    Notes: Abstract Spiroplasmas are members of the Class Mollicutes, wall-less prokaryotes having a high adenosine–thymidine content in their small genomes. Spiroplasma citri is a plant pathogen that inhabits phloem. Like other phytopathogenic spiroplasmas and the related phytoplasmas, it is transmitted from plant to plant by phloem-feeding leafhoppers that serve as alternate hosts for the spiroplasma as well as vectors. Genetic information in spiroplasmas is carried on a circular chromosome, on plasmids and/or in virus genomes. A picture emerging from recent research on the S. citri genome is one of frequent and often extensive variation, resulting from a number of different mechanisms. Expansion and contraction events must continually be occurring in about equal proportions so that the net genome size varies within defined boundaries. Particularly impressive are large changes in genome size that can occur in only a few generations. As with most organisms, genetic variation in S. citri results from variation in extrachromosomal DNA content, changes due to DNA replication and repair processes and changes due to recombination. The implied flux of genetic information into and out of the S. citri genome should be beneficial to the bacterium, allowing it, with its small genome size, to adapt to new environments.

    Description / Table of Contents: Samenvatting Eenenzeventig zaadmonsters van 23 soorten van de Papilionaceae en 17 andere soorten werden verzameld en naar laboratoria in Australië, Nieuw Zeeland, Nederland en de Verenigde Staten van Amerika gezonden. In elk van deze landen werden de uit de zaden verkregen planten op hun vatbaarheid voor acht door bladluizen op persistente wijze overgebrachte virussen getoetst. Het betrof de volgende virussen: ‘beet western yellows virus’ (BWYV) vanGlycine max uit Illinois, ‘legume yellows virus’ (LYV) uit Californië, een virus vanMedicago sativa uit Michigan (MiAV), twee virussen die bladrol en topvergeling inPisum sativum veroorzaken, één uit Nieuw Zeeland (PeLRV-NZ) en één uit Nederland (BLRV), isolaten van het ‘subterranean clover red leaf virus’ uit Nieuw Zeeland (SCRLV-NZ) en Tasmanië (SCRLV-T) en ‘subterranean clover stunt virus’ (SCSV). De verwantschap tussen de acht genoemde virussen, zoals blijkend uit de reacties van de verschillende waardplanten, werd vastgesteld met behulp van een computerprogramma voor classificatie. SCRLV-NZ en SCRLV-T vertoonden de meeste verwantschap. Beide hadden een tamelijk grote waardplantenreeks, waaronder enkele soorten die niet behoorden tot de vlinderbloemigen. BMYV en PeLRV-NZ vormden een tweede groep. Zij waren typisch voor de meeste stammen van het ‘beet western yellows virus’ in zoverre zij de toetsplantenBrassica napus, Capsella bursa-pastoris enStellaria media konden infecteren. MiAV en BLRV vormden eveneens een paar. Zij veroorzaakten meestal verschillende typen symptomen op de vatbare waardplanten. De waardplantenreeks was beperkt tot de Leguminosae. Alleen kon BLRV ookClaytonia perfoliata enErodium spp. infecteren. De mate van verwantschap tussen LYV en SCSV was niet eenduidig. Uit bepaalde eigenschappen zou tot onderlinge verwandtschap besloten kunnen worden, uit enkele andere echter zou meer een verwantschap tussen SCSV en SCRLV worden vermoed. De waardplantenreeks van LYV en SCSV was beperkt tot de Leguminosae; beide veroorzaakten hevige symptomen in hun waardplanten en konden moeilijk worden geïsoleerd uit geïnfecteerde planten. LYV vertoonde enige verwantschap met BLRV en MiAV. Op grond van de resultaten van de proeven kon een groep van toetsplanten worden samengesteld, die zeer bruikbaar is voor de virusvermeerdering en voor de identificatie van de genoemde acht virussen. Twee van de toetsplanten, nl.P. sativum enTrifolium subterraneum cv. Bacchus Marsh bleken vatbaar voor alle isolaten. Tien andere, nl.Arachis hypogea, Beta vulgaris, C. bursa-pastoris, G. max cv. Shirotsurunko,Gomphrena globosa, lactuca sativa, Lens esculenta cv. 179307,M. sativa cv. Washoe,Phaseolus vulgaris cv. Canadian Wonder enTrifolium hybridum zijn geschikt voor onderscheiding van alle genoemde isolaten.
    Notes: Abstract Seventy one seed-lines representing 23 species of papilionoid legumes and 17 species of nonlegumes were collected and distributed to four countries; Australia, New Zealand, the Netherlands and the U.S.A. In each of these countries plants were grown from the seeds and their susceptibility to a total of eight persistent aphid isolates transmitted viruses was assessed. The viruses were a strain of beet western yellows (BWYV) fromGlycine max in Illinois, legume yellows (LYV) in California and a virus in Michigan (MiAV) fromMedicago sativa, fromPisum sativum causing leaf roll and top yellows in New Zealand (PeLRV-NZ) and the Netherlands (BLRV), isolates of subterranean clover red leaf from New Zealand (SCRLV-NZ) and Tasmania (SCRLV-T), and subterranean clover stunt (SCSV) from Tasmania. The relationships between the eight viruses as indicated by their host reactions were assessed using computer classification techniques. SCRLV-NZ and SCRLV-T were the most similar. They had moderately wide host ranges that included some non-legumes. A second group comprized BWYV and PeLRV-NZ. These were typical of most beet western yellows virus strains in that they infectedBrassica napus, Capsella bursa-pastoris andStellaria media. MiAV and BLRV also formed a pair. They generally induced severe symptoms on the hosts which they infected and had host ranges confined to legumes except that BLRV also infectedClaytonia perfoliata andErodium spp. The relationships of LYV and SCSV were not consistent. They paired together in some classifications, but SCSV sometimes grouped with the SCRLV isolates. Both had host ranges confined to legumes, caused severe symptoms in most hosts and were often difficult to recover from affected plants. LYV had some affinities with BLRV and MiAV. The tests indicated a set of test plants which were most useful for propagating and identifying persistent aphid-transmitted viruses from legumes. Two,P. sativum cv. Onyx andTrifolium subterraneum cv. Bacchus Marsh were susceptible to all isolates. Ten others distinguished between the isolates and wereArachis hypogea, Beta vulgaris, C. bursa-pastoris, G. max cv. Shirotsurunoko,Gomphrena globosa, Lactuca sativa, Lens esculenta cv. 179307,M. sativa cv. Washoe,Phaseolus vulgaris cv. Canadian Wonder andTrifolium hybridum.

    Notes: Abstract Phase relations in the lime-rich portion of the system CaO-B2O3-SiO2 have been studied by microscopy, infrared spectroscopy and X-ray powder diffraction of heated mixtures and quenched charges. Extensive solid solution of B2O3 in Ca2SiO4 occurs along the Ca2SiO4-Ca3B2O6 boundary, which has been studied in detail. It contains a ternary compound, Ca11B2Si4O22, which is stable to liquidus temperatures, melting incongruently to Ca2SiO4 and liquid at 1420 °C. Ca11B2Si4O22forms a eutectic with Ca3B2O6 at 1400 °C and, in the ternary system, with CaO and Ca3B2O6 at 1390 °C.

    Notes: Abstract Methionine sulfoximine provided at a concentration which inhibits photosynthesis in intact leaves (10 mM) had no significant influence on the rate of photosynthesis of isolated pea leaf chloroplasts. In contrast, ammonium, 3-(3,4-dichlorophenyl)-1,1-dimethylurea, and D,L-glyceraldehyde all strongly inhibited the photosynthesis of isolated chloroplasts. We conclude that low concentrations of methionine sulfoximine (up to 10 mM) have no direct effect on the photosynthetic process.

    Notes: Summary Cultivars of tomatoes, cucumbers, lettuce and peppers have been bred for resistance to one or more pathogens. Some tomato and cucumber cultivars have resistance to a wide range of diseases. Resistance has been transient in many cases and a succession of cultivars with new genes or new combinations of resistance genes has been necessary to maintain control. There has been a number of notable exceptions and these have included durable resistance to such pathogens asFulvia fulva and tomato mosaic virus. With lettuce the resistance situation is complicated by the occurrence of fungicide resistant pathotypes. There are no strains ofAgaricus bisporus purposely bred for disease resistance. In protected flower crops only resistance to Fusarium wilt in carnations has been purposely bred but differences in disease resistance are apparent in cultivars of many ornamental crops. This is particularly so in chrysanthemums where there are cultivars with resistance to many of the major pathogens. Similar situations occur with other flower crops and pot plants. Cultivars of some species have not been systematically investigated for resistance. The need for genetic resistance will increase with the further reduction, in the limits on pesticide use and an increasing public awareness and importance of pesticide pollution.
