    Deep seismic sounding studies in the north Cambay and Sanchor basins, India (1990)

    Notes: Deep seismic sounding (DSS) studies have been carried out in the north Cambay and Sanchor sedimentary basins in western India along three lines covering about 350km. Seismic refraction and wide angle reflection data, pertinent to the sedimentary basin as well as the deep crustal section, have been recorded from 41 shot points using a 60 channel DFS-V digital recording system with 200 m geophone spacing and 4 ms data sampling. Extensive modelling and interpretation of a large number of seismic record sections reveal four sub-basins in the sedimentary section along these lines. Maximum depth to the granitic/Proterozoic basement (P-wave velocity 5.9–6.0 km s-1) is about 5000 m in the north Sanchor and the Patan sub-basins and about 5600 m in the south Sanchor sub-basin. The deepest part of the sedimentary basin is delineated within the Gandhinagar sub-basin where the basement depth reaches 7700 m. The Deccan Traps (P-wave velocity 4.3–4.8 km s-1) form the base of the Tertiary sediments, almost in the entire study area except the extreme northern part. There is also some indication of the presence of sub-Trappean Mesozoic sediments along this profile. Within the sedimentary basin two horst features, one near Diyodar (the Diyodar ridge) and the other northwest of Mehsana (the Unhawa ridge), are indicated by the seismic data consistent with the tectonics of the region.The thickness of the upper crust in this region does not exceed 15 km (P-wave velocity reaching 6.3km s-1). A prominent low-velocity zone (velocity 5.5 km s-1) occurs in the depth range from 10.5 to 12.5 km. The lower crust consists of two layers of velocities 6.6–6.9 km s-1 and 7.3–7.4 km s-1, the discontinuity between them occurring at 23–25 km depth. The Moho discontinuity (PM velocity 8.0 km s-1) lies at a depth of 31–33 km. The high-velocity (7.3–7.4 km s-1) lower crustal layer represents underplating of the crust due to mantle upwelling and rifting with large-scale extrusion of the Deccan volcanics. The large thickness of the Tertiary sediments in the Cambay basin and a relatively thin crust in the region suggest further rifting during the Tertiary.

    Albugo candida staghead formation in Brassica juncea in relation to plant age, inoculation sites, and incubation conditions (1996)
    Oxford, U.K. and Cambridge, USA : Blackwell Science

    Notes: Maximum staghead formation was obtained in 26-day-old (growth stage [GS] 3.1) Brassica juncea plants by inoculating differentiating flower buds with a zoospore suspension of Albugo candida race 2 V; exposing apical meristem tissues by opening the flower buds with forceps proved more conducive to staghead formation. Inoculation of 35- and 45-day-old plants (GSs 4.1 and 5.0, respectively) produced fewer hypertrophies, mainly in isolated flowers. Inoculation of 7- and 13-day-old plants (GSs 1.0 and 2.1, respectively) did not produce any hypertrophied flowers, but did result in the production of hypertrophied branches at the first node on the main stem. In general, hypertrophies were initiated more readily under greenhouse conditions than in the growth chamber. Other Brassica hosts inoculated with A. candida race 2 V or 7 V at GS 31 showed similar rankings for staghead formation and leaf infection. The technique should prove useful in screening breeding lines for disease resistance, particularly staghead formation, the most damaging phase as far as yield loss is concerned.

    Notes: Interactions between three species of bacteria (Burkholderia cepacia, Pseudomonas chlororaphis and Pseudomonas fluorescens), an ectomycorrhizal fungus (Paxillus involutus), and three root pathogenic fungi (Fusarium moniliforme, Fusarium oxysporum and Rhizoctonia solani) were studied. Burkholderia cepacia significantly reduced the in vitro mycelial growth of P. involutus, whereas, B. cepacia, Ps. chlororaphis, Ps. fluorescens and P. involutus reduced the mycelial growth of F. moniliforme, F. oxysporum and R. solani. Culture filtrates of B. cepacia, Ps. chlororaphis, Ps. fluorescens and P. involutus reduced conidial germination and increased the formation of chlamydospores of F. moniliforme and F. oxysporum. Burkholderia cepacia also reduced the formation of ectomycorrhizal short roots by P. involutus on lodgepole pine (Pinus contorta) and white spruce (Picea glauca) seedlings 2 months after inoculation. However, no significance difference in mycorrhizal short roots was observed after 4 months. The fungicide Anchor (a mixture of carboxine and thiram) significantly reduced root rot severity and increased the survival of lodgepole pine seedlings grown in a growth mix infested with F. moniliforme, F. oxysporum and R. solani. Control of the diseases of white spruce caused by these pathogens was not as successful. Treatment of seeds with either B. cepacia or P. involutus alone significantly increased the survival of seedlings grown in a mix that was inoculated with F. moniliforme and reduced the root rot severity caused by F. moniliforme and F. oxysporum, but not R. solani. Higher seedling survival and lower root rot severity were observed when conifer seeds were concomitantly inoculated with one of the bacterial species, P. involutus and Anchor.

    Notes: Abstract The extraction of mercury(II) from chloride and thiocyanate solutions has been studied by tracer techniques using bis(2-ethylhexyl) sulphoxide (B2EHSO) in benzene as an extractant. These extraction data have been analyzed theoretically by taking into account complexation of the metal in the aqueous phase by inorganic ligands and plausible complexation in the organic phase. The results demonstrate that Hg(II) is extracted as HgX2 and HgX2·nB2EHSO (where X=Cl− or SCN− andn=1 or 2). The effect of the foreign ions on the extraction of Hg(II) has also been investigated.

    Notes: Agrobacterium tumefaciens -mediated transformation of soybean [Glycine max (L.) Merrill. cv. Jack] using immature zygotic cotyledons was investigated to identify important factors that affected transformation efficiency and resulted in the production of transgenic soybean somatic embryos. The factors evaluated were initial immature zygotic cotyledon size, Agrobacterium concentration during inoculation and co-culture and the selection regime. Our results showed that 8- to 10-mm zygotic cotyledons exhibited a higher transformation rate, as indicated by transient GUS gene expression, whereas the smaller zygotic cotyledons, at less than 5 mm, died shortly after co-cultivation. However, the smaller zygotic cotyledon explants were found to have a higher embryogenic potential. Analysis of Agrobacterium and immature cotyledon explant interactions involved two Agrobacterium concentrations for the inoculation phase and three co-culture regimes. No differences in explant survival or somatic embyogenic potential were observed between the two Agrobacterium concentrations tested. Analysis of co-culture regimes revealed that the shorter co-culture times resulted in higher explant survival and higher somatic embryo production on the explants, whereas the co-culture time of 4 days severely reduced survival of the cotyledon explants and lowered their embryogenic potential. Analysis of selection regimes revealed that direct placement of cotyledon explants on hygromycin 25 mg/l was detrimental to explant survival, whereas 10 mg/l gave continued growth and subsequent somatic embryo development and plant regeneration. The overall transformation frequency in these experiments, from initial explant to whole plant, was 0.03 %. Three fertile soybean plants were obtained during the course of these experiments. Enzymatic GUS assays and Southern blot hybridizations confirmed the integration of T-DNA and expression of the GUS-intron gene in the three primary transformants. Analysis of 48 progeny revealed that three copies of the transgene were inherited as a single Mendelian locus.

    Notes: Abstract Surveys were made at the end of the 1990 and 1991 growing seasons for root-inhabiting fungi in the genera Fusarium, Cylindrocarpon and Pythium from the roots of one year-old container-grown Douglas-fir and spruce seedlings grown under greenhouse conditions. In the 1990 survey of four nurseries, it was found that 61–97% of both Douglas-fir and spruce roots were colonized with Fusarium, Cylindrocarpon or Pythium. There were significantly (p≤0.05) more Douglas-fir roots than spruce roots colonized by Fusarium at all nurseries, however, there were significantly (p≤0.05) more spruce roots than Douglas-fir roots colonized by Cylindrocarpon and Pythium. Root colonization of Douglas-fir and spruce by the three fungal genera during 1991 varied from 0–82% at three nurseries, however, only at a south coastal nursery was there significantly (p≤0.05) more spruce than Douglas-fir roots colonized by Cylindrocarpon. Significantly more seedlings were infected in 1990 than in 1991. In 1991, there were few significant differences between Douglas-fir and spruce, in the percentage of seedlings with colonized roots and in the percentage of growth medium colonized by the fungi. However, there were significant differences between nurseries.

    Identification and cataloguing of genetic information for resistance to wheat leaf rust (1980)
    Springer

    Keywords: Triticum aestivum ; bread wheat ; Puccinia recondita ; leaf rust ; host-pathogen specificity ; disease resistance ; leaf rust genes

    Notes: Summary Specific host-pathogen relationship is used to derive genetic information for resistance in commercial cultivars. Twenty-two cultivars were classified into 12 groups based on their reactions to 13 leaf rust (Puccinia recondita) races of India. The cultivars in each group were matched with the Lr gene carrying lines to see which genes they might possess. Confirmation of this information was sought through pedigree analyses. (1) Agra local and NP4 do not seem to have any resistance genes. (2) C306 has gene Lr14a, and NP824 one of the genes Lr12, Lr13, Lr14a or Lr22. (3) kalyansona carries Lr13 and another additional gene not in study. (4) Chhoti Lerma, NP852, Pusa Lerma, Sharbati Sonora, Shera, UP301 form one group and carry Lr1. (5) Sonalika seems to have Lr2a, Lr11 and additional genes. (6) Hy.65 has Lr10. (7) HS1076-2 and HW135 have the genes Lr2a and Lr3do. (8) HW124 carries the genes Lr1 and Lr3do. (9) Safed Lerma has Lr1 and Lr17. (10) NP846 has the genes Lr1 and Lr15. (11) HB117-107, Janak, UP215 form one group and possess the genes Lr3do and Lr15. (12) Girija possesses the genes Lr10 and Lr15. Based on such grouping of commercial cultivars for resistance genes a ‘Catalogue’ system is advocated for the design of wheat breeding programmes like the development of multiline and multigene cultivars.
