In plants, chemical and mechanical traits are involved in the defense against environmental stressors. case of Mimosa touch-sensitive responses through leaf-closure provide a unique form defense. While past research has shown that impacts stressors such as competition or short-term drought may cause defenses plants to increase decrease, it is unknown how interaction these influence efficiency r...
The objective of this work was to characterize nutritional parameters bee pollens from plant species occurring in a semiarid region, Picos, state Piaui, Brazil. Bee pollen samples were collected the experimental apiary Study Group on Bees Semiarid Region Piaui (GEASPI/UFPI) and subjected melissopalynological analysis determine their botanical origins, bromatological (crude protein, lipids, fibe...
Members of the genus Burkholderia (β-proteobacteria) have only recently been shown to be able to establish a nitrogen-fixing symbiosis with several legumes, which is why they are also referred to as β-rhizobia. Therefore, very little is known about the competitiveness of these species to nodulate different legume host plants. In this study, we tested the competitiveness of several Burkholderia ...
Horizontal gene transfer (HGT) is an important mode of adaptation and diversification of prokaryotes and eukaryotes and a major event underlying the emergence of bacterial pathogens and mutualists. Yet it remains unclear how complex phenotypic traits such as the ability to fix nitrogen with legumes have successfully spread over large phylogenetic distances. Here we show, using experimental evol...
AIM OF THE STUDY Evaluations of the anti-snake venom efficacy of Mimosa pudica tannin isolate (MPT) obtained from root of the plant. MATERIALS AND METHOD MPT was investigated in vitro and in vivo for its efficacy against the venom of Naja kaouthia snake. RESULTS In vitro: (1) mice injected i.p. with MPT pre-incubated with Naja kaouthia venom at concentrations as low as 0.625 mg/ml showed 10...
