Three minimum tile paths from bacterial artificial chromosome libraries of the soybean (Glycine max cv. 'Forrest'): tools for structural and functional genomics

Background  

The creation of minimally redundant tile paths (hereafter MTP) from contiguous sets of overlapping clones (hereafter contigs) in physical maps is a critical step for structural and functional genomics. Build 4 of the physical map of soybean (Glycine max L. Merr. cv. 'Forrest') showed the 1 Gbp haploid genome was composed of 0.7 Gbp diploid, 0.1 Gbp tetraploid and 0.2 Gbp octoploid regions. Therefore, the size of the unique genome was about 0.8 Gbp. The aim here was to create MTP sub-libraries from the soybean cv. Forrest physical map builds 2 to 4.     

Integrated management of <Emphasis Type="Italic">Helicoverpa armigera</Emphasis> in chickpea in rainfed areas of Punjab,Pakistan

The pod borer Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) is an important insect pest of chickpea and several other crops in Asia, Africa and Australia. The present studies were carried out on integration of various practices for the management of H. armigera in Punjab, Pakistan, during 2004-05. Chickpea variety ‘CM-2000’ was selected for evaluating various strategies such as cultural, mechanical, biological, microbial, and chemical control, individually and in various possible combinations, for the management of H. armigera at three different locations. Integration of weeding, hand picking and indoxacarb (an oxadiazine insecticide) proved to be the most effective in reducing the larval population and pod infestation and resulted in the maximum grain yield. The larval population of the combined effect of these practices was not significantly different from hand picking + indoxacarb, weeding + indoxacarb, and indoxacarb alone. Hand picking in combination with Bacillus thuringiensis, and weeding + hand picking, also controlled the larval population significantly, but was inferior to the above treatments. The release of Trichogramma chilonis Ishii (Hymenoptera: Trichogrammatidae) did not control H. armigera. It was concluded on the basis of the cost — benefit ratio that hand picking was the most cost-effective method for the control of H. armigera, while the maximum increase in grain yield was obtained in plots with weeding, hand picking, and indoxacarb.

UPTAKE AND DISTRIBUTION OF SELENIUM,NITROGEN AND SULFUR IN THREE BARLEY CULTIVARS SUBJECTED TO SELENIUM APPLICATIONS

Selenium (Se) is an essential micronutrient for humans and animals, and also affects plant metabolism. In this study, the effects of increasing doses of Se application on the uptake of selenium (Se), nitrogen (N), and sulfur (S) content of three barley cultivars were investigated. The analysis indicated that the Se contents were highest in root tissues, intermediate in grain, and lowest in stem tissues in all cultivars. Total Se accumulations (whole plant) were highest in ‘Bülbül 89’ (0.171 mg kg^?1), intermediate in ‘Çetin 2000’ (0.153 mg kg^?1), and lowest in ‘Tarm 92’ cultivars (0.124 mg kg^?1). In all cultivars, the increase in grain Se content resulted in a decrease in the grain N content. While ‘Bülbül 89’ can be suggested for biofortification purposes, less Se accumulating ‘Tarm 92’ cultivar can be suggested as a fodder in Se contaminated or high Se containing areas.
