Integrative taxonomy has resolved the species status of the potentially invasive Ceratitis rosa Karsch into two separate species with distinct ecological requirements: C. rosa "lowland type" and the newly described species Ceratitis quilicii De Meyer, Mwatawala & Virgilio sp. nov. "highland type". Both species are tephritid pests threatening the production of horticultural crops in Africa and b...

UNLABELLED N,N-8-demethyl-8-amino-d-riboflavin dimethyltransferase (RosA) catalyses the final dimethylation of 8-demethyl-8-amino-d-riboflavin (AF) to the antibiotic roseoflavin (RoF) in Streptomyces davawensis. In the present study, we solved the X-ray structure of RosA, and determined the binding properties of substrates and products. Moreover, we used steady-state and rapid reaction kinetic ...

In this paper we have introduced the concept of γ-b-open sets and studied some of their properties.

Evidence was presented in a previous paper' that a hybrid substance, encountered after an antigenic character (ch4) of Streptopelia chinensis was transferred to S. risoria, resulted from the interaction of nonallelic genes. Specifically, the cha4 cellular antigen from chinensis showed no hybrid substance when present in backcross individuals that were homozygous for an independently inherited c...

Potato cultivars Katahdin (susceptible) and Rosa (resistant) were exposed to infective second-stage juveniles (J2) of Globodera rostochiensis for varying periods of time, after which root systems were washed and plants were placed in Hoagland's solution to assess J2 egression and male emergence. After transfer to liquid culture, many J2 egressed from both cultivars, but significantly more egres...
