    Abstract: Although the forests of the Congo basin are known for their richness in species, there are still several works in assessing their biomass. Mindful of this fact, the present study performed in the Dja biosphere reserve aims to assess plant diversity and carbon stocks. 10 transects of 5 ha each were assessed. 9,293 individuals divided into 47 familie...

    Abstract: Ground orchid (Spathoglottis plicata) cultivated have many constraints such as the appearance of fusarium wilt disease caused by Fusarium oxysporum (Fo). A resistant S. plicata plantlet to Fo has been initiated by in vitro selection on Vacin and Went (VW) medium containing fusaric acid (FA) at concentrations of 10 ppm, 20 ppm, 30 ppm, and 40 ppm, c...

    Abstract: The diphtheria toxin A subunit gene (DT-A) from Corynebacterium diphtheriae inhibits protein synthesis in eukaryotes. In this study, toxicity of the DT-A gene was evaluated by a transgenic approach in tobacco and rice. The DT-A gene was cloned under transcriptional control of the CaMV 35S promoter and transformed into tobacco. Similarly, CaMV 35S a... Show More
