  Euphorbia tithymaloidus is a shrub having a range of activities like anti-inflammatory, antioxidant, anti-malarial, anti-tuberculosis, antifungal, antibacterial, antidaibetic and wound healing etc., but the anthelminthic activity of this plant is still under consideration. In this study carried out the phytochemical and anthelminthic activity of Euphorbia tithymaloidus in order to estimate its potential in treating the intestinal worms. The in vitro anthelmintic activity was performed on ethanolic leaf extract using adult earthworms (Pheretima posthuma). The standard drug used was albendazole in the concentration of 15-60 mg mL–1 to note the paralysis time and death time. The result of the study showed that the ethanolic leaf extract shows the presence of certain phytoconstituents like flavonoids, carbohydrates, steroids and alkaloids. The reaction time was noted as paralysis time and death time for all the concentrations and compared with standard albendazole. The extract exhibited remarkable activity at a concentration of 45 mg mL–1 as compared to standard drug albendazole within a shorter time span of less than 10 min.

  Microbes play a vital role in ecosystem stability. Here, microbes-Acacia association is discussed with particular reference to Arbuscular Mycorrhizal Fungi (AMF) which help in the establishment of crop-plants, especially in arid and semi-arid areas. The association helps to restore the structural composition of soil from the hazardous impact of agrochemicals, increase resistance against various pathogenic attack as well as several abiotic stresses. Further, a comparative account of microbes found in the rhizosphere of Acacia is illustrated. Among these, Rhizobia, Acetobacter, Bradyrhizobium, Bacillus, Pseudomonas and Trichoderma were described in detail. All these microbes can be regarded as Plant Growth Promoting Rhizospheric Microbes (PGPM), some of PGPM are Phosphate Solubilizing Microbe (PSM). Both of them help AMF for infecting mycorrhizal hyphae inside the plant cell. Overall, microbes can be used as biofertilizers along with other organic compounds, that can compensate for the nutrient's availability.

  Members of genus Acacia comprises of trees used as fuelwood, timber and fodder. Moreover, some parts of plants are also used for their therapeutic properties. The development and applications of breeding and biotechnological tools are advancing at a significantly fast rate. Molecular markers and genomics offer vital information with regard to the inherited variation. The aim of this study to complied and discussed the developments in molecular maker technology, genomics and genetic engineering concerning genus Acacia. Overall, this information will be useful to gain awareness about the crucial trees in the genus Acacia from breeding and a biotechnological perspective.
