The rising incidence of cancer is a major concern globally being leading cause early mortality in most countries. This burden projected to increase 28.4 million cases worldwide by 2040 and yet, may be worsened continuous exposure risk factors due sheer shift from consumption natural nutrients. To reverse this trend, it imperative source novel anticancer metabolites plants that could minimize carcinogenic effects suppressing the proliferation survival cells. study aimed at characterizing...
This article explores the pivotal role of herbaria in supporting taxonomic research Nigeria and highlights need to improve herbarium infrastructure enhance plant diversity country. Thirteen are currently recognized on Index Herbariorum database collectively house about 260,000 specimens. The Forest Herbarium Ibadan (FHI) is largest, containing nearly 50% these Based occurrence data Nigerian plants Global Biodiversity Information Facility (GBIF), herbaria, namely FHI, ABUH, LUH, NAUH, UNICAL,...
The effects of infestation by the bird cherry-oat aphid (BCA), (Rhopalosiphum padi L) and Russian wheat (RWA) (Diuraphis noxia Mordvilko) on callose deposition transcription genes related to accumulation were investigated in barley (Hordeum vulgare L. cv. Clipper). BCA, which gives no visible symptoms, induced very limited deposition, even after 14 days infestation. In contrast, RWA, causes chlorosis, white yellow streaking leaf rolling, already 24 h longitudinal veins. was pronounced 72 h,...
Foliar epidermal characters of ten species from the genus Cassia L. Emend. Gaertner, Senna Miller and Chamaecrista Moench found in South Western Nigeria were studied. The aim was to establish some useful diagnostic features that may be employed combination with other as intra or inter-specific generic tools for their delimitation. Our results revealed exciting are helpful identification each species. These include guard cell area, stomatal index frequency, presence absence trichomes, types...
The Russian wheat aphid (RWA, ( Diuraphis noxia ) and the Bird cherry‐oat (BCA, Rhopalosiphum padi L.) cause severe damage to grain crops, including barley. An investigation of effects these aphids on a susceptible cultivar revealed that BCA‐infested barley plants remained healthy looking for 2 weeks after feeding commenced. In contrast, signs stress damage, chlorosis leaf necrosis were evident in RWA‐infested plants. Our study suggests vascular tissue because sustained by BCA was not as...
Investigation of comparative effects feeding damage by the Russian wheat aphid (RWA, biotype SA1, Diuraphis noxia Mordvilko) on leaf blades susceptible and resistant cultivars (Triticum aestivum L. var Betta Betta-Dn1 respectively) were carried out to establish level ultrastructural caused this possible limitation induced which could be ascribed resistance gene Dn1 over cultivar. Ultrastructurally, sustained less vascular tissue as well mesophyll during experimental period. Both inter-...
Studies on the leaf epidermal characters and petiole anatomy of four species Citrus L. viz., C. limon (L.) Burm., paradisi Macf., reticulata Blanco sinensis Osbeck were carried out to establish document their foliar anatomical with aim separating them from modified varieties been cultivated globally. Leaf features that revealed close relationship among these taxa include hypostomatic condition, stomata shape type, presence secretory cavity adaxial surface, polygonal cells. The absence...
Psychosis is a mental disorder characterised by multiple symptoms affecting thought, emotion, perception, volition and general wellbeing of the sufferers. Psychotic patients in Nigeria are mostly managed traditional medical practitioners, who employ varieties medicinal plants. This review was conducted to compile list antipsychotic plants also probe into active metabolites that have been scientifically implicated for management psychosis its opportunistic diseases. The information used...
Macromorphological characters of some species Cassia L. emend. Gaertner, Senna Miller and Chamaecrista Moench occurring in South Western Nigeria were studied. The aim was to search for stable, distinctive diagnostic the identification these genera their species. Qualitative noted recorded while quantitative observations done by use a metric ruler measurements taken nearest centimeters. habit ranges from all shrubs Senna, herbs studied are trees. shape leaflet apex varies both species, it is...
Leaf anatomical characters of twelve species from the genus Cyperus , a known to contain with both C 3 and 4 plants, have been investigated. We investigated established usefulness all‐inclusive functional leaf for identifying photosynthetic pathways these species. The were C. articulatus L., compressus difformis dilatatus Schum. & Thonn., distans esculentus haspan imbricatus Retz., iria rotundus sphacelatus Rottb. tenuiculmis (Boeck.) Hooper, collected locations in southwestern Nigeria....

The C_3 and C_4 photosynthetic pathways in dicotyledons were investigated with the four species of Boerhavia occurring Nigeria using light microscopy. study is not yet well reported on as done for monocotyledons. features cross-examined stomata index, size, inter-stomatal distance, stomatal density, interveinal intercellular air spaces, leaf thickness, mesophyll Kranz tissue, one cell distant count criterion, maximum lateral vein density distance. Based these features, (B. erecta, B....
Inflorescence and floral morphological characters in twelve species of Cyperus – a genus known to have C3 C4 photosynthetic were investigated order check their usefulness delimiting into groups. Plant collected from different locations within Southwestern Nigeria. Qualitative noted recorded while some quantitative measured with metric ruler the nearest centimeter others counted. The results revealed that compound umbellate inflorescence, digitately arranged spikelets short not over 1cm long...
The responses of seven selected plant species to gemstone mining activities were investigated based on data obtained from exo- and endo- morphology the leaves with aim establishing pollution underlining mechanism which could possibly explain such responses. Both qualitative quantitative methods, using visual microscopic assessment adopted. Results foliar showed that most had significant increase (p<0.05) in leaf area petiole length polluted sites compared those unpolluted site though...
