Genetic Improvement of African Maize towards Drought Tolerance: A Review
(IISTE, 2016)
Africa supports a population of over 1 billion people with over half of them depending on maize for food and
feed either directly or indirectly. Maize in Africa is affected by many stresses, both biotic and abiotic ...
Mutation EthAW21R confers co-resistance to prothionamide and ethionamide in both Mycobacterium bovis BCG and Mycobacterium tuberculosis H37Rv
(Dove Press, 2018-06)
Ethionamide (ETA) and prothionamide (PRO) are interchangeably used in tuberculosis
(TB) chemotherapy regimens. Subtle discrepancies between biochemical and genetic
information on the modes of sensitivity and resistance ...
Coevolutionary fine-tuning: evidence for genetic tracking between a specialist wasp parasitoid and its aphid host in a dual metapopulation interaction
(Cambridge University Press, 2012-04)
In the interaction between two ecologically-associated species, the population structure of one species may affect the population structure of the other. Here, we examine the population structures of the aphid Metopeurum ...
The 'Cake on the plate' syndrome ... and how specialist tansy aphids avoid extinction by hungry predators and parasitoids: insights from the use of polymorphic microsatellite markers
(2008)
It was initially shown from 12.2 m high suction trap aerial density data and later confirmed using polymorphic molecular markers (initially allozymes, later high resolution DNA markers, especially microsatellites), that ...
A survey of root knot nematodes and resistance to Meloidogyne incognita in sweet potato varieties from Kenyan fields
(Elsevier, 2016-11)
The root knot nematode, Meloidogyne is one of the most economically damaging plant parasitic nematode
groups, and are widely distributed in Kenyan agro-ecosystems. The aim of this study was to
determine the diversity of ...
Seagrass Removal Leads to Rapid Changes in Fauna and Loss of Carbon
(Frontiers, 2019-03)
Seagrass habitats are important natural carbon sinks, with an average of ∼14 kg C
m−2 buried in their sediments. The fate of this carbon following seagrass removal
or damage has major environmental implications but is ...
Seagrass Loss and Sub-Surface Carbon Fate: Insights from a Long-Term Experimental Removal in Gazi Bay, Kenya
(Jupiter Publishers, 2021-08)
Seagrass meadows are considered as global hotspots of blue carbon stocks. However, they suffer global cover loss mainly due to anthropogenic
activities. Few is known on the impact of seagrass loss on their blue carbon ...
Detection and Profiling of AntibioticResistance among Culturable Bacterial Isolates in Vended Food and Soil Samples
(Hindawi, 2020-08)
+e emergence and persistence of antibiotic resistance remain formidable health challenges. +is study aimed at detecting and
profiling antibiotic resistance of bacterial contaminants in vended food and the environment. ...

Variation in Seagrass Carbon Stocks Between Tropical Estuarine and Marine Mangrove-Fringed Creeks
(Frontiers in Marine Science, 2020-08)
Seagrass and associated blue carbon ecosystems are important carbon sinks, and hence understanding their spatial and temporal variability is vital in appreciating their potential roles in climate change mitigation and ...
