Summary: The study used two marker systems to detect substantial genetic variation among different market types of carrot plants, allowing for germplasm characterization and genome relationship analysis. The genetic diversity structure within the western carrot gene pool was revealed, pointing to discrepancies within the cultivars' passport data.

Summary: In this study, FRR control strains were screened from the rhizosphere soil of A. chinensis. MH and CJ5 showed high control potential against F. oxysporum and promoted the growth and nutrient content of A. chinensis seedlings. The combined application of MH and CJ significantly reduced oxidative damage in A. chinensis roots and increased the abundance of beneficial strains. Bacillus spp. and T. harzianum can be considered as potential biocontrol agents for FRR.

Summary: Armillaria root rot is a serious threat to stone-fruit and nut crops in the main production area of the US. Developing resistant rootstocks is crucial for sustainable production. This study analyzed the molecular defense mechanisms of resistant Prunus rootstocks against Armillaria using transcriptomic analysis and identified important genes and pathways involved in resistance.

Summary: In this study, the genetic diversity, population structure, and mating type distribution of Setosphaeria turcica, the causal agent of northern corn leaf blight, were investigated in the mid-west of China. The results showed that the isolates could be categorized into two genetic groups, with low genetic differentiation and high gene flow among the four geographic populations. The distribution of mating types was balanced. These findings provide important information for developing strategies to control northern corn leaf blight caused by S. turcica in this region.

Summary: The study revealed that root rot generally increased the diversity of the pea root-associated microbiome and altered the community structure and relative abundance of key taxa. Healthy samples were associated with a higher relative abundance of Rhizobium, Olpidium and Mortierella, while diseased samples had more indicator genera and taxa exclusively detected in the diseased core microbiome.

Summary: This study analyzed the endophytic bacterial and fungal communities in roots of Phytophthora foot-rot-affected and healthy citrus trees, finding that the composition and structure of the communities were altered, with decreases in beneficial bacteria and fungi in the roots of foot-rot-affected citrus trees.

Summary: This study identified Fusarium commune as a causal agent of wilt and root rot disease in rice, characterized by long and slender monophialides, polyphialides, and abundant chlamydospores. Pathogenicity assays showed that all the isolates produced wilt and root rot symptoms, with isolate BD019R being the most virulent. It is the first report of F. commune causing wilt and root rot disease on rice.

Summary: Black root rot (BRR) is a significant disease affecting cotton and other crops, particularly in cooler regions with short growing seasons. Resistance to BRR has been identified in G. arboreum accession BM13H, which is associated with reduced hyphal growth and sporulation. Transcriptome analysis revealed that BM13H responds to infection at early time points, with few differentially expressed genes observed by day 5. Inheritance studies indicated a single semi-dominant locus conferring resistance to BRR in BM13H, which was fine mapped to a region on chromosome 1 containing potential resistance genes.

Summary: Wheat root rot disease caused by soil-borne fungal pathogens leads to significant yield losses worldwide. The relationship between rhizosphere soil fungal diversity and wheat roots is crucial in understanding the occurrence of the disease. Differences in fungal diversity were observed between healthy and diseased wheat roots at different growth stages, with soil pH, nitrogen levels, and soil density playing important roles in the occurrence of wheat root rot disease.

Summary: The research found that the causal agent of citrus tan spot, Phyllosticta citriasiana, has high genetic diversity in three pomelo production regions in southern and southeastern China. It exhibits a heterothallic mating system with two mating types and evidence for both sexual and asexual reproduction. Despite genetic differentiation between populations, long-distance gene flow was observed.

Summary: This study revealed a greater diversity of Fusarium species associated with maize sheath rot in Heilongjiang province than previously reported, with F. subglutinans, F. temperatum, F. solani, F. sporotrichioides, F. tricinctum, and F. acuminatum identified as causal agents for the first time. The population expansion of F. verticillioides was also observed.

Summary: This study used microsatellites to describe the genetic diversity and population structure of Venturia effusa, the plant-pathogenic fungus causing scab disease in pecan trees in South America. The results showed high genetic diversity in the populations, with evidence of population differentiation but no significant correlation between genetic distance and geographic distance. Both mating types were present in all orchard populations, and their frequencies followed the expected ratio. The population genetics of South American V. effusa populations shared similarities with those previously described in the United States.

Summary: This field study conducted from 2015 to 2017 demonstrates significant differences in targeted traits among cotton genotypes, indicating a wide range of genetic diversity among parent genotypes. The interaction between genotypes is highly significant for all traits, suggesting the presence of both additive and non-additive variations in gene expression. Additionally, the thirty-two cotton crosses show high yields, lint cotton production, and fiber quality, making the selection of high general combining ability (GCA) parents and high specific combining ability (SCA) crosses an effective approach for improving cotton traits and developing new varieties with excellent yield and fiber quality.
