Polyphenolic composition, antibacterial, modulator and neuroprotective activity of Tarenaya spinosa (Jacq.) Raf. (Cleomaceae)

open access: yesAsian Pacific Journal of Tropical Biomedicine, 2019
Objective: To evaluate the antibacterial activity and neuroprotective capacity of the ethanolic and aqueous extracts of Tarenaya spinosa (T. spinosa) as well as to determine and quantify some of its polyphenols by high performance liquid chromatography ...

Evolutionary processes from the perspective of flowering time diversity. [PDF]

open access: yes, 2020
Although it is well appreciated that genetic studies of flowering time regulation have led to fundamental advances in the fields of molecular and developmental biology, the ways in which genetic studies of flowering time diversity have enriched the field

Medicinal Plants Used by Tanzanians for Human Paediatric Ailments: A PRISMA‐Guided Systematic Review of Ethnomedicinal Evidence

open access: yesThe Scientific World Journal, Volume 2026, Issue 1, 2026.
Paediatric ailments (PAs) pose an increasing health and economic challenge in many low‐ and middle‐income countries. In Tanzania, over 80% of the rural population relies on traditional medicine for primary healthcare. Although documentation of medicinal plants (MPs) used to treat and manage PAs remains fragmented, this systematic review consolidates ...

First steps towards a floral structural characterization of the major rosid subclades [PDF]

open access: yes, 2018
A survey of our own comparative studies on several larger clades of rosids and over 1400 original publications on rosid flowers shows that floral structural features support to various degrees the supraordinal relationships in rosids proposed by ...

Insights into C4 metabolism from comparative deep sequencing. [PDF]

open access: yes, 2015
C4 photosynthesis suppresses the oxygenation activity of Ribulose Bisphosphate Carboxylase Oxygenase and so limits photorespiration. Although highly complex, it is estimated to have evolved in 66 plant lineages, with the vast majority lacking sequenced ...

Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics

open access: yesNew Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

Antihyperglycemic and antihyperlipidemic effects of the methanol extracts of Cleome ramosissima Parl., Barleria bispinosa (Forssk.) Vahl. and Tribulus macropterus Boiss.

open access: yesBulletin of Faculty of Pharmacy Cairo University, 2014
The antihyperglycemic and antihyperlipidemic effects of the methanolic extracts of the aerial parts of Cleome ramosissima Parl. (Cleomaceae), Barleria bispinosa (Forssk.) Vahl. (Acanthaceae) and Tribulus macropterus Boiss. (Zygophyllaceae) were evaluated

How evolution repeatedly builds complexity: a case study with C4 photosynthesis in Blepharis (Acanthaceae)

open access: yesNew Phytologist, Volume 248, Issue 4, Page 2092-2110, November 2025.
Summary With over 60 parallel origins representing evolutionary replicates, C4 photosynthesis is well‐suited for studying complex trait evolution. However, lineages with diverse C3–C4 intermediate species are scarce, leaving uncertainty in models of C4 evolution.

Vegetation spatial heterogeneity in a hyper arid Biosphere Reserve area in north Africa [PDF]

open access: yes, 2010
Ninety eight species of angiosperms belonging to 34 families were identified in the Wadi Allaqi Biosphere Reserve (S. E. Egypt): 33.7%annuals and 66.3%perennials.

Identification of shared single copy nuclear genes in Arabidopsis, Populus, Vitis and Oryza and their phylogenetic utility across various taxonomic levels [PDF]

open access: yes, 2010
Background Although the overwhelming majority of genes found in angiosperms are members of gene families, and both gene- and genome-duplication are pervasive forces in plant genomes, some genes are sufficiently distinct from all other genes in a genome ...
