Reid; Akio Furukawa; Tetsuro Mimura, The concentration of ions in plant cells and tissues is an essential factor in determining physiological function. In the present study, we established that concentration gradients of mobile ions exist in both xylem exudates and tissues within a barley (Hordeum vulgare) primary leaf. For K+ and NO3-, ion concentrations generally decreased from the leaf base to the tip in both xylem exudates and tissues. Ion gradients were also found for Pi and Cl- in the xylem. The hydathode strongly absorbed Pi and re-translocated it to the rest of the plant, whereas Cl- was extruded. The ion concentration gradients developed early during leaf growth, increased as the tissue aged and remained under both high and low transpiration conditions. Measurement of the expression profiles of Pi, K+ and NO3- transporters along the longitudinal axis of the leaf revealed that some transporters are more expressed at the hydathode, but for most transporters, there was no significant variation along the leaf. The mechanisms by which longitudinal ion gradients develop in leaves and their physiological functions are discussed. © 2013 John Wiley & Sons Ltd., Oct. 2013, 36, 10, 1826, 1837, Scientific journal, 10.1111/pce.12090

The transition is completely prevented by further supplementation of myo-inositol at the start of cultivation. The addition of ethanol caused an increase in membrane fluidity during the process of depolarization, and then fluidity was gradually lowered to the level equivalent with that of the stationary-phase yeast cells in accordance with filamentation. The increase in membrane fluidity of ethanol-induced cells appeared parallel with reduction in the content of membrane phosphatidylinositol, which was rich in saturated palmitic acid. Introduction of exogenous myo-inositol or 1 m sorbitol into the ethanol-supplemented culture at the start of cultivation restored yeast growth and the reduction of membrane fluidity occurred, coupled with the recovery of the phosphatidylinositol content., Aug. 2010, 56, 4, 321, 329, Scientific journal

The development and disintegration of phragmoplasts in the living cultured cells could be successively observed by detecting the green-fluorescent protein fluorescence of the microtubules. In the early telophase spindle, where two kinetochore groups and two daughter chromosome groups had completely separated from one another, fluorescence appeared in the interzone between the two chromosome groups. The fluorescent region was gradually condensed at the previous equator and increased in fluorescence intensity, and finally it formed the initial phragmoplast. The initial phragmoplast moved from the cell center towards the cell periphery, and it lost fluorescence at its center and became double rings in shape. The expansion orientation of the phragmoplast was not always the same as that of the future new cell wall before it came in contact with the cell wall. The phragmoplast did not usually come in contact with the cell wall simultaneously with its entire length. A portion of the phragmoplast which was earlier in contact with the cell wall disappeared earlier than other portions of the phragmoplast. The duration of contact between any portions of the phragmoplast and the plasma membrane of the cell wall was 15-30 min. The fluorescence intensity of the cytoplasm did not seem to be elevated by the disintegration of the strongly fluorescent phragmoplast., 2003, 220, 3-4, 111, 118, Scientific journal, 10.1007/s00709-002-0049-0

• Refereed, CELL STRUCTURE AND FUNCTION, JAPAN SOC CELL BIOLOGY, Ca2+ signal is generated only once in the mating pheromone response pathway in Saccharomyces cerevisiae, J Nakajima-Shimada; S Sakaguchi; F Tsuji; Y Anraku; H Iida, The mating pheromone, alpha-factor, of the yeast Saccharomyces cerevisiae binds to the heterotrimeric G protein-coupled cell surface receptor of MATa cells and induces cellular responses necessary for mating. In higher eukaryotic cells, many hormones and growth factors rapidly mobilize a second messenger, Ca2+, by means of receptor-C protein signaling. Although striking similarities between the mechanisms of the receptor-G protein signaling in yeast and higher eukaryotes have long been known, it is still uncertain whether the pheromone rapidly mobilizes Ca2+ necessary for early events of the pheromone response. Here we reexamine this problem using. sensitive methods for detecting Ca2+ fluxes and mobilization, and find no evidence that there is rapid Ca2+ influx leading to a rapid increase in the cytosolic free Ca2+ concentration. In addition, the yeast PLC1 deletion mutant lacking phosphoinositide-specific phospholipase C, a hey enzyme for generating Ca2+ signals in higher eukaryotic cells, responds normally to the pheromone. These findings suggest that the receptor-G protein signaling does not utilize Ca2+ as a second messenger In the early stage of the pheromone response pathway, Since the receptor-G protein signaling does stimulate Ca2+ influx after early events have finished and this stimulation is essential for late events in the pheromone response pathway {Iida et al,, (1990) J, Biol, Chem., 265: 13391-13399} Ca2+ may be used only once in the signal transduction pathway in unicellular eukaryotes such as yeast., Apr. 2000, 25, 2, 125, 131, Scientific journal

Growth regulation by altered extracellular and intracellular free Ca2+ concentrations, Shuichi Sakaguchi; Kyoko Shibuya; Hidetoshi Iida; Yasuhiro Anraku; Takahito Suzuki, The dimorphic fungus Candida albicans has both a yeast form and a hyphal form. When yeast-form cells were starved and then transferred to a N-acetylglucosamine medium, the formation of true hyphae from the unbudded yeast-form cells was induced. Removal of Ca2+ from the medium with EGTA inhibited hyphal formation by 50%, resulting in only thin and short hyphae. Externally applied excess Ca2+ (> 10-2 M) also affected the hyphal formation, resulting in formation of pseudohyphae. This effect required a high concentration of Ca2+ but was Ca2+-specific. Deprivation of Ca2+ also inhibited yeast-form growth. Interestingly, such cells had abnormally wide bud necks and became defective in cell separation. To measure cytosolic free Ca2+, fura-2 was introduced into hyphal cells by electroporation. Its normal value was estimated to be about 100 nM. The electroporation caused transient elevation of cytosolic free Ca2+ concentration and transient cessation of hyphal growth. There was a close correlation between the timing of recovery of Ca2+ concentration and that of the resumption of hyphal growth. Our results demonstrate the importance of extracellular and intracellular free Ca2+ for the growth of C. albicans., 1997, 38, 2, 215, 225, Scientific journal, 10.1007/BF02460856

• Not Refereed, PROTOPLASMA, SPRINGER-VERLAG WIEN, Overproduction of Cdc24p (Cls4p), a guanine nucleotide-exchange factor toward Cdc42 GTPase, impairs initiation of budding in Saccharomyces cerevisiae, S Sakaguchi; S Miyamoto; H Iida; T Suzuki; Y Ohya; Y Anraku, An entire coding region of the CDC24/CLS4 gene and its truncated derivatives were overexpressed in yeast cells under the control of the GAL1 promoter. Western blotting analysis of the yeast cell lysates showed that the CDC24/CLS4 protein (Cdc24p) was induced to reach its maximum level after 9 h incubation of the cells in galactose medium. Overexpression of Cdc24p within the cells caused the morphological change, accumulating large spherical unbudded cells which exhibited actin cytoskeleton disturbed, chitin delocalized on the cell surface, and cell viability decreased. Multiple nuclei were observed in these cells, indicating that only budding cycle bur not nuclear division cycle is blocked by the overproduction of Cdc24p. In order to identify the region of Cdc24p responsible for the growth inhibition, several truncated CDC24 genes were expressed. Surprisingly, overexpression of fragments either containing the C-terminal 76 amino acid residues or deleting the same region inhibited cellular growth. This suggests that Cdc24p contains multiple functional domains for its tasks, likely cooperating signals of bud positioning and bud timing., 1995, 189, 3-4, 142, 148, Scientific journal

The DNA content of the prototrophic fusion product obtained following fusion between strains 1006 and A5153 approximated to the sum of those of the parents, but was variable when NARA2 was used as the parent for fusion. Chromosome-sized DNA molecules of the fusion derivatives were separated by pulsed-field gel electrophoresis to examine whether either or both of the chromosome-sized DNA molecules of each parent were transferred into the fusion derivatives. In the fusion derivatives obtained following fusion between strains 1006 and A5153, nearly the full complement of chromosomes was shown to be transferred, but partial transfer of chromosomes occurred in the fusion derivatives that were obtained following fusion between strains NARA2 and A5153. Results indicated that chromosome loss also occurred when these two strains were fused. Variations in the size of R chromosomes, the rDNA-containing chromosomes, were observed in all fusion derivatives tested, indicating high-frequency recombination between R chromosomes during the fusion process., Dec. 1994, 140, 3319, 3328, Scientific journal

In the case of the temperature-dependent type of variants, high-ploidy cells appeared at 37 degrees C but rarely at 28 degrees C. This phenotype was named Pld(ts) (temperature-sensitive polyploidization), and the temperature-independent phenotype was called Pld(-). The appearance of high-ploidy cells in the culture of the Pld(ts) strain at 37 degrees C was accompanied by a significant increase in the frequency of auxotrophic variants; these variants probably occur as a result of segregation of auxotrophic markers from the heterozygous to the homozygous state. Both Pld(ts) and Pld(-) phenotypes were recessive in a fusion with a Pld(+) parent. An adenine auxotrophic marker (ade1) was introduced into a Pld(ts) strain in a heterozygous state, and the individual high-ploidy cells of this strain, grown at 37 degrees C, were micromanipulated to form colonies, which consisted of red and white sectors appearing at high frequency on a pink background. When the ade1 auxotrophy was introduced into Pld(-) strains, frequently sectored colonies were produced. These results suggested an increased level of chromosome missegregation in both types of Pld mutants. Analyses by pulsed-field gel electrophoresis of Ade(-) segregants, derived from a micromanipulated high-ploidy cell of a Pld(ts) strain, suggested the occurrence of nonreciprocal recombination, some of which includes chromosome loss., Jun. 1994, 176, 11, 3345, 3353, Scientific journal
