Última Effects of Corynespora cassiicola on Lantana camara Planta Daninha Passos,J.L.; Barbosa,L.C.A.; Demuner,A.J.; Barreto,R.W.; King-Diaz,B.; Lotina-Hennsen,B.. The present study combines the examination of toxins produced by C. cassiicola and the effects of the fungus colonization on L. camara. C. cassiicola was cultivated on solid media and the crude extracts CAE and CE were produced. Both extracts were submitted to a seed germination and growth assay utilizing Physalis ixocarpa, Trifolium alexandrinum, Lolium multiflorum and Amaranthus hypochodriacus. The effect of the extracts on the ATP-synthesis in isolated spinach chloroplasts was also tested. Bioassay guided chromatographic fractionation identified the most active extract (CAE). From this extract ergosta-4,6,8(14),22-tetraen-3-one (C1) and fatty acids were isolated. The C1 compound reduce ATP synthesis in isolated spinach chloroplasts. The interference of...

Ano: 2010 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-83582010000200001 Foliar anatomy of the species Lantana camara and L. radula (Verbenaceae) Planta Daninha Passos,J.L.; Meira,R.M.S.A.; Barbosa,L.C.A.. The species Lantana camara, commonly used as ornamental, has spread worldwide becoming one of the world's most important weeds. To develop new methods of control of this plant, it is essential to distinguish it from other species of the same genus, and this is usually accomplished through taxonomic studies of fertile samples. Considering the similarity between L. camara and L. radula, and the consequent difficulty in distinguishing one from the other when only sterile samples are available, this work aimed to investigate the use of the anatomical characteristics of the leaves of both species as tools for supporting correct classification. The leaves of L. camara and L. radula were anatomically examined by light microscopy and scanning electron microscopy....
