Transgenic Soybean for Production of Thermostable α-Amylase.

Alpha-amylases are crucial hydrolase enzymes which have been widely used in food, feed, fermentation, and pharmaceutical industries. Methods for low-cost production of α-amylases are highly desirable. Soybean seed, functioning as a bioreactor, offers an excellent platform for the mass production of recombinant proteins for its ability to synthesize substantial quantities of proteins.

First report of black spot on Ophiopogon japonicus caused by Alternaria alternata in Zhejiang Province, China.

Ophiopogon japonicus (Linn. f.) Ker-Gawl, a traditional Chinese medicinal plant, is widely cultured in China.

First report of root rot on Dendrobium officinale caused by Fusarium incarnatum-equiseti species complex in Zhejiang Province, China.

Dendrobium officinale Kimura et Migo is a rare and valuable Chinese herb cultivated in Zhejiang and Yunnan Provinces, China, which is known for its functions as an anti-neoplastic and for lowering the blood sugar (Cheng et al., 2019). In September and October of 2018 and 2019, symptoms of root rot on D.

Comparative Analysis of the Diversity of the Microbial Communities between Non-Fertilized and Fertilized Eggs of Brown Planthopper, Stål.

Yeast-like symbionts (YLSs), harbored in the abdominal fat body of brown planthoppers (BPHs), Stål, play an important role in the growth, development, and reproduction of their host. However, little is known about the diversity of the symbiotic fungal YLSs that are harbored in the eggs of BPHs and the difference between fertilized eggs and non-fertilized eggs. Here, we investigate the fungal community compositions of non-fertilized and fertilized eggs of BPHs and identified the YLSs in the hemolymph by qPCR.

Substantial improvement of toyocamycin production in Streptomyces diastatochromogenes by cumulative drug-resistance mutations.

Toyocamycin is a member of the nucleoside antibiotic family and has been recognized as a promising fungicide for the control of plant diseases. However, low productivity of toyocamycin remains an important bottleneck in its industrial production. Therefore, dramatic improvements of strains for overproduction of toyocamycin are of great interest in applied microbiology research.
