Phytotoxic Substance with Allelopathic Activity in [PDF]

Natural Product Communications, 2015
The grass Brachiaria decumbens becomes naturalized and quickly dominant in non-native areas. It was hypothesized that phytotoxic substances of plants may contribute to the domination and invasion of the plants. However, no potent phytotoxic substance has

Spontaneous poisoning by Brachiaria decumbens in goats [PDF]

Pesquisa Veterinaria Brasileira, 2016
Abstract: An outbreak of Brachiaria decumbens poisoning in goats in the state of Mato Grosso do Sul, Brazil, is described. Out of a herd of about 1,000 goats, seven goats died after showing photosensitivity (3 out 7 goats) and icterus (4/7). Other clinical signs included lethargy, dehydration and weight loss (7/7).

Molecular and Structural Characterization of Foam Proteins from Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae) Nymphs Reveals Adaptive Features and Potential Targets for Pest Control. [PDF]

Arch Insect Biochem Physiol
Nymphs of Mahanarva spectabilis produce a protective foam that supports survival, reduces plant damage, and contributes to adult population establishment. Proteomic profiling combined with protein sequencing and structural modeling revealed foam proteins enriched in functional domains associated with environmental resilience.

Hepatogenous Photosensitization in Steer by Brachiaria decumbens [PDF]

Acta Scientiae Veterinariae, 2021
Background: Although the etiology of hepatogenous photosensitization has not yet been fully elucidated, it is known that hepatotoxic substances (saponins) present in grasses of the genus Brachiaria spp. are responsible for intoxication of several species, causing great economic losses in the whole world.

Saponins and Sapogenins from Brachiaria decumbens Stapf [PDF]

Journal of the Brazilian Chemical Society, 2002
Four steroidal saponins and three sapogenins were identified from aerial parts of Brachiaria decumbens. Their structures were established by chemical and spectroscopic means (¹H and 13C NMR, HMBC, HMQC) as 3beta-methoxy-lanost-9(11)-ene (1), diosgenin (2a), yamogenin (2b), 3-O-beta-D-glucopyranosyl-24(S)-ethyl-22E -dihydrocholesterol (3a), 3-O-beta-D ...

CHLOROPHYLL FLUORESCENCE IN Brachiaria decumbens AND Brachiaria ruziziensis SUBMITTED TO HERBICIDES [PDF]

Planta Daninha, 2017
ABSTRACT Different doses of herbicides can promote a differentiated physiological response in grasses of the same genus. This study has been proposed in order to evaluate physiological responses of B. ruziziensis and B. decumbens submitted to glyphosate and fluazifop-p-butyl. Treatments were distributed in a 2 x 6 factorial design with five repetitions,
