Juncus L. (Juncaceae) is a genus of annual and perennial herbs composed approximately 310 species distributed worldwide, but more rarely found in the tropics. Despite an increasing number karyological studies Juncaceae, reports on chromosome numbers Korean taxa have been scarce owing to small size. Here, we present detailed information obtained from 36 individuals 10 taxa. Chromosome eight (J. ...

bilateral finger and palm prints of 500 males and 500 females of the caucasian origin in south iran have been collected and analyzed for both qualitative and quantitative dermatoglyhic features. results show that most of the qualitative features on bilateral and bisexual differences are not significant. however, quantitative features frequently showed significant differences both bilaterally an...

Somatic chromosome numbers were determined for 20 new germplasm accessions of Paspalum, belonging to 17 species collected in Brazil. Chromosome number is reported for the first time for P. reduncum (2n = 18), P. cinerascens (2n = 20), P. cordatum (2n = 20), P. filgueirasii (2n = 24), P. ammodes (2n = 36), P. bicilium (2n = 40), P. heterotrichon (2n = 40), and P. burmanii (2n = 48). New cytotype...

The host response to mycobacterial infection depends on host and pathogen genetic factors. Recent studies in human populations suggest a strain specific genetic control of tuberculosis. To test for mycobacterial-strain specific genetic control of susceptibility to infection under highly controlled experimental conditions, we performed a comparative genetic analysis using the A/J- and C57BL/6J-d...

Abstract Introgression of desirable traits from wild relatives plays an important role in crop improvement, as species have characters such high resistance to pests and pathogens. However, use peanut is challenging because almost all are diploid sexually incompatible with cultivated peanut, which tetraploid (AABB genome type; 2 n = 4x 40). To overcome the ploidy barrier, we used make a same all...

In 2 adult male patients with 49 chromosomes, an XXXXY sex chromosome constitution was confirmed by trypsin-Giemsa banding sites. Clinical findings as well as fingerprint ridge counts were typical of the syndrome. Primary hypogonadism was documented by finding low serum testosterone and raised serum LH and FSH levels. Several radiological abnormalities, not previously described in this syndrome...

Two cell lines, one proficient (Mex+) and one deficient (Mex-) in the ability to remove O6-methylguanine, have been isolated by Epstein-Barr virus-mediated transformation of a single blood sample obtained from a normal human male. Extracts of untreated cells differ in their O6-methylguanine transferase (methyl acceptor protein) activity. Although both lines arise from the same individual, they ...
