Identifying ecological distribution responses to climate change is pivotal for preserving biodiversity. Ilex macrocarpa, a deciduous tree of the Aquifoliaceae family, has considerable and medicinal benefits. This study investigated impact on potential I. macrocarpa using MaxEnt modeling GIS analysis. We analyzed 562 occurrence records against 19 bioclimatic variables, subsequently refined 7 key predictors through Pearson correlation analysis (|r| ≤ 0.75). The model demonstrated high predictive accuracy (AUC = 0.902 ± 0.010). Annual precipitation (67.9% contribution) minimum temperature coldest month (18.4% emerged as primary determinants distribution. Currently, suitable habitats occupy 252.97 × 104 km2 (26.35%) total land area China, with highly areas (72.82 km2) predominantly found in southern China. Under future scenarios, substantial shifts are projected: SSP126 shows 21.7% reduction by 2050, followed 9.1% recovery 2090; SSP245 indicates 13.4% 2050 minimal subsequent change; SSP585 demonstrates most severe impact, 32.0% 2090. Habitat centroid reveals significant northeastward under (116.23 km 2090), variable movements SSP245, southwestern displacement (143.23 2090). These findings suggest differential across implications conservation planning management strategies.

Decoding Pecan’s Fungal Foe: A Genomic Insight into Colletotrichum plurivorum Isolate W-6

Journal of Fungi, Journal Year: 2025, Volume and Issue: 11(3), P. 203 - 203

Pecan (Carya illinoinensis) is a world-renowned nut crop that highly favored by consumers for its high content of healthy nutrients. For long time, anthracnose has severely threatened the yield and quality pecan, causing significant economic losses to global pecan industry. Here, we report 54.57-Mb gapless chromosome-level assembly pathogenic ascomycetes Colletotrichum plurivorum isolate W-6 from plantations in Southeast China. Six 12 chromosomes contain, at least, telomeric repeats (CCCTAA)n or (TTAGGG)n one end. A total 14,343 protein-coding genes were predicted. Pathogenicity- virulence-related annotations revealed 137 4558 associated with TCDB, PHI, Cyt_P450, DFVF, effector, secretome databases, respectively. comparative analysis W-6, together 51 other strains, reveled 13 unique Orchidearum complex which belongs, highlighting major facilitator superfamily transporters. The detailed analyses MFS transporters secondary metabolite gene clusters led identification protein structure two key virulence factor candidates DHA1 subclass, prlG azaK, reported as efflux antibiotics fungi. further functional investigation identified here potentially provide important resources better understanding biology lifestyle pave way designing more efficient strategies control plantations.
