Cytoplasmic male sterility (CMS) is a maternally inherited trait in which plants do not produce functional pollen during anther development; it plays a key role in hybrid seed production. CMS in kenaf (Hibiscus cannabinus L.) was first found by our group, but little is known about its molecular mechanism. To reveal the possible mechanism, a comparative(More)
This review provides a description of the biochemistry and enzymology of the alpha-aminoadipate pathway for lysine biosynthesis in fungi. The alpha-aminoadipate pathway is unique to fungi and is thus a potential target for the rational design of antifungal drugs. The present state of knowledge of the mechanisms of the seven enzymes in the pathway is(More)
There are five distinct core structures in the lipopolysaccharides of Escherichia coli and at least two in Salmonella isolates, which vary principally in the outer core oligosaccharide. Six outer core glycosyltransferases, E. coli K-12 WaaG, WaaB, and WaaO and Salmonella typhimurium WaaI, WaaJ, and WaaK, were cloned, overexpressed, and purified. A novel(More)
Homocitrate synthase (acetyl-coenzyme A: 2-ketoglutarate C-transferase; E.C. 2.3.3.14) (HCS) catalyzes the condensation of acetyl-CoA (AcCoA) and alpha-ketoglutarate (alpha-KG) to give homocitrate and CoA. Although the structure of an HCS has not been solved, the structure of isopropylmalate synthase (IPMS), a homologue, has been solved (Koon, N., Squire,(More)
In this thesis, mixed primitive variable based finite element formulations are developed to solve linear and nonlinear fluid-structure interaction problems involving incompressible (or almost incompressible) fluid models. The mixed elements are used according to the inf-sup condition. It is pointed out that along the fluid-structure interfaces, different(More)
Homocitrate synthase (acetyl-coenzyme A:2-ketoglutarate C-transferase; E.C. 2.3.3.14) catalyzes the condensation of AcCoA and alpha-ketoglutarate to give homocitrate and CoA. The enzyme was found to be a Zn-containing metalloenzyme using inductively coupled plasma mass spectrometry. Dead-end analogues of alpha-ketoglutarate were used to obtain information(More)
A cytoplasmic male sterile line (designated as M2BS) was obtained from an indica rice maintainer M2B induced by partial-length HcPDIL5-2a (Hibiscus cannabinus protein disulfide isomerase-like) transformation. The anther of M2BS was short, slender, hygrophanous, and fissured. I2-KI staining method showed that there was typical and spherical abortion in(More)
