Cell membrane integrity, callose accumulation, and root growth in aluminum-stressed sorghum seedlings
Emily Jepkosgei Too; Beatrice Ang’iyo Were; Onkware, Augustino; Anders S. Carlsson; Mulatu Geleta; Gudu, Samuel; T. Bryngelsson (2015-08-21)Aluminum stress usually reduces plant root growth due to the accumulation of Al in specific zones of the root apex. The objectives of this study were to determine the localization of Al in the root apex of Sorghum bicolor ... -

Combining ability of some sorghum lines for dry lands and sub-humid environments of East Africa
Rathore Abhishek; Beatrice Ang’iyo Were; Mary Mgonja; Deshpande Santosh; Mneney Emmarold; Onkware, Augustino; Gudu, Samuel; Ringo Justin (2015-08-19)Sorghum (Sorghum bicolor L. Moench) is a major food crop grown in dry lands and sub-humid areas of East Africa. A study was conducted between 2010 to 2012 in dry lands (Miwaleni, Kiboko) and sub- humid (Ukiriguru) ... -
Genetic Diversity in Cultivated Sesame (Sesamum indicum L.) and Related Wild Species in East Africa
Gudu, Samuel; Otto George Dangasuk; Beatrice Ang’iyo Were; Benson Ouma Nyongesa; Onkware, Augustino (2015-08-21)Genetic diversity of traditional sesame landraces and related wild species in East Africa remains largely unexplored. Knowing what fraction of the available genetic diversity is actually used by the farmers is of central ... -
Genetic relationship between sesame (Sesamum indicum L.) and related wild species based on chromosome counts and isozyme markers
Onkware, Augustino; Beatrice Ang’iyo Were; Gudu, Samuel; Benson Ouma Nyongesa; Otto George Dangasuk (2015-08-19)Sesame is an orphan crop with little research attention in Kenya. Genetic relationship between cultivated sesame and related wild species in Kenya is not well known. The objective of this study was to determine genetic ... -
Physiological characterization of kenyan sorghum lines for tolerance to aluminium
Matonyei, Thomas; Cheprot, Reuben K.; Maritim K. K.; Beatrice Ang’iyo Were; Dangasuk O. George; Onkware, Augustino; Gudu, Samuel (2015-08-21)Eighty nine Kenyan sorghum lines were screened for tolerance to aluminium toxicity in nutrient solution. Relative net root growth; root tip aluminium content and variation in organic acid exudation were used to determine ... -
Response of selected sorghum (Sorghum bicolor L. Moench) germplasm to aluminium stress
Evans, Ouma; Emily Jepkosgei Too; Beatrice Ang’iyo Were; Onkware, Augustino; Justin Hanson Ringo; Kisinyo, Peter; Anders S. Carlsson; Mulatu Geleta; Mulatu Geleta (2015-08-19)Sorghum (Sorghum bicolor L. (Moench) is an important food security crop in sub-Saharan Africa. Its production on acid soils is constrained by aluminium (Al) stress, which primarily interferes with root growth. Sorghum ...
