    • Tracking the Expression of Photosensitive Genic Male Sterility Gene in Rice 

      Njiruh, Nthakanio P.; Xue, Qingzhong (2013-09)
      Photoperiod sensitive genic male sterile rice lines contain genes that induce complete male sterility in high temperature and long day light length period, but are male fertile under low temperature ...

    • Tracking the expression of photosensitive genic male sterility genes in rice 

      Njiruh, Nthakanio P.; Qingzhong, Xue (Academic Journals, 2013-11)
      Photoperiod sensitive genic male sterile rice lines contain genes that induce complete sterility in high temperature and long day light length period, and revert to fertility in optimum low temperature and short day light ...

    • Trait matching of flower visitors and crops predicts fruit set better than trait diversity 

      Garibaldi, Lucas A.; Otieno, Mark; Bartomeus, Ignasi; Bommarco, Riccardo; Klein, Alexandra M.; Cunningham, Saul A.; Aizen, Marcelo A.; Boreux, Virginie; Garratt, Michael P. D.; Carvalheiro, Luısa G.; Kremen, Claire; Morales, Carolina L.; Schuepp, Christof (Wiley Online Library, 2015)
      Summary Understanding the relationships between trait diversity, species diversity and ecosystem functioning is essential for sustainable management. For functions comprising two trophic levels, trait matching between ...

    • The Utility of Aerial Pan-Trapping for Assessing Insect Pollinators Across Vertical Strata 

      Nuttman, Clive; Otieno, Mark; Kwapong, Peter K.; Combey, Rofela; Willmer, Pat; Potts, Simon G. (2011)
      Insect pollinators provide a critical ecosystem service by pollinating many wild flowers and crops. It is therefore essential to be able to effectively survey and monitor pollinator communities across a range of habitats, ...

    • Utilization of proteins and nucleic acids in the study of gene function: a comparative review 

      Mwololo, J.K.; Karaya, H.G.; Munyua, J.K.; Muturi, Phyllis W.; Munyiri, S.W. (2010)
      Proteomics is one of the fastest growing areas in areas of research, largely because the global-scale analysis of proteins is expected to yield more direct understanding of function and regulation than analysis of genes. ...

    • Witchweed’s Suicidal Germination: Can Slenderleaf Help? 

      Mwakha, Fridah A.; Budambula, Nancy; Neondo, Johnstone O.; Gichimu, Bernard M.; Odari, Eddy O.; Kamau, Peter K.; Odero, Calvins; Kibet, Willy; Runo, Steven (MDPI, 2020-06)
      The parasitic plant Striga hermonthica (Delile) Benth. is stimulated to germinate by biomolecules (strigolactones) produced in the roots of host and some non-host plants. Non-hosts induce Striga’s suicidal germination ...

    • Yield of three Commercial Watermelon Cultivars in Kenya as compared to a local landrace 

      Gichimu, Bernard M.; Owuor, B.O; Dida, M. M. (2010)
      High yield is a major goal for watermelon (Citrullus lanatus) breeders. The objective of this study was to measure the yield potential of some watermelon accessions available in Kenya and identify high yielding ones for ...

    • Yield Selection within Coffea arabica cv. Ruiru 11 

      Gichimu, Bernard M.; Nyende, A.B.; Gichuru, E. K.; Mamati, George E. (SCIENCEDOMAIN international, 2012-08-17)
      Aims: This study was aimed at identifying high yielding Ruiru 11 sibs in varying growing conditions. The study also intended to measure the extent to which cherry yields of Ruiru 11 are affected by the environment. Study ...
