“…They were initially fixed with 2.5% glutaraldehyde at room temperature for 2 h, followed by an overnight incubation at 4°C. Subsequently, a gradient dehydration process involved varying ethanol concentrations (30, 50, 70, 95, and 100%), before a transition to tert-butanol (Zhang et al, 2016;Mukherjee et al, 2022). Finally, the samples were freeze-dried, sprayed with gold, and observed using FESEM (Hitachi SU8010, Japan).…”

IntroductionPenicillium species exhibit a broad distribution in nature and play a crucial role in human and ecological environments.MethodsTwo Penicillium species isolated from the ancient Great Wall loess in the Mentougou District of Beijing, China, were identified and described as new species, namely, Penicillium acidogenicum and P. floccosum, based on morphological characteristics and phylogenetic analyses of multiple genes including ITS, BenA, CaM, and RPB2 genes.ResultsPhylogenetic analyses showed that both novel species formed a distinctive lineage and that they were most closely related to P. chrzaszczii and P. osmophilum, respectively.DiscussionPenicillium acidogenicum is characterized by biverticillate conidiophores that produce globose conidia and is distinguished from similar species by its capacity to grow on CYA at 30°C. Penicillium floccosum is typically recognized by its restricted growth and floccose colony texture. The description of these two new species provided additional knowledge and new insights into the ecology and distribution of Penicillium.

“…Spore suspension and plate methods can be used for the colonization of fungal endophytes in rice plants [32]. Some studies show that endophytic fungi can colonize the roots, buds, stems, leaves, sheathes, grains, and other parts of rice plants [32,42,54,60,[71][72][73]. Dark septate endophytes (DSEs) can colonize the root cortex of rice, forming structures resembling anastomoses and intracellular microsclerotia [71,74].…”

“…Therefore, reducing grain Cd and As in rice is crucial for over half of the world's population. The experimental results indicated that the plant-growthpromoting endophytic fungi (PGPEF) had a significant promoting effect on the growth of rice seedlings under cadmium stress [72]. An endophytic fungus Falciphora oryzae isolated from Oryza granulata (wild rice) was shown to decrease cadmium (Cd) accumulation in the roots [18].…”

In a long-term evolution, fungal endophytes have formed a mutually beneficial relationship with host plants. Therefore, what roles do fungal endophytes play in the growth and development of rice, one of the major food crops in the world, and agricultural production? This mini-review aims to highlight the diversity, identification, colonization, function, and mechanism of action of endophytic fungi isolated from rice tissues through a literature review; comprehensively expound the interaction mechanism between rice fungal endophytes and their hosts in stimulating the growth of rice plants and alleviating biological and abiotic stresses on plants; and contribute new ideas for rice production and a sustainable rice industry. Additionally, rice fungal endophytes, as a new resource, have broad prospects in the development of biopesticides, biocontrol agents, and new medicine.

“…isolated from the leaves of Eupatorium triplinerve effectively reduced the bioavailability of Cd 2+ during rice seedling germination through bioaccumulation and biosorption. This augmented plant growth, biomass, and pigment production under metal toxicity (Mukherjee et al, 2022). Inoculation of a consortium of such endophytic fungi to Alocasia calidora imparted resistance and growth against landfill soil contaminated with a mixture of heavy metals through the production of compatible solute, antioxidant, and heavy metal bioaccumulation (root and shoot; Hassan et al, 2022).…”

Anthropogenic activities have a critical influence on climate change that directly or indirectly impacts plant and microbial diversity on our planet. Due to climate change, there is an increase in the intensity and frequency of extreme environmental events such as temperature rise, drought, and precipitation. The increase in greenhouse gas emissions such as CO2, CH4, NOx, water vapor, increase in global temperature, and change in rainfall patterns have impacted soil–plant-microbe interactions, which poses a serious threat to food security. Microbes in the soil play an essential role in plants’ resilience to abiotic and biotic stressors. The soil microbial communities are sensitive and responsive to these stressors. Therefore, a systemic approach to climate adaptation will be needed which acknowledges the multidimensional nature of plant-microbe-environment interactions. In the last two scores of years, there has been an enhancement in the understanding of plant’s response to microbes at physiological, biochemical, and molecular levels due to the availability of techniques and tools. This review highlights some of the critical factors influencing plant-microbe interactions under stress. The association and response of microbe and plants as a result of several stresses such as temperature, salinity, metal toxicity, and greenhouse gases are also depicted. New tools to study the molecular complexity of these interactions, such as genomic and sequencing approaches, which provide researchers greater accuracy, reproducibility, and flexibility for exploring plant-microbe–environment interactions under a changing climate, are also discussed in the review, which will be helpful in the development of resistant crops/plants in present and future.
