The Arabidopsis thaliana K+ channel KAT1 has been suggested to have a key role in mediating the aperture of stomata pores on surface plant leaves. Although activity is thought be regulated by phosphorylation, endogenous pathway and primary target site for this modification remained unknown. In present study, we demonstrated that C-terminal region acts as phosphorylation calcium-independent ABA (abscisic acid)-activated protein kinase SnRK2.6 (Snf1-related 2.6). This was confirmed LC-MS/MS...
In our search for compounds that inhibit the binding of [ 3 H]‐substance P (SP) to guinea‐pig lung membranes, dipeptide SP antagonist, FK888, was developed by chemical modification parent compound, ( d ‐Pro 4 , ‐Trp 7,9,10 Phe 11 )SP 4– . a H]‐SP assay using membranes and rat brain cortical synaptic FK888 displaced with K i value 0.69 ± 0.13 n m 0.45 0.17 μ respectively, in competitive manner. inhibited contraction isolated ileum induced presence atropine indomethacin (a NK 1 receptor...
Abstract We report the first study of sperm whale‐fall ecosystems, based on mass sinking whale carcasses at shelf depths in northwest Pacific. conducted three observations over a 2‐year period replicate sperm‐whale implanted 219–254 m off southern part Japan from July 2003 to August 2005. The was made possible by stranding whales January 2002, and subsequent 12 waters Cape Nomamisaki. Dense aggregations unique chemosynthesis‐based fauna had formed around after 18 months (July 2003). mytilid...
Increases in rates of individual leaf photosynthesis (Pn) are critical for future increases yields rice plants. Although many efforts have been made to improve Pn with transgenic technology, the desired not yet achieved. Two lines extremely high values were identified among backcrossed inbred derived from indica variety Takanari, one most productive varieties Japan, and elite japonica Koshihikari (Koshihikari/Takanari//Takanari). The two at an ambient CO2 concentration 370μmol mol–1 as well...
The seedlings of Oryza sativa L. cv. Nipponbare grown by hydroponic culture for 3 wks were treated with 75, 100, 150 and 200 mM NaCl 14, 6 days, respectively, examined chloroplast ultrastructure in the region where chlorophyll fluorescence had been recorded. treatment decreased ratio variable to maximum yield (Fv/Fm) caused swelling thylakoids. thylakoids was quantified percentage length swollen total This value increased increasing concentration. Although Fv/Fm at all concentrations NaCl,...
Since marine medusae and ctenophores harbor a wide variety of symbionts, from protists to fish, they constitute unique community in pelagic ecosystems. Their symbiotic relationships broadly range simple, facultative phoresy through parasitisim complex mutualism, although it is sometimes difficult define these associations strictly. Phoresy and/or commensalism are found symbionts such as pycnogonids, decapod larvae fish juveniles. Parasitism parasitoidism common the following symbionts:...
Chloroplast protrusions (CPs) are often observed under environmental stresses, but their role has not been elucidated. The formation of CPs was in the leaf rice plants treated with 75 mm NaCl for 14 d. Some were almost separated from main chloroplast body. In some CPs, inner membrane structures and crystalline inclusions included. Similar surrounded by double membranes cytoplasm vacuole. Ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) detected similar These results suggest that CP...
Rationale: It is well established that the migration and proliferation of vascular smooth muscle cells (VSMCs) have major roles in remodeling process. Our previous study showed Akt substrate Girdin, which expressed VSMCs endothelial cells, essential for postnatal angiogenesis. However, function Girdin its Akt-mediated phosphorylation their vivo remain to be elucidated. Objective: We investigated using cultured animal models remodeling. Methods Results: The depletion by RNA interference...
SummaryHigh concentrations of NaCl significantly reduced the fresh and dry weights lengths roots shoots. exhibited a more rapid effect in water culture than soil culture. In both solid cultures, root growth was suppressed severely shoot growth. Electron microscopic studies revealed that caused swelling thylakoids, accumulation starch grains lipid droplets, distortion grana stacking, increase size number plastoglobuli vesiculation cellular membrane. Mitochondria became deficient cristae,...
We investigated the mechanisms of increased sensitivity to Na+ in apical and basal regions rice leaf under salinity. Three-week-old plants were treated with 200 mM NaCl hydroponic culture for 3 d. Segments 6 cm length obtained from fully expanded uppermost leaves (6th blades) as old young tissues, respectively. In exposed NaCl, Nitro blue tetrazolium (NBT) reducing activity, H2O2 Malondialdehyde (MDA) contents significantly increased, accompanied by swelling thylakoids destruction thylakoid...
In C(4) plants, mesophyll (M) chloroplasts are randomly distributed along the cell walls, while bundle sheath (BS) typically located in either a centripetal or centrifugal position. We investigated whether these intracellular positions affected by environmental stresses. When mature leaves of finger millet (Eleusine coracana) were exposed to extremely high intensity light, most M aggregatively re-distributed BS side, whereas arrangement was unaffected. Compared with homologous...

The membranes of Zea mays (maize) mesophyll cell (MC) chloroplasts are more vulnerable to salinity stress than those bundle sheath (BSC) chloroplasts. To clarify the mechanism underlying this difference in salt sensitivity, we monitored changes glycerolipid and fatty acid compositions both types chloroplast upon exposure stress. monogalactosyldiacylglycerol (MGDG) digalactosyldiacylglycerol (DGDG) contents were higher MC BSC chloroplasts, presence absence treatment. Under conditions, MGDG...
Jellies play a fundamental role in the oceans, inhabiting whole ecosystem from surface down through midwater (twilight zone, 50-1000m, and bathypelagic, 1000-4000m). Recent best estimates suggest that gelatinous zooplankton account for 30% of total plankton biovolume. However, these are most likely drastic underestimate. A barrier to quantifying jellies biogeochemical cycles currently used sampling techniques. There is pressing need accurately quantify contribution biovolume, which...
Synechococcus sp. PCC7942 cells transformed with Escherichia coli bet genes accumulated glycinebetaine (to about 80 raM) and acquired an increased tolerance to salt stress. Ribulose 1,5-bisphosphate carboxylase activity in the extract from control was found decrease more rapidly than that of either PSI or PSII under We examined levels transcript, protein enzyme ribulose determine at which level is affected early stages The rbcL mRNA both def-containing around two-fold stress compared those...
summary Embryogenically competent callus was induced from in vitro grown Saccharum officinarum L. (NCo 310) plantlets by plating young leaf segments on MS basal medium supplemented with 30 μM dicamba for 21 d darkness, and subsequently transferring to a (EFDM) which embryos could form develop. Embryogenic response improved if the EFDM 1 or 5 dicamba, casein hydrolysate (1 g −1 ), 6% maltose 6–9% corn syrup. Calli maintained their embryogenic competence up 16 months under these conditions,...
AbstractWe investigated the kinds of active oxygen species leading to destruction chloroplast ultrastructure in salt-stressed rice plants. After seedlings were grown for 3 wks, leaf segments (5 mm square) cut from middle portion 5th leaves. Leaf incubated 200 mM NaCl under dark or light conditions 24 hr. The chlorophyll content drastically decreased between 12- and hr NaCl, but, no reduction was observed dark. In electron microscopic studies, caused swelling thylakoids thylakoid membranes...
