Summary: In this study, a ddPCR assay was developed to detect and quantify V. nonalfalfae and V. albo-atrum, two pathogenic fungi causing Verticillium wilt. The performance of ddPCR was compared with qPCR, and ddPCR showed similar detection sensitivity, enhanced positive rate for low-abundance fungi, and superior diagnostic performance on field tissues. The quantification results of ddPCR were generally higher than qPCR, potentially due to differing amplification efficiencies. Overall, ddPCR method enables sensitive detection, accurate quantification, and improved precision for evaluating disease progression and enacting effective disease control.

Summary: Highly disturbed forests in the eastern United States are reflective of their past land use, and their management and restoration efforts are complicated by nonnative invasive plants. Vertical non-alfalfa has been found to be an effective tool for controlling the invasive Ailanthus altissima, with no observable effects on native flora. The study highlights the importance of native biocontrols in suppressing invasive plants.

Summary: Soil-borne pathogens like Verticillium species invade the roots of various plants, leading to significant increases in amino acid concentrations in stems, petioles, and leaflets of infected tomato plants. The vascular environment prior to visual symptoms emergence is of particular focus in this study. Amino acid concentrations in infected plants show substantial increases, especially in stems, petioles, and leaflets.

Summary: Tree of Heaven, an invasive species, has negative impacts on natural ecosystems and human infrastructure. Previous studies have identified a strain of fungus that is highly effective against the tree without negative effects on other plants. This study focuses on the non-target effects of this strain on susceptible agricultural crops.

Summary: Verticillium species are plant pathogens that cause wilt diseases in dicotyledon plants and crops worldwide. This study sequenced the genome of Verticillium dahliae isolated from Ailanthus altissima in Italy and identified candidate genes related to pathogenicity. The newly sequenced genome provides a valuable resource for future research on Verticillium genetics, biology, and control of A. altissima.

Summary: Since the 1950s, the invasive species tree of heaven (Ailanthus altissima) has been spreading in forests in southern Switzerland and is now a concern in northern Switzerland as well. This study used a forest gap model to simulate the long-term dynamics of managed and unmanaged forest stands under current and future climate conditions. The results suggest that although A. altissima will increase its presence in the short term, it will not dominate in the long term, except possibly in drought-prone sites with strong climate change.

Summary: Species of Alternaria are serious plant pathogens causing major losses on crops. A. atra, previously known as Ulocladium atrum, can also be used as a biocontrol agent. The high-quality reference genome assembly and annotation provided in this study can be a valuable resource for studying evolution in the Alternaria genus.

Summary: The study showed that pectin lyase can enhance cotton resistance to Verticillium wilt and induce cell apoptosis of the V. dahliae strain Vd080. Pectin lyase affects various cellular processes in the Vd080 strain, leading to ER stress and ultimately cell apoptosis. These findings suggest that pectin lyase could be a potential biocontrol agent for managing Verticillium wilt in cotton.

Summary: This study evaluated the effect of alfalfa cultivars and ages on Verticillium wilt caused by Verticillium alfalfae. The results showed that Galaxie Max cultivar had the lowest incidence of disease symptoms and a lower rate of infection compared to Danon VNS cultivar. Additionally, an increase in the age of alfalfa plants contributed to the occurrence and development of Verticillium wilt.

Summary: Cotton is a widely grown crop due to its economic value. Verticillium wilt, caused by a pathogen called Verticillium dahliae, is a devastating disease that affects cotton crops, leading to yield losses and lower fiber quality. Developing genetically engineered cotton varieties with resistance to Verticillium wilt is an effective strategy, but there are challenges due to the lack of resistance gene resources. Understanding the molecular mechanisms of the interaction between V. dahliae and cotton is crucial in identifying genes related to disease resistance.

Summary: Lettuce is an economically important vegetable in the United States, with a majority of production in the Salinas Valley of California. While resistance genes against race 1 have been identified, resistance against race 2 remains challenging. Research reveals that resistance in lettuce against race 2 is polygenic with a significant genotype by environment interaction.

Summary: The V. dahliae genome encodes a family of six xylanases, with VdXyn4 being the only enzyme that degrades the plant cell wall and contributes to the virulence of the pathogen. VdXyn4 displays cytotoxic activity and induces necrosis in host plants during late infection stages, playing a crucial intracellular role. This cytotoxic activity is likely conserved in other enzyme families in plant vascular pathogens, suggesting its importance for pathogen colonization.

Summary: This review systematically discusses the roles of the secretome of Verticillium dahliae in vascular occlusion and modulation of plant defence responses, highlighting its role in inducing Verticillium wilt. By manipulating plant defences and hormone levels, the secretome colludes with plant defence responses to modulate wilting symptoms, bridging historical concepts of both toxin production and vascular occlusion as the cause of Verticillium wilt.

Summary: Verticillium wilt, caused by Verticillium dahliae, is a major cause of yield losses in cotton. Despite this, current cultivars of cotton remain highly susceptible to Verticillium wilt. To better understand the genetic basis for resistance, the genome of a wilt-resistant cotton cultivar, Zhongzhimian No. 2, was sequenced and assembled using multiple technologies. This genomic resource will aid in understanding the genetic features related to high yield and resistance to Verticillium wilt.

Summary: Type 2C protein phosphatases play important roles in various biological processes in eukaryotes. This study identified several homologs of these phosphatases in Verticillium dahliae, with VdPtc3 being the most versatile and involved in key processes such as conidium development and pathogenicity. Furthermore, VdPtc3 interacts with VdAtg1, which modulates melanin and microsclerotium formation.
