infection status and molecular diversity in the species of tribe Tagiadini Mabille, 1878 (Lepidoptera: Hesperiidae) collected in China.

, one of the most ubiquitous heritable symbionts in lepidopteran insects, can cause mitochondrial introgression in related host species. We recently found mito-nuclear discordance in the Lepidopteran tribe Tagiadini Mabille 1878 from which has not been reported. In this study, we found that 13 of the 46 species of Tagiadini species tested were positive for Overall, 14% (15/110) of Tagiadini specimens were infected with and nine new STs were found from 15 isolates.

CBSX2 is required for the efficient oxidation of chloroplast redox-regulated enzymes in darkness.

Thiol/disulfide-based redox regulation in plant chloroplasts is essential for controlling the activity of target proteins in response to light signals. One of the examples of such a role in chloroplasts is the activity of the chloroplast ATP synthase (CFCF), which is regulated by the redox state of the CFγ subunit and involves two cysteines in its central domain. To investigate the mechanism underlying the oxidation of CFγ and other chloroplast redox-regulated enzymes in the dark, we characterized the Arabidopsis mutant, which was isolated based on its altered NPQ (non-photochemical quenching) induction upon illumination.

NDH-1L with a truncated NdhM subunit is unstable under stress conditions in cyanobacteria.

Cyanobacterial NdhM, an oxygenic photosynthesis-specific NDH-1 subunit, has been found to be essential for the formation of a large complex of NDH-1 (NDH-1L). The cryo-electron microscopic (cryo-EM) structure of NdhM from showed that the N-terminus of NdhM contains three β-sheets, while two α-helixes are present in the middle and C-terminal part of NdhM. Here, we obtained a mutant of the unicellular cyanobacterium 6803 expressing a C-terminal truncated NdhM subunit designated NdhMΔC.

Taxon-dependent effects of dispersal limitation versus environmental filters on bryophyte assemblages-Multiple perspective studies in land-bridge islands.

To explore the taxon-dependent contribution of dispersal limitation versus environmental filters to bryophyte assemblages. We investigated bryophytes and six environmental variables on 168 islands in the Thousand Island Lake,China. We compared the observed beta diversity with the expected values based on six null models (EE, EF, FE, FF, PE, and PF), detected the partial correlation of beta diversity with geographical distances.

Antihypertensive effect of giant embryo brown rice and pre-germinated giant embryo brown rice on spontaneously hypertensive rats.

"Shangshida NO.5" is a giant embryo mutant resulting from giant embryo gene () dysfunction in "Chao2-10" rice. Here, we compared the antihypertensive effects of "Chao2-10" brown rice (C2-10), "Shangshida NO.
