Terrestrial Establishment of Strangler Figs in Burned Tropical Peat Swamp Forests, Sumatra, Indonesia

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Strangler figs (Ficus spp.) typically establish as epiphytes on host trees. Here we document abundant terrestrial establishment of strangler figs in burned tropical peat‐swamp forests of Sumatra, Indonesia. Given their abundance, flexible establishment mode, and role as keystone species supporting frugivore communities, naturally regenerating strangler

Genetic Variation and Population Structure of Oryza glaberrima and Development of a Mini-Core Collection Using DArTseq

Frontiers in Plant Science, 2017
The sequence variation present in accessions conserved in genebanks can best be used in plant improvement when it is properly characterized and published. Using low cost and high density single nucleotide polymorphism (SNP) assays, the genetic diversity,

Resistance to rice root-knot nematode Meloidogyne graminicola identified in Oryza longistaminata and O. glaberrima

Nematology, 1999
Abstract Accessions of Oryza longistaminata and O. glaberrima, two rice species from Africa, and O. sativa were screened to identify sources of resistance to Meloidogyne graminicola. An initial population of 6000 J2/plant was inoculated to cuttings of the African rice species and 5-day-old seedlings of O. sativa. Root

Genetic Improvement of Iron Toxicity Tolerance in Rice-Progress, Challenges and Prospects in West Africa

Plant Production Science, 2015
In sub-Saharan Africa, the demand for higher rice production continues to grow rapidly. Although there is a huge potential for increasing rice production through expansion of the rice cultivation area in wetlands, iron (Fe) toxicity tends to occur and ...

Antimicrobial properties of the methanol leaf extract of Vernonia glaberrima Welw. Ex O. Hoffm (Asteraceae)

African Journal of Pharmacy and Pharmacology, 2015
The emergence of multi-drug resistant microbes necessitates a continuous search for newer, effective antimicrobial agents. The crude methanol leaf extract of Vernonia glaberrima was screened for its antimicrobial activity against pathogenic microorganisms including Methicillin resistant Staphylococcus aureus, Vancomycin resistant enterococci, Listeria ...

Grain Protein Content of Interspecific Progenies Derivedfrom the Cross of African Rice (Oryza glaberrima Steud.) and Asian Rice (Oryza sativa L.)

Plant Production Science, 2006
The protein contents of the grain of 50 interspecific progenies developed from the cross between WAB56-104, an Oryza sativa variety, and CG 14, an Oryza glaberrima line, were investigated. In contrast to the higher protein content of O. glaberrima than O.
