Systemic Toxicity of L-Mimosine in Rabbits: A Non-Rodent Model for Safety Assessment. [PDF]

J Appl Toxicol
ABSTRACT L‐mimosine is a non‐protein amino acid primarily found in the Mimosoideae subfamily, with high concentrations in Leucaena leucocephala and Mimosa pudica. These plants are widely used in both human and animal nutrition, as well as in phytotherapeutic applications. While the toxic effects of L‐mimosine have been extensively studied in ruminants,

Legume genome structures and histories inferred from Cercis canadensis and Chamaecrista fasciculata genomes. [PDF]

Plant J
SUMMARY The legume family originated ca. 60–65 million years ago and soon diversified into at least six lineages (now extant subfamilies). The signal of whole genome duplications (WGD) is apparent in species sampled from all six subfamilies. The early diversification has posed difficulties for resolving the legume backbone structure and the timing of ...

The frequency and importance of polyploidy in tropical rainforest tree radiations [PDF]

New Phytol
Summary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...

Long-term vegetation changes in elephant-related areas of concern in Kruger National Park, South Africa. [PDF]

Ecol Appl
Abstract African elephants, whether alone or in combination with other environmental factors such as floods, droughts, fire, and other herbivores, have significant impacts on large savanna trees, often contributing to declines over time. However, their effects on woody vegetation in general remain less well understood.

The Complete Chloroplast Genome of Tornillo (<i>Cedrelinga cateniformis</i> Ducke 1922, Fabaceae). [PDF]

Ecol Evol
Tornillo (Cedrelinga cateniformis) is a tropical tree from the Fabaceae family, valued as a substitute for overexploited timber species. This study presents the first complete chloroplast genome sequencing of Tornillo, revealing a 176,700 bp structure with 138 genes and confirming its phylogenetic placement within the Ingeae tribe.

Mapping Biodiversity Through Time and Space: Patterns and Drivers of Fabaceae Collection in Mozambique. [PDF]

Ecol Evol
Africa's plant diversity remains under‐documented due to limited sampling, expertise and resources, with type specimens offering a historical baseline to evaluate taxonomic effort and biodiversity knowledge. Using generalised linear modelling, we show that collection patterns in Mozambique were shaped by elevation, slope, land cover and accessibility ...

Beyond conservation: the landscape of chloroplast genome rearrangements in angiosperms. [PDF]

New Phytol
Summary Chloroplast genomes (plastomes) have long been considered structurally conserved, but recent sequencing efforts have uncovered pervasive rearrangements that challenge this assumption. This review catalogues the main types of plastome modifications: large and small inversions; insertions and deletions (indels); gene and intron losses; horizontal

A new spin on chemotaxonomy: Using non-proteogenic amino acids as a test case. [PDF]

Appl Plant Sci
Abstract Premise Specialized metabolites serve various roles for plants and humans. Unlike core metabolites, specialized metabolites are restricted to certain plant lineages; thus, in addition to their ecological functions, specialized metabolites can serve as diagnostic markers of plant lineages.

Differential gene reactions reveal drought response strategies in African acacias. [PDF]

Plant J
SUMMARY Drought tolerance involves a complex series of genetic reactions that expand over time as water stress intensifies. We investigated gene expression reactions over 43 days of drought stress in two widespread African savanna trees: the umbrella acacia (Vachellia tortilis) and the splendid thorn acacia (Vachellia robusta).
