Catingueira (Poincianella pyramidalis Tul. L. P. Queiroz) is an endemic species of the Caatinga, with great economic potential. Research on the development of this species under conditions of water restriction, common in the Northeastern semi-arid region, is still scarce. This study evaluated the...

Plants from Fabaceae family have several secondary metabolites and high biological potential. The subfamily Papilionoideae (Fabaceae) has 28 tribes, of which Dalbergieae comprises 49 genera and 1325 species. Isoflavonoids are chemotaxonomic markers of Papilionoideae and have important biological...

In semi-arid regions, water deficit occurs for long periods, but the adaptation mechanisms developed by endemic species are little known. The objective of this study was to determine the tolerance of Luetzelburguia auriculata (Allemão) Ducke seedlings to water stress regarding germination and...

Millettia Wight & Arn. is a heterogeneous genus within the tribe Millettieae (Leguminosae) and has long been used as a repository to accommodate all undistinctive species of the tribe with elastically dehiscent pods. Millettia sect. Podocarpae Dunn is representative of the heterogeneous genus. This ...

Photoprotection is a plant functional mechanism to prevent photooxidative damage by excess light. This is most important when carbon assimilation is limited by drought, and as such, it entails a trade-off between carbon assimilation vs stress avoidance. The ecological adaptation of plants to local...

In tropical dry forests, both the dry and the short rainy seasons have become increasingly irregular. This study replicated these conditions to investigate the effects of two water deficit cycles on Cenostigma microphyllum seedlings. Impacts were assessed by measuring growth traits, water...

The Chemical study of methanolic extract of the seeds from Erythrophleum ivorense led to the isolation of one original cassane diterpenoid (1) along with six known cassane diterpenoids (2-7). In addition, the known compounds (2-7) are isolated for the first time in E. ivorense. Their structures...

Enhanced drought, more frequent rainfall events and increased inter-annual variability of precipitation are the main trends of climate expected for the Mediterranean. Drought is one of the most important stressors for plants and significantly impacts plant communities causing changes in plant...

Twenty compounds were obtained from Glycyrrhiza glabra L., which were divided as fatty alcohols (1 and 5), sterols (2, 4 and 8), triterpenes (3, 6 and 7), flavones (9, 12-15), coumarins (10, 11, 19 and 20) and stilbenes (16-18). The chemotaxonomic significance of G. glabra and the other species...

Brachypterum was highly supported as a distinct genus from Derris within the tribe Millettieae by recent molecular and mophological evidence. Brachypterum pseudorobustum (basionym: Derris pseudorobusta) and Derris robusta var. assamica were originally described on fruiting collections from...
