1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

15 صفحه اولGenetical and Biochemical Studies of Histidine-requiring Mutants of Neurospora Crassa. Iv. Linkage Relationships of Hist-3 Mutants.
istidine-3 (hist-3) mutants of Neurospora crassa were chosen for detailed TFEhhemical studies, complementation mapping, and intercrosses because they were shown to exhibit deficiencies in one or the other or both of two distinguishable, though apparently closely related types of biochemical functions. Preliminary heterokaryon complementation studies ( WEBBER 1959, 1960; CATCHESIDE 1960) showed ...
متن کاملGenetical and Biochemical Studies of Histidine-Requiring Mutants of Neurospora Crassa. II. Evidence concerning Heterogeneity among Hist-3 Mutants.
HE hist-3 mutants of Neurospora crassa were chosen for extensive genetic analysis because of the finding by HAAS, MITCHELL, AMES and MITCHELL (1952) that two hist-3 mutants, TI 710 and C140, though genetically allelic, appeared to be physiologically dissimilar. T1710 was shown to accumulate during growth a single imidazole, L-histidinol (AMES, MITCHELL and MITCHELL 1953), while C140 accumulates...
متن کاملPhysiological studies of salmonella histidine operator-promoter mutants.
S. typhimurium hisO mutations are cis dominant and trans recessive and occur in a regulatory segment separate from but adjacent to the first structural gene of the histidine operon, hisG. Strains containing hisO mutations singly and in combination with other regulatory mutations were examined for their content of L-histidinol phosphate phosphatase when grown on limiting and on excess L-histidin...
