Comparative Mapping Between Arabidopsis Thaliana and Brassica Nigra Indicates That Brassica Genomes Have Evolved Through Extensi
Copyright 1998 by the Genetics Society of America Comparative Mapping Between Arabidopsis thaliana and Brassica nigra Indicates That Brassica Genomes Have Evolved Through Extensive Genome Replication Accompanied by Chromosome Fusions and Frequent Rearrangements Ulf Lagercrantz Department of Plant Biology, Swedish University of Agricultural Sciences, S-750 07 Uppsala, Sweden Manuscript received March 27, 1998 Accepted for publication July 24, 1998 ABSTRACT Chromosome organization and evolution in the Brassicaceae family was studied using comparative linkage mapping. A total of 160 mapped Arabidopsis thaliana DNA fragments identi®ed 284 homologous loci covering 751 cM in Brassica nigra. The data support that modern diploid Brassica species are descended from a hexaploid ancestor, and that the A. thaliana genome is similar in structure and complexity to those of each of the hypothetical diploid progenitors of the proposed hexaploid. Thus, the Brassica lineage probably went through a triplication after the divergence of the lineages leading to A. thaliana and B. nigra. These duplications were also accompanied by an exceptionally high rate of chromosomal rearrangements. The average length of conserved segments between A. thaliana and B. nigra was estimated at 8 cM. This estimate corresponds to z90 rearrangements since the divergence of the two species. The estimated rate of chromosomal rearrangements is higher than any previously reported data based on comparative mapping. Despite the large number of rearrangements, ®ne-scale comparative mapping between model plant A. thal- iana and Brassica crops is likely to result in the identi®cation of a large number of genes that affect important traits in Brassica crops. NE important aspect of genome evolution is polyploid (Masterson 1994). -

Box 524, Auckland Park 2006, Johannesburg, South Africa Received 4 November 2011; received in revised form 18 November 2011; accepted 21 November 2011 Abstract Asphodelus fistulosus or onionweed is recorded in South Africa for the first time and is the first record of an invasive member of the Asphodelaceae in the country. Only two populations of this plant have been observed, both along disturbed roadsides on the West Coast of South Africa. The extent and invasive potential of this infestation in the country is still limited but the species is known to be an aggressive invader in other parts of the world. © 2011 SAAB.

Effect of Feeding Brassica Juncea Seeds on Experimentally Induced Hyperlipidemia
EMAD-UD-DIN ET AL (2014), FUUAST J. BIOL., 4(1): 61-64 EFFECT OF FEEDING BRASSICA JUNCEA SEEDS ON EXPERIMENTALLY INDUCED HYPERLIPIDEMIA MUHAMMAD EMAD-UD-DIN, GHAZALA YASMEEN, NAZISH IQBAL KHAN AND LUBNA NAZ Pathophysiology Unit, Department of Physiology, University of Karachi, Karachi, Pakistan. Corresponding Authors e-mail: [email protected] Abstract Cardiovascular Disease (CVD) is major cause of death worldwide. Atherosclerosis is principal underlying mechanism, stimulated by hyperlipidemia. Substantial evidences suggest that atherosclerosis can be prevented or at least retarded by controlling serum lipids, especially cholesterol, at initial stages. The study was aimed to investigate the antihyperlipidemic potential of Brassica juncea seeds in cholesterol-fed rabbits owing to expected lipid lowering effect of B. juncea seeds. Age matched 18 rabbits were randomly divided into three equal groups control, hyperlipidemic and treated. Following one week acclimatization, control group kept on normal animal chow, 5% atherogenic diet was administered to hyperlipidemic group while treated were fed 10% dried Brassica juncea seeds along with atherogenic diet for eight weeks. Blood specimens were obtained and assayed for lipid profile (TC, HDL-C, LDL-C, TG, vLDL, TC/HDL-C). Data was analyzed using t-test at 0.05. High cholesterol diet significantly increased plasma TC (p<0.01, 60.25%), LDL-C (p<0.05, 10.8%), TG (p<0.05, 19.9%) while rise in HDL-C (23.1%) and vLDL (18.4%) remained non-significant as compared with control. Brassica juncea seeds consumption showed significant lipid lowering activity TC (p<0.05, -24.7%), HDL-C (p<0.05, 36.7%), LDL-C (p<0.05, -34%), TG (p<0.01, -41%) and vLDL (p<0.05, -40.7%) in comparison to hyperlipidemic counterparts. -

NHESP is responsible for the conservation and protection of hundreds of species that are not hunted, fished, trapped, or commercially harvested in the state. The Program's highest priority is protecting the 176 species of vertebrate and invertebrate animals and 259 species of native plants that are officially listed as Endangered, Threatened or of Special Concern in Massachusetts. Endangered species conservation in Massachusetts depends on you! A major source of funding for the protection of rare and endangered species comes from voluntary donations on state income tax forms.
