Special Issue Information

Dear Colleagues,

Plants interact with beneficial microorganisms from their early stages of development, playing crucial roles in promoting seed germination, improving nutrient availability, enhancing water uptake, preventing phytopathogen attacks, and strengthening responses to abiotic stresses. Therefore, the screening and utilization of plant growth-promoting microorganisms are vital for sustainable horticultural production. Microorganisms can be isolated from various sources and evaluated for their plant growth-promoting potential both in vitro and in vivo. Several strategies have been proposed to manage these beneficial microorganisms, including methods that leverage microbiomes to enhance tolerance to abiotic stress and promote plant growth. In the context of current climate change, which creates increasingly challenging conditions for plant growth, there is a pressing need to identify compatible microorganisms to ensure the growth and yield of horticultural crops. This Special Issue aims to focus on plant–microbe interactions and invites studies that employ a combination of approaches to explore the diversity, adaptation, ecological roles, and benefits of plant-associated microbes in horticultural production under both 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 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. Horticulturae 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 2200 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.

Abstract
Given the global economic importance of citrus and growing threats from climate change and soil degradation, this study investigated how arbuscular mycorrhizal (AM) fungi (Funneliformis mosseae, Fm, formerly Glomus mosseae; Diversispora versiformis, Dv, formerly Glomus versiforme) and endophytic [...] Read more.
Given the global economic importance of citrus and growing threats from climate change and soil degradation, this study investigated how arbuscular mycorrhizal (AM) fungi (Funneliformis mosseae, Fm, formerly Glomus mosseae; Diversispora versiformis, Dv, formerly Glomus versiforme) and endophytic fungus Serendipita indica (Si, formerly Piriformospora indica) differentially enhance spring shoot growth, nutrient acquisition, phytohormone profiles, and expression patterns of Fe/Mg transporter genes in two citrus cultivars (‘Beni-Madonna’ and ‘Lane Late’). Si achieved higher root colonization than AM fungi (Fm/Dv) in both cultivars, with peak colonization observed in September. Fungal inoculation differentially enhanced spring shoot growth and leaf gas exchange, with Fm and Dv demonstrating cultivar-specific effects, while Si consistently increased shoot number across cultivars but showed limited gas exchange influence in ‘Lane Late’. In ‘Beni-Madonna’, AM fungi broadly enhanced auxins/cytokinins, while Si specifically increased indole-3-acetic acid and dihydrozeatin but reduced N6-isopentenyladenine; ‘Lane Late’ showed comprehensive hormone upregulation by all fungi except Si’s dihydrozeatin suppression. AM fungi enhanced Ca, Mg, and Mn in ‘Beni-Madonna’ and P, S, Zn, and B in ‘Lane Late’, while Si increased Fe and Zn in the former and P, S, and B in the latter. Fungal symbionts differentially regulated Fe/Mg transporter genes in a cultivar-specific manner. In ‘Beni-Madonna’, Fm upregulated key Fe transporters (CsFRO1, CsHA1, and CsIRT1) while Si broadly enhanced all Fe transporters, correlating with increased leaf Fe levels; Fm specifically induced CsMGT2 and CsMGT8, showing strong association with Mg accumulation. ‘Lane Late’ exhibited distinct responses, with Si comprehensively activating both Fe (CsFRO1, CsHA1-2, and CsIRT1-2) and Mg (CsMGT6/8) transporter genes, while Dv showing minimal effects. These findings demonstrate that fungal symbionts differentially regulate citrus growth and nutrient homeostasis in a cultivar-dependent manner, highlighting the importance of host genotype-specific fungal partnerships for sustainable citrus production.
