BREAKDOWN OF SEED DORMANCY IN Canavalia brasiliensis

, 2007
Canavalia brasiliensis has a great potential as green manure in Brazilian Savanna. The species gives nitrogen to subsequent crops and produces excellent dry matter. On the other side, even under suitable environment conditions, several seeds don’t germinate due to the impermeable seed coat. This trial aimed to identify different treatments for dormancy

Lectin from Canavalia brasiliensis (ConBr) protects hippocampal slices against glutamate neurotoxicity in a manner dependent of PI3K/Akt pathway

Neurochemistry International, 2013
The excitotoxicity induced by excessive activation of the glutamatergic neurotransmission pathway is involved in several neuropathologies. In this sense, molecules that prevent the release of glutamate or the excessive activation of its receptors can be useful in preventing the neuronal cell death observed in these diseases.
