Special Issue Information

Dear Colleagues,

Plant-microbe interactions can be beneficial or detrimental for either the host or micro-organism. Beneficial microbes such as mycorrhizal fungi and rhizobia associate with roots and provide plants with mineral nutrients and fixed nitrogen, respectively, in exchange for carbon. Plant growth-promoting rhizobacteria have been known to impact plants growth and development. By contrast, plant diseases, caused by a vast number of pathogens (viruses, bacteria, oomycetes, fungi, and nematodes), are responsible for dramatic crop yield loss and pose a severe threat to the income of rural families, as well as global food security. Due to spatial and temporal variations in pathogen populations, their control is relatively tricky. Therefore, to combat the loss, the development of effective strategies to control the diseases should be considered where appropriate. In recent years, host-plant resistance or the development of resistant cultivars has been sought as an ecologically and environmentally sound way to cope with crop diseases.

In this Special Issue, we invite the submission of original research articles, scientific reports, communications, and review articles that address the progress and current understanding of different aspects of plant-microbe interaction. Multidisciplinary approaches that can describe the physiology, biochemistry, evolution, function, and regulation of plants and microbial symbiosis and plants immune system are welcome.

This Special Issue focuses on cutting-edge knowledge on beneficial plant and micro-organisms interactions, plant defense mechanisms and plant immune system evolution and function, obtained from the application of physiological principles, genetics, and genomics, as well as bioinformatics approaches. Additionally, a specific overview of plant-microbe interactions, including microbe recognition, symbiosis genes, plant resistance genes, and pathogen effectors proteins, will be considered.

With this Special Issue, we aim to provide an international platform for a broad audience of academics, researchers, policymakers, and industries to discuss interdisciplinary research and practices in the field of plant-microbe interaction.

This Special Issue highlights recent advances in the understanding of mechanisms of plant and microbes’ symbiosis, plant defense response, and covers the interdisciplinary area related to plant-microbe interaction, delving into different aspects of physiology, Phyto-biochemistry, genetics, and genomics. On this basis, the Issue will usefully supplement currently available related literature.

Plant diseases are one of the main factors responsible for food loss in the world, and 20–40% of such loss is caused by pathogenic infections. Botrytis cinerea is the most widely studied necrotrophic phytopathogenic fungus. It is responsible for incalculable economic losses due to the large number of host plants affected. Today, B. cinerea is controlled mainly by synthetic fungicides whose frequent application increases risk of resistance, thus making them unsustainable in terms of the environment and human health. In the search for new alternatives for the biocontrol of this pathogen, the use of endophytic microorganisms and their metabolites has gained momentum in recent years. In this work, we isolated endophytic bacteria from Zea mays cultivated in Colombia. Several strains of Bacillus subtilis, isolated and characterized in this work, exhibited growth inhibition against B. cinerea of more than 40% in in vitro cultures. These strains were characterized by studying several of their biochemical properties, such as production of lipopeptides, potassium solubilization, proteolytic and amylolytic capacity, production of siderophores, biofilm assays, and so on. We also analyzed: (i) its capacity to promote maize growth (Zea mays) in vivo, and (ii) its capacity to biocontrol B. cinerea during in vivo infection in plants (Phaseolus vulgaris). Full article

Wheat grains are usually low in essential micronutrients. In resolving the problem of grain micronutritional quality, microbe-based technologies, including bacterial endophytes, seem to be promising. Thus, we aimed to (1) isolate and identify grain endophytic bacteria from selected spring wheat varieties (bread Oksamyt myronivs’kyi, Struna myronivs’ka, Dubravka, and emmer Holikovs’ka), which were all grown in field conditions with low bioavailability of microelements, and (2) evaluate the relationship between endophytes’ abilities to synthesize auxins and the concentration of Fe, Zn, and Cu in grains. The calculated biological accumulation factor (BAF) allowed for comparing the varietal ability to uptake and transport micronutrients to the grains. For the first time, bacterial endophytes were isolated from grains of emmer wheat T. turgidum subsp. dicoccum. Generally, the 12 different isolates identified in the four varieties belonged to the genera Staphylococcus, Pantoea, Sphingobium, Bacillus, Kosakonia, and Micrococcus (NCBI accession numbers: MT302194—MT302204, MT312840). All the studied strains were able to synthesize the indole-related compounds (IRCs; max: 16.57 µg∙mL−1) detected using the Salkowski reagent. The IRCs produced by the bacterial genera Pantoea spp. and Bacillus spp. isolated from high-yielding Oksamyt myronivs’kyi and Holikovs’ka grains may be considered as one of the determinants of the yield of wheat and its nutritional characteristics.

Begomovirus has become a potential threat to the agriculture sector. It causes significant losses to several economically important crops. Given this considerable loss, the development of tools to study viral genomes and function is needed. Infectious clones approaches and applications have allowed the direct exploitation of virus genomes. Infectious clones of DNA viruses are the critical instrument for functional characterization of the notable and newly discovered virus. Understanding of structure and composition of viruses has contributed to the evolution of molecular plant pathology. Therefore, this review provides extensive guidelines on the strategy to construct infectious clones of Begomovirus. Also, this technique’s impacts and benefits in controlling and understanding the Begomovirus infection will be discussed. Full article

Phytoplasmas that are associated with fruit crops, vegetables, cereal and oilseed crops, trees, ornamental, and weeds are increasing at an alarming rate in the Middle East. Up to now, fourteen 16Sr groups of phytoplasma have been identified in association with more than 164 plant species in this region. Peanut witches’ broom phytoplasma strains (16SrII) are the prevalent group, especially in the south of Iran and Gulf states, and have been found to be associated with 81 host plant species. In addition, phytoplasmas belonging to the 16SrVI, 16SrIX, and 16SrXII groups have been frequently reported from a wide range of crops. On the other hand, phytoplasmas belonging to 16SrIV, 16SrV, 16SrX, 16SrXI, 16SrXIV, and 16SrXXIX groups have limited geographical distribution and host range. Twenty-two insect vectors have been reported as putative phytoplasma vectors in the Middle East, of which Orosius albicinctus can transmit diverse phytoplasma strains. Almond witches’ broom, tomato big bud, lime witches’ broom, and alfalfa witches’ broom are known as the most destructive diseases. The review summarizes phytoplasma diseases in the Middle East, with specific emphasis on the occurrence, host range, and transmission of the most common phytoplasma groups. Full article
