Special Issue Information

Dear Colleagues,

This Special Issue explores the intricate relationships within plant genomics and genetics, secondary metabolism, plant pharmacology, developmental biology, physiology, and pathology, particularly in the context of responses to biotic and abiotic stresses.  It also highlights important areas such as plant growth and development, phytohormone signaling, photosynthesis, respiration, gene editing technologies, environmental remediation, molecular nutrition, and functional activity. Additionally, the impact of microorganisms and pathogens on plants is a critical aspect of biotic stress, influencing plant health and development through various mechanisms, including pathogen infection, changes in secondary metabolites, regulation of phytohormones, and modulation of gene expression.

Submitted papers should present innovative research findings, new regulatory models, and the latest insights related to plant signaling, development, and stress responses.  The focus of this Special Issue will be on the identification of new genes, enzymes, or metabolites, the discovery of novel signaling pathways, the interactions among phytohormones, and the characterization of gene regulation networks that contribute to plant growth specificity, alongside the interplay between environmental stressors, microbial interactions, and biochemical responses.

Volume I of the Special Issue Plant Responses to Biotic and Abiotic Stresses.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Abstract
In protected cultivation, light intensity, spectral quality, red/far-red ratio, photoperiod and diel fluctuation can alter the belowground biological environment by modifying carbon allocation, root architecture, root exudation, nutrient acquisition, immune tone and rhizosphere physicochemistry.

In protected cultivation, light intensity, spectral quality, red/far-red ratio, photoperiod and diel fluctuation can alter the belowground biological environment by modifying carbon allocation, root architecture, root exudation, nutrient acquisition, immune tone and rhizosphere physicochemistry. Direct community-level evidence in vegetables remains sparse, but targeted experiments on bacterial colonization, arbuscular mycorrhizal symbiosis, beneficial fungi and root pathogens show that light can condition specific plant–microbe interactions. This review develops a molecular framework for light–root–microbiome interactions in protected vegetable crops and distinguishes direct community evidence, targeted colonization or symbiosis evidence, crop-specific indirect evidence and mechanistic analogues. We synthesize how photoreceptors and PIF-, HY5-, hormone- and immunity-related pathways regulate root niche construction, while also considering direct microbial photoreception. Experimental examples include tomato rhizosphere responses to shading, R:FR-dependent colonization by Serratia plymuthica, phyB–HY5–strigolactone control of tomato mycorrhization, light-intensity effects on lettuce–AMF interactions, spectrum-dependent Trichoderma harzianum colonization and light sensing by Ralstonia pseudosolanacearum. The evidence supports the view that light acts as a conditional regulator whose effects depend on crop genotype, microbial partner, substrate, nutrient status and developmental stage. Progress will require factorial lighting experiments coupled with exudomics, stable-isotope tracing, absolute microbial quantification, isolate genomics, synthetic communities and pathogen-challenge assays.
