BUDDLEJA DAVIDII (SCROPHULARIACEAE) ESPECIE INVASORA NUEVA PARA LA FLORA ADVENTICIA DE LA ARGENTINA

Abstract Butterfly bush (Buddleja davidii) is classified as invasive in several parts of the United States. Two experiments were conducted to evaluate the effectiveness of four herbicides and two application methods on postemergence butterfly bush control. The four herbicides included: Roundup (glyphosate), Aquamaster (glyphosate), Garlon (triclopyr), and Arsenal (imazapyr). Application methods included spraying foliage with a CO2 backpack sprayer, and applying herbicide concentrate to recently cut stems (cut-stump method). Plants were treated in September with the maximum labeled rate for each herbicide. Cut-stump rates were determined such that the same amount of active ingredient was applied as in the spray treatments. Applications were made to plants several months after planting to simulate control of small recently germinated plants, and again to plants over 1 year old to simulate control of larger and more established plants. Summarizing results over both plant sizes and from two repetitions of the experiment, Roundup and Aquamaster provided higher levels of control compared to Garlon and Arsenal early in the experiment. Cut-stump applications provided more rapid control than spray applications. Despite differences in control when evaluated several weeks after application, all treated plants were dead when evaluated the following spring.

Carotenoid Pathway

Abstract Crocetin biosynthesis in Buddleja davidii flowers proceeds through a zeaxanthin cleavage pathway catalyzed by two carotenoid cleavage dioxygenases (BdCCD4.1 and BdCCD4.3), followed by oxidation and glucosylation reactions that lead to the production of crocins. We isolated and analyzed the expression of 12 genes from the carotenoid pathway in B. davidii flowers and identified four candidate genes involved in the biosynthesis of crocins (BdALDH, BdUGT74BC1, BdUGT74BC2, and BdUGT94AA3). In addition, we characterized the profile of crocins and their carotenoid precursors, following their accumulation during flower development. Overall, seven different crocins, crocetin, and picrocrocin were identified in this study. The accumulation of these apocarotenoids parallels tissue development, reaching the highest concentration when the flower is fully open. Notably, the pathway was regulated mainly at the transcript level, with expression patterns of a large group of carotenoid precursor and apocarotenoid genes (BdPSY2, BdPDS2, BdZDS, BdLCY2, BdBCH, BdALDH, and BdUGT Genes) mimicking the accumulation of crocins. Finally, we used comparative correlation network analysis to study how the synthesis of these valuable apocarotenoids diverges among B. davidii, Gardenia jasminoides, and Crocus sativus, highlighting distinctive differences which could be the basis of the differential accumulation of crocins in the three species.

Abstract A description is provided for Peronospora hariotii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Buddleja davidii cv. White Profusion, B. globosa and cultivars, especially cv. Lemon Ball. DISEASE: Downy mildew of Buddleja. This is a disease of nursery stock and there are no reports of the fungus infecting mature plants. Young plants 1-2 ft. high bear conspicuous brown lesions on their leaves. These begin as a yellow area on the upper surface which soon turns brown and brittle. Leaves affected in this way usually drop off. The leading shoot and terminal bud may also die. The down, which develops on the lower surface of infected leaves, is pale to medium brown depending on age and weather conditions. GEOGRAPHICAL DISTRIBUTION: Europe (Britain, France). TRANSMISSION: Not known.
