We have constructed a phylogenic tree for land plants by comparing the 5S rRNA sequences. The tree suggests that the Bryophyta and the Pteridophyta separated from each other after the emergence of the Spermatophyta. In the Pteridophyta, Psilotum (whisk fern) firstly separated, and a little after Lycopodium (clubmoss) separated from the ancestor common to Equisetum (horsetail) and Dryopteris (fern). During the Spermatophyta evolution, the gymnosperms (Cycas and Ginkgo have been studied here) and the angiosperms (flowering plants) separated, followed by the separation of Cycas (cycad) and Ginkgo (maidenhair tree) on one branch, and various flowering plants on the other. Nitella (stonewort) separated at about the same time of the Spermatophyta and the Pteridophyta/Bryophyta separation.

Chromosomal Study on the Three Local Races of the Striated Spined Loach

Cobitis taenia striata

Three local races of the striated spined loach (Cobitis taenia striata) are studied karyologically. The large race is tetraploid, while the middle and small races are diploid. Aneuploidy is found among males of the small race. Speciation at the diploid level is supposed to occur besides that by polyploidy. Morphological differentiation of the sex chromosome is also discussed.

γ-Glutamyltranspeptidase in Urine of Ascites Hepatoma Rat Detected on Isoelectric Focusing in Agarose Gel

γ-GTP excreted in urine of hepatocarcinoma rat was investigated by use of isoelectric focusing in agarose gel. Some of the tumor specific isoenzymes recognized at low pI, 4.5-5.0, indicated an affinity on Con A-Sepharose column. No remarkable Con A-boundable isoenzymes were observed at this pI region in normal rat urine.
