Emergence of false smut (RFS) in rice agroecosystems is causing significant yield losses due to its direct impact on grains. To assess the factors associated with host-pathogen interaction, maximum entropy principle used identify bioclimatic variables behind geo-spatial distribution patterns RFS. Bioclimatic ecological significance, derived from monthly temperature and precipitation, such as precipitation wettest month, mean warmest quarter seasonality are linked occurrence disease. These three identified strongest predictors RFS contributing 47.81 %, 26.63 % 12.43 respectively. Seasonal variability have played a limiting factor for Temperature plays crucial role pathogen growth development (mycelial growth, sclerotial germination infection) exerts influences disease distribution. Spatial pattern intensity, well number sclerotia/panicle development, infection suitability, suggest that response daily during booting stage development. Number favourable days composed [f(T) > 20] rainfall (>5 mm) noted be proportional incidence (infected grains/panicle). validated through ground truth data correspondence month (June-Sep). The rainfall-induced monocyclic process at known crop implicated evaluation management options effective fungicides available.

Verbena officinalis is an important medicinal plant widely used in traditional Chinese medicine for the treatment of rheumatism, insomnia, and liver gallbladder diseases. Its resources primarily rely on wild populations, which are insufficient to meet increasing market demand. Furthermore, climate change exacerbates uncertainty its distribution range. This study employs optimized MaxEnt model predict potential V. under current future scenarios China. Based 445 effective occurrence records 90 environmental variables (covering climatic, soil, topographic factors), selected key influencing through correlation analysis variable contribution rates, parameters improve prediction accuracy (AUC = 0.934). Results showed that, conditions, total suitable habitat area 2.06 × 10 6 km 2 , accounting 21.39% China’s land area, mainly distributed central, eastern, southern The minimum temperature coldest month (bio_6, rate 72.8%) was identified as factor distribution, while November precipitation (prec_11) annual range (bio_7) also played roles. Under (SSP1-2.6 SSP5-8.5), shows overall trend, reaching a maximum 2070s high-emission scenario (an increase 3.6 5 compared distribution). Expansion observed northern high-latitude regions. geometric centroid areas demonstrated significant northward shift, reflecting adaptive expansion response warming climates. highlights impact provides scientific evidence conservation, cultivation planning, sustainable development context change.

ABSTRACT Frangipani ( Plumeria spp.: Apocynaceae) is a small ornamental tree native to Mexico, susceptible significant diseases such as anthracnose and foliar blight in hot, dry environments. Understanding the diversity of pathogens responsible for these crucial developing effective disease management strategies. This study aimed identify diseases. In February 2020 2021, symptoms were observed on frangipani plants recreational areas Morelos Sinaloa, Mexico. Isolations from diseased leaf tissue resulted recovery 12 Colletotrichum isolates P. rubra 18 Alternaria obtusa . After morphotype grouping, representative isolate each group was identified by morphology phylogenetic reconstruction (ITS, act , gapdh rpb2 tef1 ) karstii siamense destruens burnsii For pathogenicity testing, conidial suspension sprayed onto leaves 90‐day‐old plants, while control with sterile distilled water. All inoculated fungi pathogenic, reproducing characteristic disease, remained symptomless. The recovered symptomatic morphologically identical fungi, fulfilling Koch's postulates. first report A. causing C. These findings contribute valuable insights
