“…Cutaneotrichosporon, present only in winter as the second most dominant genus, is analyzed to be cold-tolerant, possibly secreting lipids to alter cellular fluid composition and enhance plant frost resistance. Mrakia, exclusive to spring and the third most dominant strain, is presumed to play a significant role in assisting the plant to withstand late cold spells during the pre-sprouting phase in spring [12,114].…”

“…cloacae strain CPR5B and the endophytic fungus Penicillium citrinum strain CPL1F from the drought-resistant plant Calotropis procera. Both were found to produce indole acetic acid (IAA) and 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase, and were capable of solubilizing phosphate, thus promoting plant growth [12]. Zhang et al isolated the endophytic fungus Aspergillus ochraceus XZC-1 from Lagopsis supina, which showed significant antibacterial activity against Staphylococcus and Fusarium graminearum.…”

The seasonal changes in environmental conditions can alter the growth states of host plants, thereby affecting the living environment of endophytes and forming different endophytic communities. This study employs Illumina MiSeq next-generation sequencing to analyze the 16SrRNA and ITS rDNA of endophytes in 24 samples of Actinidia arguta stem tissues across different seasons. The results revealed a high richness and diversity of endophytes in Actinidia arguta, with significant seasonal variations in microbial community richness. This study identified 897 genera across 36 phyla for bacteria and 251 genera across 8 phyla for fungi. Notably, 69 bacterial genera and 19 fungal genera significantly contributed to the differences in community structure across seasons. A distinctive feature of coexistence in the endophytic community, both specific and conservative across different seasons, was observed. The bacterial community in winter demonstrated significantly higher richness and diversity compared to the other seasons. Environmental factors likely influence the optimal timing for endophyte colonization. Solar radiation, temperature, precipitation, and relative humidity significantly impact the diversity of endophytic bacteria and fungi. In addition, seasonal variations show significant differences in the nutritional modes of fungal endophytes and the degradation, ligninolysis, and ureolysis functions of bacterial endophytes. This study elucidates the potential role of endophytes in assisting Actinidia arguta in adapting to seasonal changes and provides a theoretical basis for further exploration of functional microbial strains.

Os microrganismos endófitos são promissores no campo agrícola como potenciais estimuladores de crescimento. Assim, foi avaliado o potencial estimulador de fungos endofíticos na soja (Glycine max (L.) Merril. Inicialmente foram coletadas 12 amostras de fungos endofíticos em diversas partes de várias espécies de plantas cultivadas. Estes fungos foram isolados, identificados e cultivados e em processo de fermentação durante 72h. Após deste processo foi preparada uma concentração ao 60% para ser aplicada. Plântulas de soja previamente semeadas em potes de plástico de 500 ml contendo substrato esterilizado e sem nenhum tipo de adubação e com 7 dias de idade foram pulverizadas com 5mL da solução previamente preparada. As plântulas foram mantidas em estufa a 28°C e fotoperíodo 12 horas. Após de 8 dias desde a aplicação dos extratos foram avaliados o tamanho e o diâmetro do caule e a raiz. Posteriormente a massa fresca e seca usando uma balança de precisão foi avaliada. Os resultados evidenciaram que dos 12 fungos aplicados nas plântulas, oito incrementaram significativamente o comprimento do caule, com um maior destaque para as plantas tratadas com Purpureocillium lilacinum e Penicillium citrinum. Já o diâmetro do caule foi maior em todos os tratamentos exceto nas plantas tratadas com Penicillium citrinum. O comprimento da raiz também foi incrementado significativamente quando tratados com algumas espécies de fungos. Similarmente a massa aérea e radicular também foi incrementada dependendo dos tratamentos. Conclusivamente nossos resultados mostram o potencial uso destes fungos como bioestimuladores radiculares o de caule da soja.
