The ®rst stage of leaf litter decomposition of two eucalyptus hybrids and Acacia auriculiformis was studied in laboratory experiments where the decaying leaves were leached with water. Although the litter of both the species were characterized by a high content of soluble compounds, little soluble organic matter of acacia litter was recovered in litter leachates. By contrast, soluble organic ma...
Legumes are a highly diverse angiosperm family that include many agriculturally important species. To date, 21 complete chloroplast genomes have been sequenced from legume crops confined to the Papilionoideae subfamily. Here we report the first chloroplast genome from the Mimosoideae, Acacia ligulata, and compare it to the previously sequenced legume genomes. The A. ligulata chloroplast genome ...
Many plants of the genus Acacia exude viscous gummy liquids through cuts in their bark. These exudates form clear or translucent masses when exposed to air and function to seal off the injured part of the plant thereby preventing moisture loss and entrance of plant pests or pathogens. Man has capitalized on several unique physical and rheological properties of acacia tree exudates. Gum arabica,...
This article documents the addition of 396 microsatellite marker loci to the Molecular Ecology Resources Database. Loci were developed for the following species: Anthocidaris crassispina, Aphis glycines, Argyrosomus regius, Astrocaryum sciophilum, Dasypus novemcinctus, Delomys sublineatus, Dermatemys mawii, Fundulus heteroclitus, Homalaspis plana, Jumellea rossii, Khaya senegalensis, Mugil ceph...
Stem bark of Acacia nilotica, Delbergia sissoo, Delonix regia, Polyalthia longifolia, Prosopis cineraria, and Zyziphus mauritiana, and leaves of Catharanthus roseus, Mentha arvensis, Murraya koinigii, Ocimum basilicum, Tabernaemontana divaricata, Tinospora cordifolia and Tribulus terrestris were analyzed for their total phenolic and flavonois content as well as antioxidant activity. Stem bark o...
The activities of total extracts and lupane triterpenes, isolated from the stem bark of Acacia mellifera, were evaluated against Plasmodium berghei strain ANKA in a female Swiss mouse model. Five isolated compounds and the crude extracts were evaluated for antimalarial activity and Quinine hydrochloride was used as a positive control. Only betulin and the methanolic extract produced considerabl...
Thirteen Acacia species were classified into three groups according to effective nodulation response patterns with fast- and slow-growing tropical strains of Rhizobium. The first group nodulated effectively with slow-growing, cowpea-type Rhizobium strains; the second, with fast-growing Rhizobium strains; and the third, with both fast- and slow-growing Rhizobium strains. The Rhizobium requiremen...
By repeated weekly intravenous injections of gum acacia solution in dogs over periods of 4 to 5 months, it has been possible to maintain plasma protein concentration and total circulating protein at very low levels. If sufficient numbers of such injections are given and then discontinued, plasma protein concentration will remain below the normal limits for several more months. Acacia remains in...
The structure of rhizobial communities nodulating Acacia in southeastern Australia from south Queensland to Tasmania was investigated by a molecular approach. A total of 118 isolates from nodule samples from 13 different Acacia species collected at 44 sites were characterized by small-subunit (SSU) ribosomal DNA (rDNA) PCR-restriction fragment length polymorphism analysis. Nine rhizobial genomo...
1 Herbivores may negatively impact plant populations by reducing the survival, growth and reproduction of individual plants. 2 In African savannas, browsing by large mammalian herbivores has been shown repeatedly to reduce adult survival and growth of members of the genus Acacia , the dominant trees in these systems. However, the potential costs of mammalian herbivory to Acacia reproduction are...
