First Report of Nigrospora hainanensis Causing Leaf Blight on Brachiaria Griseb in China.

Brachiaria Griseb is an important gramineous forage grown in tropical regions, and also a main grass species uses to restore grasslands in tropical and subtropical regions of China. In August 2022, symptoms of leaf blight were observed on nearly 30% of the Brachiaria forage grass in the base of the Chinese Academy of Tropical Agricultural Sciences, Hainan, China. Symptomatic leaves initially exhibited small, reddish-brown, round or oval spots on their tips, subsequently expanding in size along the leaf margin, and gradually becoming wilted and dry.

Comparative karyotype analysis of eight Cucurbitaceae crops using fluorochrome banding and 45S rDNA-FISH.

To have an insight into the karyotype variation of eight Cucurbitaceae crops including Linnaeus, 1753, Linnaeus, 1753, (Thunberg, 1794) Matsumura et Nakai, 1916, (Thunberg, 1784) Cogniaux, 1881, Linnaeus, 1753, (Linnaeus, 1753) Roemer, 1846, Lagenariasicerariavar.hispida (Thunberg, 1783) Hara, 1948 and Duchesne ex Poiret, 1819, well morphologically differentiated mitotic metaphase chromosomes were prepared using the enzymatic maceration and flame-drying method, and the chromosomal distribution of heterochromatin and 18S-5.8S-26S rRNA genes (45S rDNA) was investigated using sequential combined PI and DAPI (CPD) staining and fluorescence hybridization (FISH) with 45S rDNA probe.

Association between genetic variants in and inflammatory bowel disease risk in Caucasians: a meta-analysis and trial sequential analysis.

Objective: The published studies regarding the relationships between zinc finger 365 (ZNF365) polymorphisms and inflammatory bowel disease (IBD) risk in Caucasians have yielded conflicting results. Therefore, we performed a meta-analysis to clarify this issue.

Methods: The Electronic databases of PubMed, Web of Science, Wiley Online Library, and EMBASE were searched for eligible studies up to 31 November 2020.

Comparative molecular cytogenetic characterization of five wild species (Fabaceae).

To extend our knowledge on karyotype variation of the genus Savi, 1824, the chromosomal organization of rRNA genes and fluorochrome banding patterns of five wild species were studied. Sequential combined PI (propidium iodide) and DAPI (4',6-diamidino-2-phenylindole) (CPD) staining and fluorescence hybridization (FISH) with 5S and 45S rDNA probes were used to analyze the karyotypes of (Jacquin, 1771) Bentham, 1959, (Linnaeus, 1753) A. Richard, 1845, (Roxburgh, 1832) Ohwi & H.

[Spotting the positions of T-DNA on the genome for Magnaporthe grisea transformants and study on the mode of T-DNA insertion].

Using thermal asymmetric interlaced PCR (TAIL-PCR), 39 specifical fragments of Magnaporthe grisea genomic DNA flanked on the T-DNA were successfully amplified from 37 M. grisea transformants randomly selected from the mutants induced by T-DNA insertion in our laboratory. These fragments were sequenced and then compared by BLAST with the sequences of M.
