Changes in leaf water relations under water stress were examined. In experiment 1, water stress was imposed by withholding irrigation to potted seedlings of deciduous oak, Quercus crispula and Q. serrata. Changes in the pressure–volume (P–V) curve in mature leaves were followed. The leaf water potential at turgor loss (Ψl,tlp) significantly decreased after 13 d of drought treatment. The bulk elastic modulus (?) significantly decreased, which contributed to the maintenance of cell turgor together with the decrease in osmotic potential. In experiment 2, water stress was imposed by notching a branch of a Q. serrata tree. After the notching, the daily minimum leaf water potential (Ψl) decreased, and a significant decrease in Ψl,tlp was observed 15 d after notching. The osmotic potential at water saturation (Ψπ,sat) did not decrease significantly until 25 d after notching whereas, ? had already decreased significantly within 15 d after notching and increased promptly after substantial precipitation. It was confirmed that ? of mature leaves decreased reversibly in water stress. This response of ? was more rapid than that of the osmotic potential and, thus, effectively maintained cell turgor when water stress was suddenly imposed on the leaves. 相似文献

The anesthetic mixture of medetomidine (MED), midazolam (MID) and butorphanol (BUT)
produced anesthetic duration of around 40 minutes (min) in ICR mice. We reported that this
anesthetic mixture produced almost the same anesthetic effects in both male and female
BALB/c and C57BL/6J strains. Intraperitoneal (IP) administration of drugs has been widely
used in mice. However, various injectable routes of the anesthetic mixture may cause
different anesthetic effects. First, we examined effects of the anesthetic mixture by
subcutaneous (SC) and intravenous (IV) injection compared to IP injection. After injection
of the anesthetic mixture, administration of atipamezole (ATI) induced mice recovery from
anesthesia. Secondly, we examined how different dosage and optimum injection timing of ATI
affected mice recovery from anesthesia. We used an anesthetic score to measure anesthetic
duration and a pulse oximeter to monitor vital signs under anesthesia. Usually, drugs from
SC injection work more weakly than IP or IV injection. However, we found no significant
differences of anesthetic duration among the three different injection routes.
Antagonistic effects of ATI (0.3 mg/kg and 1.5 mg/kg) worked equally when administered at
30 min after injection of the anesthetic mixture. Antagonistic effects of ATI (1.5 mg/kg)
were stronger than ATI (0.3 mg/kg) at 10 min after injection of the anesthetic mixture.
The anesthetic mixture is a useful drug to induce nearly the same anesthetic effects by
different injection routes and has an antagonist of ATI which helps mice quickly recover
from anesthesia. These results may contribute to the welfare of laboratory animals. 相似文献

ABSTRACT. Small GTPase Rab (products of ras genes from rat brain) is a widely conserved molecular switch among eukaryotes and regulates membrane trafficking pathways. It is generally considered that the number of Rab encoded in the genome correlates with multicellularity; however, we found that unicellular ciliates Tetrahymena thermophila (Tt) and Paramecium tetraurelia (Pt) possess many more Rab genes in their genome than the 64 HsRab genes in the human genome. We succeeded in isolating 86 cDNA clones of 88 TtRab genes in the Tetrahymena genome. By comparing the amino acid sequence of Rab in humans and the budding yeast Saccharomyces cerevisiae, 42 TtRab belonged to subfamilies functionally characterized and designated as conventional Rab, while the remaining 44 TtRab were considered to be species‐specific. To examine the diversity of Rab in ciliates, we searched for Rab genes in the genome database of P. tetraurelia. Overall, 229 PtRab genes were found and categorized as 157 conventional and 72 species‐specific PtRab, respectively. Among them, nine PtRab genes showed high homology to seven TtRab, suggesting the conservation of ciliate‐specific Rab. These data suggested that the range of Rab is markedly amplified and diversified in ciliates, which may support the elaborate cellular structures and vigorous phagocytosis of those organisms. 相似文献

Acer capillipes is an insect‐pollinated tree species that grows in temperate regions of Japan. We isolated seven polymorphic microsatellite loci from this species using a dual‐suppression polymerase chain reaction (PCR) technique. The number of alleles per locus ranged from two to 10, and the expected heterozygosity ranged from 0.042 to 0.828. Cross‐species amplification from 14 other Acer species was successful for the majority of the isolated loci, suggesting that these loci may be useful for the characterization of other maple species. 相似文献

Pinus merkusii is an important industrial species that is distributed only in Southeast Asia. We isolated 10 microsatellite markers from this species using a dual‐suppression‐polymerase chain reaction technique. Of these markers, five loci were codominant and polymorphic. The number of alleles per locus ranged from three to six and the expected heterozygosity ranged from 0.389 to 0.728. These microsatellite markers will be available for analysis on population genetics and mating patterns. 相似文献
