Cytology and Genetics of a Tissue Culture-Derived Soybean Genic Male-Sterile, Female-Sterile
Get PDFA completely male-sterile, female-sterile mutant was derived from tissue culture of cv. Calland. The primary goal was to identify its inheritance, allelism, and cytology. Calland sterile (TC) was nonallelic with st2, st3, st4, and st5 female-sterile and malesterile mutants. In all crosses, except st5, single-gene recessive inheritance was documented. Critical ratios, 15 fertile: 1 sterile (for two loci) and 45 fertile: 19 sterile (for three loci), were observed in the F2 families from the cross of heterozygous Calland TC andSt5st5. F3 segregation data confirmed the duplicate factor inheritance of Calland TC. Calland TC was designated St6st6st7st7 and assigned the genetic type collection number T331H. The mutant was studied for abnormalities during microsporogenesis. The first abnormality was the occurrence of hollow-core nucleoli in sporogenous mass cells. During anaphase I and anaphase II of meiosis, lagging chromosomes and unequal chromosome segregation were observed, resulting in numerically and genetically unbalanced microspore nuclei. This also resulted in four microspores, and in five to eight microspores held together by common callose walls. Dissolution of callose released microspores into locules. Most microspores enlarged and were surrounded by microspore/pollen walls. After microspore mitosis, most young pollen grains degenerated. No viable pollen grains were evident. The sterility in Calland TC can be attributed to desynapsis.This article is from Journal of Heredity 88 (1997): 129.</p

The new South African Parliament : an evaluation of parliament's oversight function of the executive
No full textBibliography: leaves 66-68.The aim of this study is to evaluate how the new and democratically elected South African Parliament as an institution has been able to hold the executive accountable for their activities. Accountability of the rulers has been identified as a central element In democratic government. In representative democracies there are two major models of government: presidential and parliamentary government. These two models have different methods for dealing with the issue of legislative oversight. Literature shows that this function is more effective in presidential systems than in parliamentary systems, since the presidential model provides a stronger constitutional framework for legislative oversight. The model that can be used to analyse South Africa is closely linked to the parliamentary model. However, the role of the President, the sovereign Constitution, and the anti-defection clause makes South Africa more of a hybrid-parliamentary model. As South Africa can be linked to the parliamentary model, this implies that Parliament will not be able to hold the executive effectively accountable. There are other non-constitutional factors that have an impact on Parliament's oversight function. In South Africa, the non-constitutional factors that have been in place in these five first years of democracy enhance the consequences of the parliamentary model. This means that these factors add to the existing provisions for ineffective accountability of the executive by Parliament. These are the large majority of the ANC, the strict internal discipline of the ANC, the weak opposition in Parliament, the lack of resources and staff in Parliament, and the lack of capacity, experience and expertise by the MP's. As the example of Sarafina 2 shows, these factors, and especially the large majority of the ANC in Parliament, add to the inability of the new South African Parliament to effectively hold the executive accountable
