    Black mischief: crime, protest and resistance in colonial Kenya (1993)

    Topics: History
    Notes: This article examines the history of African resistance to colonial rule among the Nandi and Kipsigis peoples of Kenya's Western Highlands. Anti-colonial protest centred on the activities of a group of ritual leaders, the orkoiik of the Talai clan, who were believed to possess supernatural powers of prophecy and divination. Between the late 1890s and 1905, the orkoiyot Koitalel had come to prominence as a leader of resistance to conquest. After his defeat the British briefly attempted to harness his Talai clansmen to the system of colonial government, promoting them as chiefs. This move was based upon a misunderstanding of the status of the orkoiik, whose powers often stood in direct conflict with the authorityof the elders and who were greatly feared by many Nandi and Kipsigis. By the igsos the orkoiik were deeply implicated in much criminal activity, especially the theft of livestock from European settler farmers. On three occasions orkoiik attempted to organize armed risings.The article concludes with a discussion of the place of the orkoiik in the historiography of Kenya. Although Koitalel and Barserion are commonly presented as heroes of a glorious resistance to colonialism, it is suggested that this interpretation fails to reflect the deep ambiguity of the status of the orkoiik, and the complexity of the struggles that took placewithin African societies under colonial rule.

    Notes: Conclusion The World Data Center-A for Paleoclimatology, located in the NOAA/NGDC Paleoclimatology Program, is committed to providing the scientific community with easy access to all paleoenvironmental data. Efforts to make archived data readily available include international coordination of data acquisition, management, and distribution, sponsoring workshops and data cooperatives to facilitate the compilation of important data sets, development of a browse and visualization software package (PaleoVu), and dispersal of archived data on magnetic media or over ANONYMOUS FTP/INTERNET. The program publishes a semi-annual newsletter that highlights latest developments and accomplishments in the area of paleoenvironmental data for global change research. Contributions to the newsletter are welcome from researchers describing their efforts to coordinate the free flow of paleoclimate data throughout the international scientific community.

    Organization, inheritance and expression of acetohydroxyacid synthase genes in the cotton allotetraploid Gossypium hirsutum (1995)

    Notes: Abstract The acetohydroxyacid synthase (AHAS) gene family of the cotton AD allotetraploid Gossypium hirsutum has been cloned and characterized. We have identified six different AHAS genes from an analysis of genomic clones and Southern blots of genomic DNA. Four of the six genes are organized as tandem pairs, in which the genes are separated by only 2–3 kb. Conservation of restriction fragment length polymorphisms between G. hirsutum and A-genome and D-genome-containing diploid cottons was sufficient to assign the single genes in clones A5 and A19 to the A and D subgenomes, respectively. Each diploid genome has one tandem pair, but in these cases we could not make specific subgenomic assignments. DNA and deduced amino acid sequences were determined for the A5 and A19 genes, and an AHAS cDNA clone isolated from a leaflibrary. The sequence of the A19 gene matches that of the cDNA clone, while the A5 gene is 97.8% similar. The four genes comprising the tandem pairs are much less similar to the cDNA clone. The deduced amino acid sequences of the mature polypeptides encoded by the A5 and A19 genes are collinear with the housekeeping forms of AHAS from Arabidopsis thaliana, Nicotiana tabacum and Brassica napus. The constitutive expression of A5 and A19 was confirmed with RNase protection assays and northern blots. We conclude that these genes encode the main house-keeping froms of AHAS in G. hirsutum. Among the four AHAS genes comprising the two tandem pairs, at least two are functional. These genes exhibit either low-level constitutive expression (one or both of the ‘downstream’ genes of each pair), or highly specific expression in reproductive tissue (one or both of the ‘upstream’ genes of each pair). The AHAS gene family of G. hirsutum is more complex than that of other plants so far examined.

    Characterization and expression of Metallothionein-like genes in cotton (1996)

    Notes: Abstract We have characterized cotton (Gossypium hirsutum L.) genes encoding type 1 metallothionein-like proteins that are highly expressed in roots. Little or no expression of these genes was detected in other organs and tissues. The deduced amino acid sequences have a high degree of similarity with type 1 metallothionein-like proteins from other plants, including a central hydrophobic domain flanked by conserved cysteine-rich motifs. The type 1 metallothionein-like genes of cotton are encoded by a small gene family. One gene (MT1-A) was analyzed in detail and found to have three exons which are 52, 83 and 397 bp long, and two introns 130 and 1042 bp in length. Three of the type 1 metallothionein-like genes are organized in a tandom array, and the 5′-flanking regions of these genes share a high degree of sequence similarity. Two of the clustered genes (MT1-A andMT1-B) are expressed at about equal levels in roots and use the same transcription start site. A 640 bp promoter fragment from theMT1-A gene was sufficient to direct expression of beta-glucuronidase (GUS) in transformed cotton roots. The expression was highest near the root tip.

    Characterization and expression of chitinase and 1,3-β-glucanase genes in cotton (1996)

    Notes: Abstract We have isolated cDNA clones representing mRNAs encoding chitinase and 1,3-β-glucanase in cotton (Gossypium hirsutum L.) leaves. The chitinase clones were sequenced and found to encode a 28,806 Da protein with 71% amino acid sequence similarity to the SK2 chitinase from potato (Solanum tuberosum). The 1,3-β-glucanase clones encoded a 37,645 Da protein with 57.6% identity to a 1,3-β-glucanase from soybean (Glycine max). Northern blot analyses showed that chitinase mRNA is induced in plants treated with ethaphon or salicylic acid, whereas the levels of 1,3-β-glucanase mRNA are relatively unaffected. Southern blots of cotton genomic DNA and genomic clones indicated chitinase is encoded by a small gene family of which two members, Chi 2;1 and Chi 2;2, were characterized. These genes share 97% sequence identity in their transcribed regions. The genes were found to have three exons which are 309, 154 and 550 bp long, and two introns 99 and 154 bp in length. The 5′-flanking regions of Chi 2;1 and Chi 2;2 exhibit a large degree of similarity and may contain sequences important for gene response to chemical agents and fungal attack.
