“…According to Tanvere et al. (2023) also reported that the combined application of salicylic acid and Pseudomonas putida significantly increased plant growth in canola plants under drought stress. It suggests that salicylic acid and bioagents that protect the plant against stress and contribute to plant growth may have potential in the control of phytoplasma diseases.…”

Increasing incidences of phytoplasma infestations in Almond trees warrants the better management approach to prevent yield losses. Disease management rely on identification of the pathogen based on molecular profiling. The present study aimed, to identify the phytoplasma agent in almond trees and to measure the biochemical responses it causes in the host. Direct and Nested PCRs performed using phytoplasma specific primer pairs 16S rRNA, detected the presence of phytoplasma agent in symptomatic trees but not in symptomless trees. Phylogeny based on the sequence analysis revealed that the infecting agent was closely related to ‘Candidatus Phytoplasma phoenicium’ (16SrIX‐B subgroup). Then the study was carried out to determine the responses of physiological and biochemical mechanisms in almond trees infected with phytoplasma. Total chlorophyll and protein contents of infected almond trees were lower compared to healthy control, on the other hand, the levels of catalase and peroxidase activity increased in infected trees. Higher levels of stress‐related metabolites such as proline (20.53–39.23 μmol/g), phenol (3.00–4.44 mg GAE/g), salicylic (94.96–138.22 ng SA/mg protein) and jasmonic acid (965.86–1465.10 ng JA/mg protein) were observed in infected trees compared to asymptomatic trees, respectively in healthy and infected trees. The results showed that the Ca. P. phoenicium, which was detected for the first time in Türkiye, was able to change the physiological and biochemical mechanisms. The pathogenic agent could possess a potential danger in almond production areas. It is crucially important that this agent should be considered in certification programs.

“…The use of rhamnolipid resulted in the dominance of Pseudomonas and Chryseobacterium as bacterial populations, and the dominance of Meyerozyma, Zasmidium, Vishniacozyma, Penicillium, and Aspergillus as fungal populations. Pseudomonas has the potential to act as a plant biostimulant and improve drought resistance in rapeseed [39,40]. Studies have shown that Chryseobacterium in the rice phyllosphere has a role in suppressing rice blast disease [41], and Chryseobacterium isolated from potato tissue can act as a biocontrol agent against bacterial wilt disease [42].…”

Background: Small peptides play a crucial role in plant growth and adaptation to the environment. Exogenous small peptides are often applied together with surfactants as foliar fertilizers, but the impact of small peptides and surfactants on the tea phyllosphere microbiome remains unknown. Results: In this study, we investigated the effects of small peptides and different surfactants on the tea phyllosphere microbiome using 16s and ITS sequencing. Our results showed that the use of small peptides reduced the bacterial diversity of the tea phyllosphere microbiome and increased the fungal diversity, while the use of surfactants had a suppressive effect on both bacterial and fungal diversity. Furthermore, the addition of rhamnolipid to small peptides significantly improved the tea phyllosphere microbiome community structure, making beneficial microorganisms such as Pseudomonas, Chryseobacterium, Meyerozyma, and Vishniacozyma dominant populations. Conclusion: Our study suggests that the combined use of small peptides and surfactants can significantly modify the tea phyllosphere microbiome community structure, particularly for beneficial microorganisms closely related to tea plant health. Thus, this study provides a reference for the application of small peptides and surfactants in agricultural production, which can be used to regulate the phyllosphere microbiome community in tea plant management.

“…When soybeans were inoculated with a mutant strain that had a deficiency in trehalose synthesis, they showed reduced nodules and biomass compared to those inoculated with the wild-type strain under drought conditions [173]. The coinoculation of Pseudomonas putida and SA resulted in an increased production of osmolytes, phenols, and flavonoids while reducing damage caused by drought stress [174].…”

Oil crops are the second most cultivated economic crop in the world after food crops, and they are an important source of both edible and industrial oil. The growth of oil crops is limited by biotic and abiotic stresses, which hinder their yield and quality. Among all the agronomic measures, plant growth promoting bacteria (PGPB) play a crucial role in improving the yield, quality, and adaptability of oil crops. In this review, we considered the recent research on the sources of beneficial bacteria and their interactions with and influences on host plants, with a focus on summarizing the important roles and molecular mechanisms of PGPB in promoting growth and resisting biotic and abiotic stresses in oil crops. Finally, we outlined the current opportunities and challenges of microbial strategies for the improvement of the yield, quality, and adaptability of oil crops, providing a theoretical basis for the future use of microbial inoculants in these crops.
