Genetic structure of an endemic Japanese conifer, Sciadopitys verticillata (Sciadopityaceae), by using microsatellite markers.

We investigated the genetic structure of Sciadopitys verticillata, an endemic conifer in Japan, using 11 microsatellite markers. Average expected heterozygosity varied from 0.282 to 0.

Stromal over-reduction by high-light stress as measured by decreases in P700 oxidation by far-red light and its physiological relevance.

The oxidation level of P700 induced by far-red light (DeltaA(FR)) in briefly dark-treated leaves of some sun plants decreased during the daytime and recovered at night. The dark recovery of decreased DeltaA(FR) proceeded slowly, with a half-time of about 5 h. We propose that stromal over-reduction induced by sunlight was the direct cause of the depression of DeltaA(FR).
