    The James Clerk Maxwell telescope Legacy Survey of the Gould Belt: a molecular line study of the Ophiuchus molecular cloud (2015)
    Oxford University Press
    Details
    Publication Date: 2015-01-07
    Description: CO, 13 CO, and C 18 O J = 3–2 observations are presented of the Ophiuchus molecular cloud. The 13 CO and C 18 O emission is dominated by the Oph A clump, and the Oph B1, B2, C, E, F, and J regions. The optically thin(ner) C 18 O line is used as a column density tracer, from which the gravitational binding energy is estimated to be 4.5 x 10 39 J (2282 M km 2  s –2 ). The turbulent kinetic energy is 6.3 x 10 38 J (320 M km 2  s –2 ), or seven times less than this, and therefore the Oph cloud as a whole is gravitationally bound. 30 protostars were searched for high-velocity gas, with 8 showing outflows, and 20 more having evidence of high-velocity gas along their lines of sight. The total outflow kinetic energy is 1.3 x 10 38 J (67 M km 2  s –2 ), corresponding to 21 per cent of the cloud's turbulent kinetic energy. Although turbulent injection by outflows is significant, but does not appear to be the dominant source of turbulence in the cloud. 105 dense molecular clumplets were identified, which had radii ~0.01–0.05 pc, virial masses ~0.1–12 M , luminosities ~0.001–0.1 K km s –1  pc –2 , and excitation temperatures ~10–50 K. These are consistent with the standard Giant Molecular Cloud (GMC) based size–linewidth relationships, showing that the scaling laws extend down to size scales of hundredths of a parsec, and to subsolar-mass condensations. There is however no compelling evidence that the majority of clumplets are undergoing free-fall collapse, nor that they are pressure confined.

    Medical therapies for mood disorders alter the blood-brain barrier (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-07-24
    Description: The effects of amitriptyline, lithium, and electroconvulsive shock on cerebral permeability and blood flow were tested. These three treatments share in common (i) the ability to influence the functional activity of central adrenergic neurons by way of effects on the release, reuptake, or metabolism of norepinephrine and (ii) therapeutic efficacy in mood disturbances. Under control conditions, cerebral permeability increases linealy with increasing arterial partial pressure of carbon dioxide and hence cerebral blood flow. All three treatments altered this relationship in a manner consistent with their adrenergic effects. Amitriptyline potentiated this increase in cerebral permeability whereas lithium and electroconvulsive shock blunted this phenomenon. These results support the hypothesis that one function of central adrenergic neurons is regulation of the blood-brain barrier and raise the possibility that a related effect may underlie the clinical usefulness of such treatment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Preskorn, S H -- Irwin, G H -- Simpson, S -- Friesen, D -- Rinne, J -- Jerkovich, G -- GM15956/GM/NIGMS NIH HHS/ -- MH-00272/MH/NIMH NIH HHS/ -- NS17252/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Jul 24;213(4506):469-71.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7244645" target="_blank"〉PubMed〈/a〉

    Reference Quality Genome Assemblies of Three Parastagonospora nodorum Isolates Differing in Virulence on Wheat (2018)
    Genetics Society of America (GSA)
    Details
    Publication Date: 2018-02-09
    Description: Parastagonospora nodorum , the causal agent of Septoria nodorum blotch in wheat, has emerged as a model necrotrophic fungal organism for the study of host–microbe interactions. To date, three necrotrophic effectors have been identified and characterized from this pathogen, including SnToxA, SnTox1, and SnTox3. Necrotrophic effector identification was greatly aided by the development of a draft genome of Australian isolate SN15 via Sanger sequencing, yet it remained largely fragmented. This research presents the development of nearly finished genomes of P. nodorum isolates Sn4, Sn2000, and Sn79-1087 using long-read sequencing technology. RNAseq analysis of isolate Sn4, consisting of eight time points covering various developmental and infection stages, mediated the annotation of 13,379 genes. Analysis of these genomes revealed large-scale polymorphism between the three isolates, including the complete absence of contig 23 from isolate Sn79-1087, and a region of genome expansion on contig 10 in isolates Sn4 and Sn2000. Additionally, these genomes exhibit the hallmark characteristics of a "two-speed" genome, being partitioned into two distinct GC-equilibrated and AT-rich compartments. Interestingly, isolate Sn79-1087 contains a lower proportion of AT-rich segments, indicating a potential lack of evolutionary hotspots. These newly sequenced genomes, consisting of telomere-to-telomere assemblies of nearly all 23 P. nodorum chromosomes, provide a robust foundation for the further examination of effector biology and genome evolution.

    Notes: Field experiments at Lacombe on a Ponoka loam soil (9·6% organic matter) during 1982 and 1983 investigated the tolerance of spring wheat (Triticum aestivum L.) cv. Neepawa in a weed free situation to trifluralin applied at 0·0–3·0 kg ai ha−1 in the autumn or spring and incorporated to a depth of 10 cm. Rates of trifluralin above 1·0 kg ai ha−1 applied in the autumn or spring reduced the percent stand of wheat compared to an untreated control. Two weeks after emergence the crop showed 37 or 47% injury indicated by delayed growth, following application at 1·0 kg ai ha−1 in the autumn or spring, respectively. The wheat recovered throughout the course of the growing season. At harvest, trifluralin applied in the autumn or spring at rates below 1·0 kg ai ha−1 caused a yield increase while higher rates caused a yield decrease compared to the untreated control. Spring application caused a greater yield loss than autumn application. The tolerance of spring wheat to trifluralin at rates required for weed control (1·1 kg ai ha−1 or higher) on this soil type is marginal.

    Isotope methods for assessing plant available phosphorus in acid tropical soils (2003)

    Notes: Use of isotope methods to measure the availability of phosphorus (P) in soils that are well supplied with P is well established. We have evaluated such methods for acid tropical soils with very small P contents, which are less well studied. The isotopically exchangeable P in soil suspensions (E value) and that in plant growth experiments (L value) were measured in soils that had received varying amounts of P fertilizer in two field experiments in Colombia. We determined the E values over 4–5 weeks of equilibration allowing for the kinetics of isotope exchange. The decrease in radioactivity in the soil solution at a particular time, t, divided by that at the start (rt/R) was described by three parameters (r1/R, r∞/R, and a coefficient n) derived from the time course of isotopic exchange over 100 minutes. Values of Et were calculated either from measured values of rt/R or those extrapolated until 12 weeks. Agrostis capillaris was grown on the same soils labelled with carrier-free 33P-orthophosphate ions to obtain L values. Agreement between E values derived from measured and extrapolated values of rt/R was satisfactory, but errors in n and r∞/R limited the precision with which we could estimate E values. For most soils, the P concentrations in the soil solution were greater than the detection limit of the malachite green method (0.9 µg l−1) but smaller than its quantification limit (3.6 µg l−1). In the soils with the least available P, the P content of the seed limited the determination of the L value. The E values were strongly correlated, but not identical, with the L values measured for the same time of isotopic exchange. We conclude that these approaches are not precise enough to detect in these soils the ability of a plant to access slowly exchangeable forms of P or to quantify the mineralization of organic P. However, these isotope techniques can be used to estimate the total fraction of added fertilizer P that remains available to the plants.

    Notes: Abstract The effect of cogranulation with elemental sulfur (S) on the availability of phosphorus (P) from partially acidulated phosphate rock (PAPR) prepared from Christmas Island or Duchess phosphate rock (PR) was studied as part of a larger experiment examining factors affecting the agronomic effectiveness of PAPR sources. PAPRs cogranulated with (10% w/w) or without elemental S were compared at four rates of P (excluding controls) in the presence and absence of supplementary sulfate (SO4) from gypsum on a P-deficient pasture soil with no previous history of elemental S applications. Lucerne (Medicago sativa L., cv. CUF101) yields and P and S uptake were determined in six bulked harvests collected over a 2-year period. Large responses to P rates were recorded but only minor and inconsistent responses to SO4-S occurred during the experiment. In contrast, elemental S in PAPR granules resulted in greater lucerne yields and P and S uptake by lucerne tops; these effects, which did not appear until 6 months after application, were attributed to the acidulation of residual PR in PAPR granules by action of H2SO4 produced by the oxidation of elemental S. These effects increased with increasing rates of PAPR applied and were greater for the Christmas Island PAPRs and at the 50% acidulation rate. This was attributed to the development of a more prolific root system at the higher P rates and the higher levels of soluble P provided by 50% PAPRs which enabled plants to more fully exploit P solubilized from S-granulated PAPR products.
