A new species, Adactylidium europaeum n. sp. (Acari: Acarophenacidae), is described based on phoretic females collected thorax of larvae Phlaeothrips (Thysanoptera: Phlaeothripidae) in European Russia. An updated key to the species provided.

In pyrrolizidine alkaloid-bearing Heliotropium angiospermum and H. indicum shoots exposed, in the light, to (14)C-labeled CO(2) for 44 hours, the incorporation of (14)C into 1,2-epoxy-1-hydroxymethylpyrrolizidine and retronecine amounted to 0.23 and 0.15%, respectively, of the total carbon assimilated. Treatment of the shoots with alpha-dl-difluoromethylornithine, the specific ornithine decarbo...

When tested for ornithine and arginine decarboxylases, pyrrolizidine alkaloid-bearing Senecio riddellii, S. longilobus (Compositae), and Crotalaria retusa (Leguminosae) plants exhibited only ornithine decarboxylase activity. This contrasts with previous studies of four species of pyrrolizidine alkaloid-bearing Heliotropium (Boraginaceae) in which arginine decarboxylase activity was very high re...

Background and objectives: Asarum europaeum L. is an herbal medicine belonging to the family Aristolochiaceae. The rhizome of the plant has been used for the treatment of various diseases in complementary and alternative medicine of various countries. In Iranian traditional medicine (ITM), the aqueous extract of the rhizome has been used for the improvement and enhance...

The aim of this study was to examine the environmental regulation of ̄ower initiation and subsequent development in heliotrope (Heliotropium aborescens L. cv. Marine). Five experiments were conducted, two examined whether ̄owering could be advanced by cool temperatures. The duration of cool temperature required to induce rapid ̄owering was also investigated. The ®nal three experiments examined ...

We report the draft genome sequence of Mycobacterium europaeum strain CSUR P1344, a slowly growing mycobacterium of the Mycobacterium simiae complex and opportunistic respiratory tract colonizer and pathogen. This genome of 6,152,523 bp exhibits a 68.18% G+C content, encoding 5,814 predicted proteins and 74 RNAs.

A new species, Haplothrips heliotropica, is described from Argentina causing severe damage to the leaves of Heliotropium amplexicaule (Boraginaceae), a South American plant that is now a serious weed of pastures in Australia. Observations are presented on the host specificity, seasonal population changes and overwintering of this thrips. The genus Haplothrips includes more than 230 species worl...

In extracts from the youngest leaves of Avena sativa, Hordeum vulgare, Zea Mays, Pisum sativum, Phaseolus vulgaris, Lactuca sativa, and four pyrrolizidine alkaloid-bearing species of Heliotropium, the activities of ornithine decarboxylase, close to V(max), ranged between traces and 1.5 nanomoles per hour per gram fresh weight when based on putrescine formed during incubation with labeled ornith...
