A study describes the potential impact of climate change on the distribution of Senegalia senegal (Acacia senegal), predicting severe reductions in the genetically diverse Zambesian and Southern populations and an expansion of the Sudano-Sahelian group with low genetic diversity. Lyam 2022

A study conducted in northeastern Ethiopia found Acacia seyal to be one of the most important tree and shrub species at lower and middle elevations used by farmers for household economy and soil fertility. Muche 2022

Comparative analysis of soil under Acacia senegal (Senegalia senegal) plantations and adjacent grasslands in Sudan found soil nutrient concentrations (nitrogen, phosphorus and potassium) relatively low, strongly related to soil organic matter content, and with little difference between the plantations and grasslands. Abaker 2018

Analysis of microsatellite markers found the genetic diversity of Senegalia senegal in West Africa higher than previously reported, while its overall distribution strongly correlated with several soil and climatic factors such as soil organic carbon and mean temperature of the driest quarter, providing the basis for the study's predictions of the species' response to climate change. Lyam 2018

A study analyzed the threats faced by 16 food tree species, including Acacia senegal, in Burkina Faso, predicting serious threats from climate change, overexploitation, and cotton production for all the species, with suggestions such as assisted regeneration and replanting in areas with suitable habitats in the future. Erratum in Correction: Spatially explicit multi-threat assessment of food tree species in Burkina Faso: A fine-scale approach. PLOS ONE Staff. PLoS One. 2018 Jan 2;13(1):e0190760. doi: 10.1371/journal.pone.0190760. eCollection 2018. Gaisberger 2017

Rhizobial inoculation of 13-year-old Senegalia senegal (syn. Acacia senegal) trees with a microbial cocktail significantly increased the percentage of gum arabic-producing trees and yield per tree, positively correlated with soil microbial biomass. Fall 2016

Correlations between various growth-related traits of Acacia senegal seedlings suggest strong genetic control, thus making them potential markers for the selection of genotypes most suitable for the afforestation of arid regions. Pancholy 2015

Acacia seyal seedlings grown in soil obtained from Jatropha curcas cultivation sites, a popular agrofuel in Senegal, unexpectedly developed root nodules mostly containing nitrogen-fixing nifH gene sequences belonging to the Bradyrhizobium genus with a very small number of genotypes. Dieng 2015

A survey of 80 villagers in a gum arabic (Acacia senegal)-producing region of Sudan identified factors that limit gum production in the area, also revealing gum harvesting as a supplementary source of income, especially during the off-farm season. Koli 2013

A study elucidated factors affecting somatic embryogenesis from the immature cotyledon of the gum arabic (Acacia senegal) tree. Rathore 2012

A study provides evidence that Acacia seyal could play an important role in the improvement of reafforestation process due to its "promiscuous" relationship with Mesorhizobium spp. strains isolated from different agro-ecological zones in Senegal. Diouf 2010

A study provides phenotypical and genotypical characterization of root-nodulating bacteria associated with Acacia senegal trees growing in the dry land area of Senegal with results suggesting adaptability of natural rhizobial populations to ecological environmental stress. Fall 2008

A study describes an in vitro propagation technique of Acacia senegal, providing up to four rooted plants from each uninodal explant. Badji 1993

An article describes the effects of desertification on gum arabic production in Sudan, as well as attempts to remedy the impact. Tinker 1978
