A simple and rapid method for isolating high-quality RNA from kenaf with high polysaccharide and polyphenol contents.

The extraction of high-quality RNA from kenaf is essential for genetic and molecular biology research. However, the presence of high levels of polysaccharide and polyphenol compounds in kenaf poses challenges for RNA isolation. We proposed a simplified, time-saving and cost-effective method for isolating high quantities of RNA from various kenaf tissues.

First report of root rot caused by Fusarium solani on roselle in Nanning, Guangxi, China.

Roselle (Hibiscus sabdariffa L.) is an annual herbaceous plant in the Malvaceae family with high anthocyanin and is widely cultivated in Nanning, Guangxi of China due to its economic and nutritional importance. In August 2021, a severe root rot disease with incidence of 42.

Nucleo-cytoplasmic interactions affect the 5' terminal transcription of mitochondrial genes between the isonuclear CMS line UG93A and its maintainer line UG93B of kenaf (Hibiscus cannabinus).

Gene expression and translation in plant mitochondria remain poorly understood due to the complicated transcription of its mRNA. In this study, we report the 5' and 3' RNA extremities and promoters of five mitochondrial genes, atp1, atp4, atp6, atp9, and cox3. The results reveal that four genes (atp1, atp4, atp6, and cox3) are transcribed from multiple initiation sites but with a uniform transcript at the 3' end, indicating that heterogeneity of the 5' end is a common feature in the transcription of kenaf mitochondrial genes.

Identification and fine-mapping of a genetic locus underlying soybean tolerance to SMV infections.

Soybean mosaic virus (SMV) is a major pathogen causing yield loss. Developing soybean plants tolerant or resistant to SMV is important for mitigating the adverse effects of the viral infection. However, most studies have focused on the resistance to normal SMV strains.
