  • Phylogenetic Position of Nigerian Species of Curcuma longa (Zingiberaceae) in the Current Infrageneric Classification

    Fountain Journal of Natural and Applied Sciences, 2024
    Curcuma longa L. (commonly known as Tumeric) is the only species of the genus Curcuma found in Nigeria. It is of great economic importance to Nigeria, Africa, Asia, and other parts of the world, where it is widely used for ornamental and medicinal purposes, and as spices in food and beverages. However, the phylogenetic placement of the turmeric plant (C. longa) in Nigeria is far from being fully resolved, hence the need for this study. The rhizomes of turmeric were collected at the Forestry Research Institute of Nigeria, Ibadan, Oyo state. Genomic DNA was extracted, followed by the amplification of the ITS and psbA-trnH regions. Phylogenetic analysis was conducted using the Maximum likelihood method. The result resolved the phylogenetic position of Nigerian species and supported existing subgenera classification into three clades, all with high bootstrap support for the three clades. The result of this study supports the subgenera classification of the genus and further reveals the phylogenetic position of C. longa. Keywords: Curcuma longa, ITS, psbA-trnH, Sanger Sequencing, Zingiberaceae

    It has been shown that the adverse effects of salinity can vary between different varieties of the same plant species. This study was conducted to determine the tolerability of three newly released lines of maize to saline conditions when primed with ethylene diamine tetraacetic acid (EDTA) and salicylic acid (SA) each at 1.0 M concentration; seeds primed with distilled water were used as control. Concentrations of 0, 50, 100, 150 and 300 mM NaCl were tested. The experiment followed a 3x3x5 factorial arrangement of treatments with three replications. The results revealed significant interaction between maize lines and salinity where the germination percentage of line SWAN-LSR-Y was much more affected than the other lines at the salinity level of 50 mM, and its speed of germination was more affected than the others when passing from 150 to 300 mM NaCl. The seedling lengths (radicle and plumule) and seed vigor index were influenced by significant interaction between the primer and salinity, where EDTA enhanced better seedling growth than the other primers when the salinity did not exceed 150 mM. OMR-LSR-SY maize line did not show tolerability at this concentration. Similarly, EDTA and SA treated maize lines showed lower accumulation of reactive oxygen species such as superoxide anion radical (O2-), hydrogen peroxide (H2O2), as well as a decrease in the malondialdehyde (MDA) contents, most importantly in SWAN-LSR-Y and BR9928-OMR-SR-Y maize lines. Catalase (CAT) and superoxide dismutase (SOD) activities were enhanced in SWAN-LSR- Y and BR9928-OMR-SR-Y upon application of EDTA.
  • Molecular Characterization of Potential Crop Pathogens Associated with Weeds as Endophytes in Uniilorin Plantations, Nigeria

    Crop diseases are usually caused by inoculum of pathogens which might exist on alternate hosts or weeds as endophytes. These endophytes, cum pathogens, usually confer some beneficial attributes to these weeds or alternate hosts from protection against herbivores, disease resistance, stress tolerance to secondary metabolites production. This study was therefore carried out to isolate potential crop pathogens which exist as endophytes on weed species in the University of Ilorin plantations. Green asymptomatic leaves were collected from 10 weed species across the plantations, and processed for their endophytic fungi isolation. Isolates were purified into pure cultures and used for molecular identification using the internal transcribed spacer (ITS) region of the ribosomal DNA. Phylogenetic analysis of the fungal sequences using MEGA software revealed 9 fungal genera belonging to 13 species, with species in the genera Curvularia, Epicoccum and Daldinia occurring in more than one weed species, while other genera such as Alternaria, Fusarium, Chaetomium, Macrophomina, Arthrinium and Phomopsis occurred in just one weed species each. Daldinia eschscholtzii was isolated in this study as an endophyte from Loudetia arundinacea for the first time. This plant is very abundant in Nigeria and Africa where it is used majorly for thatching and feeding livestocks. This also represents the first endophytic fungi from the genus Loudetia. Potential relationship between the occurrences of these fungi as endophytes and as pathogens are discussed. These discoveries represent the first large-scale molecular identification and several first reports of endophytes from these weed species. These results also represent the first records of some of these fungi in Nigeria.
  • Effect of planting methods on growth and yield of groundnut cultivars
    A. S. Abdulbaki, B. U. Olayinka, R. T. Mohammed, Hameed Alsamadany, R. B. Murtadha, et al.
    Legume Research, 2021
    Background: The low yield in groundnut which can be partly attributed to poor land preparation methods necessitated the need for alternative strategy of land preparation that will promote higher productivity in groundnut farming. Methods: A field experiment was carried out in two separate locations between May and August in 2016 to assess the effect of planting methods on growth and yield of groundnut cultivars. Result: The results revealed that groundnut crop sown on modified ridges and furrow with narrow furrow planting recorded significantly higher plant height, number of leaves, 50% flowering, yield attributes and yield when compared to other methods of planting All the groundnut cultivars responded positively to all planting methods except those grown on flat surface without beds. However, modified ridges and furrow with narrow furrow planting proved to be the best method.
