From these, we hypothesized that the upper leaves should not be fully light-saturated even under direct sunlight, but instead should share the light limitation with the shaded lower-canopy leaves, so as to utilize strong sunlight efficiently. Supporting this prediction, within a canopy of H. tuberosus, both the degree of light saturation and EPZ004777 inhibitor LAUE were independent of light environment within a canopy, resulting in proportionality between the daily photosynthesis and the daily incident light among the leaves.”
“Arbuscular mycorrhizal fungi are the most
important members of soil microbial community in ecosystem. These useful organisms form an indespensible component of any fertile soil. It is said that a good quality of 1 kg soil is almost equal to 1 kg of gold. Symbiotic relationships of AMF provide an alternative
for survival of plants in highly stressed areas, this association helps in uptake of P as well as other minerals, maintain better water balance, increase plant biomass and produce growth promoting substances. Strategies to promote plantation in poor or degraded soil includes introduction of native AMF in soil. During present study a survey was undertaken in degraded forest areas with certain grasses in Godhra AICAR in vivo and Baria divisions, 115 kms from Vadodara city in India. Rhizospheric soil samples were collected from 22 different places. Soil samples of Heteropogon contortus showed more number of AM spores (220/100 g) as compared to that of Themeda triandra 165/100 g. Kalitalai soil samples
Chloris barbata showed more number of spores (150/100 g) than that of Rampara (110/100 g). The percentage occurence of AM spores was more in Bandheli. Analysis of AM spores resulted in identification of different species belonging to three genera i.e. Glomus, Gigaspora, TGF beta inhibitor and Acaulospora.”
“During each cell cycle, the mitotic spindle is efficiently assembled to achieve chromosome segregation and then rapidly disassembled as cells enter cytokinesis. Although much has been learned about assembly, how spindles disassemble at the end of mitosis remains unclear. Here we demonstrate that nucleocytoplasmic transport at the membrane domain surrounding the mitotic spindle midzone, here named the midzone membrane domain (MMD), is essential for spindle disassembly in Schizosaccharomyces pombe cells. We show that, during anaphase B, Imp1-mediated transport of the AAA-ATPase Cdc48 protein at the MMD allows this disassembly factor to localize at the spindle midzone, thereby promoting spindle midzone dissolution. Our findings illustrate how a separate membrane compartment supports spindle disassembly in the closed mitosis of fission yeast.”
“A gamma-aminobutyric acid (GABA)-producing microorganism was isolated from jeot-gal (anchovy), a Korean fermented seafood. The isolate, A156, produced GABA profusely when incubated in MRS broth with monosodium glutamate (3% (w/v)) at 37 degrees C for 48 h.
