditions, including increasing soil salinity, heat waves and water scarcity, which are increasingly being observed worldwide in the context of the ongoing climate changes. Plant cells are full of inorga­nic ions and low-molecular-mass organic molecules, and expend considerable amounts of energy and resources in incorporating or synthesizing these solutes. The transport of such solutes across cell membranes is of the utmost importance to re-establish and maintain ion and cellular homeostasis in response to biotic and abiotic stress. Additionally, plant-protective molecules like secondary metabolites may be produced in plant tissues in response to extreme climate conditions or after pathogen infection. Furthermore, encouraging reports have shown that the exogenous application of protective compounds like glycine betaine, kaolin based particle film or silicon (Si) may promote stress tolerance in several crops.

This Special Issue aims to attract contributions on breakthrough discoveries concerning plant solute homeostasis systems in response to stress and stress mitigation approaches. This deepened knowledge will pave the way for the improvement of plant productivity through the optimization of agricultural practices or through biotechnological approaches, including genetic engineering, and traditional plant breeding.

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. Molecules 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 1800 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.

Botrytis cinerea is a necrotrophic fungal phytopathogen with devastating effects on many Vitis genotypes. Here, a screening of 81 Vitis genotypes for leaf resistance to B. cinerea revealed two highly resistant (HR), twelve resistant (R), twenty-five susceptible (S) and forty-two highly susceptible (HS) genotypes. We focused on the HR genotype, ‘Zi Qiu’ (Vitis davidii), and the HS genotype ‘Riesling’ (V. vinifera), to elucidate mechanisms of host resistance and susceptibility against B. cinerea, using detached leaf assays. These involved a comparison of fungal growth, reactive oxygen species (ROS) responses, jasmonic acid (JA) levels, and changes in the anti-oxidative system between the two genotypes after inoculation with B. cinerea. Our results indicated that the high-level resistance of ‘Zi Qiu’ can be attributed to insignificant fungal development, low ROS production, timely elevation of anti-oxidative functions, and high JA levels. Moreover, severe fungal infection of ‘Riesling’ and sustained ROS production coincided with relatively unchanged anti-oxidative activity, as well as low JA levels. This study provides insights into B. cinerea infection in grape, which can be valuable for breeders by providing information for selecting suitable germplasm with enhanced disease resistance.
