Abstmct-Protein variation among 37 species of carcharhiniform sharks was examined at 17 presumed loci. Evohttionary trees were inferred from these data using both cladistic character and a distance Wagner analysis. Initial cladistic character analysis resulted in more than 30 000 equally parsimonious tree arrangements. Randomization tests designed to evaluate the phylogenetic information conten...

Brown flatsedge (Cyperus fuscus) is widely distributed in Europe, Asia, the Indian subcontinent, and the Mediterranean region of Northern Africa. It was apparently introduced into North America in the late 1800s and has steadily moved southward and westward. Brown flatsedge is reported new to Arkansas and Mississippi herewith. Field observations from early spring until frost were made between 2...

Two new double-headed protease inhibitors have been isolated from black-eyed peas. The isoinhibitors can be purified to homogeneity with greater than 90% recovery in a four-step procedure by means of sequential affinity chromatography on trypsin-Sepharose and chymotrypsin-Sepharose affinity columns. The isoinhibitors both have molecular weights near 8,000 and both have the same NH1-terminal res...

A lectin has been isolated from the roots of 5-day soybean (Glycine max (L) cultivar Chippewa) seedlings, and its properties have been compared to those of the soybean seed lectin. The sugar-binding activities of the two lectins, both in terms of specific hemagglutinating activity and sugar specificity, are indistinguishable. Molecular properties of the two lectins, measured as relative molecul...

The desert Southwest is the oldest area of continuous crop production in continental USA. Tepary beans (Phaseolus acutifolius A. Gray) were a part ancient, irrigated cropping systems, but they nearly lost during twentieth century. They are now subject heightened research and breeding activity. We wished to ascertain field performance varieties improved by selection within region with those sele...

A factorial experiment with two factors was carried out at the Seed Technology Lab., College of Agriculture, University Baghdad in 2018 order to study effect seed priming gibberellic acid (GA3) (0, 100, 300 and 500 mgL-1) on germination seedling growth deteriorated oat cultivars (Shifaa, Shofan11). The complete randomized design used four replications. results showed that cultivars, soaking dif...
