“…Currently, niche models like the Maxent (Maximum Entropy) model [37], ENFA (Ecological Niche Factor Analysis) model [38], CLIMEX (Climate Change Experiment) [39], and GARP (Genetic Algorithm for Rule-set Production) model [40] and GLMs (Generalized Linear Models) [41] are widely used to simulate and predict the appropriate areas of fungal diseases [5,[42][43][44]. The Maxent modeling approach is widely utilized among these models due to its superior predictive performance [5,45,46].

The plant pathogenic fungus Cytospora is notoriously known for causing woody plant canker diseases, resulting in substantial economic losses to biological forests and fruit trees worldwide. Despite their strong negative ecological impact, the existing and prospective distribution patterns of these plant pathogens in China, according to climate change, have received little attention. In this study, we chose three widely dispersed and seriously damaging species, namely, Cytospora chrysosperma, Cytospora mali, and Cytospora nivea, which are the most common species that damage the Juglans regia, Malus domestica, Eucalyptus, Pyrus sinkiangensis, Populus spp., and Salix spp. in China. We utilized ecological niche modeling to forecast their regional distribution in China under four climate change scenarios (present, SSP 126, SSP 370, and SSP 585). The results show that temperature-related climate factors limit the current distribution ranges of the three species. Currently, the three studied species are highly suitable for northeast, northwest, north, and southwest China. Under future climate scenarios, the distribution ranges of the three species are projected to increase, and the centers of the adequate distribution areas of the three species are expected to shift to high-latitude regions. The three species coexist in China, primarily in the northwest and north regions. The ecological niches of C. chrysosperma and C. nivea are more similar. The distribution range of C. mali can reach the warmer and wetter eastern region, whereas C. chrysosperma and C. nivea are primarily found in drought-prone areas with little rainfall. Our findings can help farmers and planners develop methods to avoid the spread of Cytospora spp. and calculate the costs of applying pesticides to reduce contamination and boost yields.

“…Recent studies have found that S. sclerotiorum can also grow endophytically in monocots, including rice, wheat, maize, barley, and oat [4][5][6]. Based on infected host plant species, bioclimatic data, and geographic locations, economic losses caused by S. sclerotiorum are substantial and can vary extremely [7,8].…”

Sclerotinia sclerotiorum (Lib.) de Bary (1884) is a fungal plant pathogen with worldwide distribution and a varying host range from different botanical families. It can cause damage to a large variety of crops such as sunflower, soybean, dry bean, canola, some vegetables, and ornamental plants. This article reports the occurrence of twig blight on the forsythia plant from the NE region of Romania. The disease was observed on Forsythia × intermedia Zab. plants from the Arboretum Park of the Iasi University of Life Sciences (IULS), located in Iasi City, Romania. Infected tissue was investigated through morphological characteristics using Sanger sequencing. Genomic DNA was extracted from the isolate obtained from naturally infected plants, and the ribosomal internal transcribed spacer region was amplified using the ITS1, ITS2, and LSU D1 and D2. Based on the results of this study, molecular and morphological data suggest that Forsythia twig blight can be caused by S. sclerotiorum. Constant monitoring of Sclerotinia sclerotiorum across multiple hosts and time intervals will reduce potential spread and future economic losses in cultivated species.

Acclimation enables plants to adapt to immediate environmental fluctuations, supporting biodiversity and ecosystem services. However, global changes are altering conditions for plant disease outbreaks, increasing the risk of infections by pathogenic fungi and oomycetes, and often undermining plant immune responses. Understanding the molecular basis of plant acclimation is crucial for predicting climate change impacts on ecosystems and improving crop resilience. Here, we investigated how Arabidopsis thaliana quantitative immune responses acclimates to daily temperature fluctuations. We analyzed responses to the fungal pathogen Sclerotinia sclerotiorum following three acclimation regimes that reflect the distribution areas of both species. Mediterranean acclimation, characterized by broad diurnal temperature amplitudes, resulted in a loss of disease resistance in three natural A. thaliana accessions. Global gene expression analyses revealed that acclimation altered nearly half of the pathogen-responsive genes, many of which were down-regulated by inoculation and associated with disease susceptibility. Phenotypic analysis of A. thaliana mutants identified novel components of quantitative disease resistance following temperate acclimation. Several of these mutants were however more resistant than wild type following Mediterranean acclimation. Notably, mutant lines in the NAC42-like transcription factor did not show a loss of resistance under Mediterranean acclimation. This resistance was linked to an acclimation-mediated switch in the repertoire of NAC42-like targets differentially regulated by inoculation. These findings reveal the rewiring of immune gene regulatory networks by acclimation and suggest new strategies to maintain plant immune function in a warming climate.
