Improvement of a useful enzyme (subtilisin BPN′) by an experimental evolution system
In order to improve a natural enzyme so as to fit industrial purposes, we have applied experimental evolution techniques comprised of successive in vitro random mutagenesis and efficient screening systems. Sub...

Differing kinase activity of the c-yes and c-src gene proteins in TPA-induced megakaryocytic differentiation of T-33 and K562 cell lines
We examined the protein kinase (PK) activity of the c-yes and c-src gene proteins (c-YES, c-SRC) at an early phase of 12-O-tetradecanoyl phorbol-13-acetate (TPA)-induced megakaryocytic differentiation of T-33 ...

Element analysis and radioactivity measurement within a wood disk by neutron activation analysis
We have analyzed 16 elements and the radioactivity of 210Pb in a wood disk, across the annual rings to find out a promising tool for dendrochronology (chronology of wood) both for a Japanese wood, Cryptomeria jap...

Effects of evening and nighttime leaf wetting on stomatal behavior of Cryptomeria japonica growing in dry soil
To examine the hypothesis that stomatal behavior of plants in dry soil is influenced by a slow recovery from daytime water deficit, we studied the effect of repeated wetting of leaves during evening and night in

Photosynthetic limitation of similar-height Cryptomeria japonica trees growing at different rates
We compared light-saturated photosynthetic rates and their stomatal limitations among Cryptomeria japonica trees with a similar height but different current growth rates. Although slow-growing trees had a lower s...
