This study was conducted to investigate the bioactive and chemical components, ethnobotany and pharmacological activities of Calotropis procera leaves and fruits with a focus on its antimicrobial effect on isolated bacteria. To prepare the plant extract, methanol was used as the solvent, for evaluation of the bioactive compounds and their concentration in the plant extracts hence, qualitative and quantitative phytochemical analysis was conducted respectively. The GCMS analysis was conducted for further determination of the chemical composition of the plant parts. The antimicrobial impacts of the plant leaves and fruits methanolic extracts were carried out against assay organisms which were bacterial group and they include Standard and clinical strains of Bacillus subtilis ATCC 6633, Bacillus subtilis clinical, Staphylococcus aureus β-haemolytic strain and clinical, Staphylococcus aureus, Salmonella typhi clinical, Klebsiella pneumonia clinical, Escherichia coli and Proteus sp. Clinical strain. This study showed the presences of some phytochemical compounds such as tannin, alkaloid, saponin, flavonoid etc. in C. procera leaves and fruits at varying concentration. The GCMS analysis revealed that Pentadecanoic acid and n-Hexadecanoic acid were detected in both leaves and fruits of C. procera extracts. Furthermore, methanolic extract of the plant leaves had antibacterial effect potency towards Bacillus subtilis ATCC 6633, while the fruit extract had no antibacterial effect against the assay organism.

Erythrophleum suaveolens is locally described as a poisonous plant, but still been used in the control of pest of cereals. It exhibits antifungal, medicinal properties and the seeds have essential oil. The aim of this study is to investigate the prevalence, and usage of this plant in the Federal Capital Territory (FCT), Abuja, Nigeria. Questionnaires were used in gathering information to study the plant with respect to its uses, parts used, preparation and prevalence. Regional survey studies show an abundance of plants in parts of Abuja. The study also shows that the leave part of the plant is largely used for pesticidal purpose. The correlation between the perceptions of the respondents on the use of the plant were statistically significant, (χ2 [2; n = 100] = 25.93; p< 0.05), with a strong strength of association (Phi=0.509, Cramer’s V=0.509, p<0.05). The correlation of the perceptions of the respondents on the plant prevalence were also found to be statistically significant, (χ2 [2; n = 100] = 44.444; p< 0.05), and the strength of relationship between the variables were strong (Phi=0.667, Cramer’s V=0.667, p<0.05). This study conclusively shows the plants prevalence in FCT as a plant for pest management

This study aims to evaluate the phytotoxicity effect in Erythrophleum suaveolens leaves extracts on germination and growth of Oba 98, Oba super 6, Samaz 52 and Sanaz 37 maize seeds varieties obtained from Abuja, Nigeria. The maize seeds were subjected to treatment with exposure to methanol and water extract of E. suaveolens in different concentrations of 100, 10 and 1% respectively. A control group was set up without treatment. Both treated and untreated seeds were planted in petri-dish in the laboratory and their germination and growth were monitored for 8 days. Germination was only experienced with the 1% methanol of the E. Suaveolens with a mean germination percentage of 33.33±28.87, mean radical length (mm) of 24.67±24.03 and mean plumule length (mm) of 13.33±12.22 treated Oba98 seeds. All other maize seeds germination was inhibited by the extracts used for the treatment. The control group germination and growth were not inhibited. The extract treatment shows a significant relationship with the three (3) parameters; germination percentage, radical and plumule length with F(6, 84) =7.833, 9.688 and 8.567 respectively at p<0.05. E. suaveolens extract demonstrated allelopathic and phytotoxicity characteristics by inhibiting the germination and growth of maize seeds after 8 days of planting. This study clearly shows that E. suaveolens demonstrated allelopathic characteristics by inhibiting the germination and growth of maize seeds after 8 days of planting. Therefore, it could be said to have a phytotoxic effect on Zea mays.

The D2 protein of the PhotosystemII(PSII) reaction center complex is encoded by the chloroplast gene psbD. To gain a better understanding of the adaptive radiation of core leptosporangiate ferns in low ̄light environmentsꎬ we sequenced psbD in twelve species and collected eight published sequences to represent extant ferns in order level. We then evaluated the selection pressure of D2 protein based on ω values ( nonsynonymous synonymous substitution ratio). The results of statistical tests based on different models indicated that most sites and branches were under strong negative selectionꎬ but tree ferns exhibited a slower evolutionary rate and higher ω value compared with other ferns. Co ̄evolution analysis based on different approaches showed that the D2 ̄R168ꎬ D2 ̄H245 and D2 ̄M272 of tree ferns were involved in the same co ̄evolution network.
