    Notes: The genetic mechanism underlying the relationship between three traits of the primary sink size - spikelet number per panicle (SNP), panicle number per plant (PN), and 1000-grain weight (GWT), and their 10 component traits in rice was dissected in 292 F13 recombinant inbred lines using a complete linkage map. A total of 43 genomic regions on 12 rice chromosomes were found to contain quantitative trait loci (QTLs) affecting the sink size traits, which revealed several important aspects of the genetic basis of sink capacity in rice. First, QTLs for SNP, PN and GWT were largely independent. Secondly, most QTLs affecting SNP and GWT showed close characteristics in both genomic locations and directions of effects to QTLs for their components, suggesting that pleiotropy, rather than linkage, was the primary genetic basis of the correlated panicle and grain traits. Thirdly, some QTLs affecting component traits did not contribute to SNP or GWT. In these cases, two or more QTLs with opposite effects on their component traits were detected, which could be due to either linkage or pleiotropy. Fourthly, some QTLs had large effects on panicle number (QPn4), panicle branching and length (QPbn3a, QPbn3b and QPb14), grain length and volume (QG13, QG15 and QGv2), and grain shape (QGs1 and QGs7), which were consistently detected in the related rice mapping populations and in different environments, providing good candidates and useful information for marker-aided improvement of sink size and yield potential of rice.

    Notes: Milling quality of rice grains is important to both producers and consumers. In this study, quantitative trait loci (QTLs) controlling brown rice rate (BR), milled rice recovery (MR) and head rice recovery (HR) were analysed by composite interval mapping over 2 years using 98 backcross inbred lines (BILs). A total of 12 QTLs for the three traits were detected, of which five were for BR, four for MR and three for HR. The proportion of phenotypic variation explained by individual QTLs ranged from 7.5 to 19.9%, and additive effects contributed by a single QTL accounted for 0.46 to 2.34% of the variation. QTL-by-environment interactions were observed by comparing QTL mapping of the same population grown in two consecutive years. Three of five QTLs for BR and two of four QTLs for MR were detected in 2 years, and all three QTLs for HR were detected in 1 year only. BR was significantly correlated with MR, and all four QTLs of MR were located in the same regions as those of BR. This indicated that QTLs for highly correlated traits could often be detected in the same interval.

    Notes: A pentaploid hybrid plant (2n= 50, AACCO) between Brassica napus (AACC) and Orychophragmus violaceus (OO) showed matroclinous morphology and some patroclinous characters. Cloned progenies were mixoploid, consisting of various cells with 38–53 chromosomes, half of the cells with 50 chromosomes. The 50 chromosomes were mainly paired as 25 bivalents and segregated as 25:25 or 22:28; many other segregations were observed in some cells. Progenies produced by selfing had 38–47 chromosomes. Plants with 38 chromosomes were cytologically stable; in all other plants the chromosome number of individual cells varied between the genotype-specific maximum number and 38, indicating loss of chromosomes during mitosis. The mixoploid plants with 44 chromosomes mainly produced two kinds of mixoploid progenies with 44 and 41 chromosomes, respectively. All plants with 2n= 38 had the same morphology as the parental B. napus and were normal in fertility. These chromosome pairings and segregations in the pentaploid and its progeny support the hypothesis that O. violaceus is a natural polyploid species with a basic chromosome number of 3.

    Palaeomagnetism of the Brewer Conglomerate in central Australia, and fast movement of Gondwanaland during the Late Devonian (1993)

    Notes: Palaeomagnetic analysis of 11 diamond-drill cores from the Late Devonian Brewer Conglomerate in the northeastern part of the Amadeus Basin, central Australia, yields three magnetic components: a drilling-induced remanence (C1) acquired during the industrial drilling process, a mid- to Late Carboniferous syndeformational overprint (C2) acquired during the Alice Springs Orogeny, and a primary remanence (C3). C3 passes a fold test and gives a latest Devonian pole (BC) at 47.1d̀S, 041.0d̀E with A95= 6.4d̀. The revised APWP for Gondwanaland requires West Gondwanaland to drift across the South Pole during the Late Devonian with a speed of ˜20cm yr-1, while East Gondwanaland remained at low-latitude positions. It is suggested that fast plate movement occurred far more often during the Palaeozoic than has previously been thought.

    Syn-deformational remanent magnetization of the Mount Eclipse Sandstone, central Australia (1989)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 99 (1989), S. 0 
    Details

    Topics: Geosciences
    Notes: The palaeomagnetism of the latest Devonian-Early Carboniferous Mount Eclipse Sandstone in central Australia reveals samples from 16 out of 31 sites having a consistent hightemperature component of natural remanent magnetization. Site-mean directions from the two limbs of the most detailed studied syncline attain their best grouping after 75 per cent of ‘unfolding’, and further ‘unfolding’ causes a ‘cross-over’ feature. Mineralogical studies using microscope and electron microprobe show that this remanance is most likely to be carried by secondary haematite formed by alteration of Fe-rich minerals during the midCarboniferous deformation. Four different models are examined to reconstruct the palaeohorizontal for the syn-deformational remanence. The best estimate of the palaeomagnetic South Pole position is lat. = 33.8°S, and long. = 121.2°E (dp = 19.2°, dm = 19.7°), close to Australia. This result indicates a rapid polarward movement of eastern Gondwanaland during the first half of the Carboniferous. We also suggest that the widespread Alice Springs Orogeny-related overprints in central Australia were acquired during the beginning of the main phase of deformation in the mid-Carboniferous.

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Orychophragmus violaceus, a member of the Cruciferae family, has been found to have a high oil quality with high contents of palmitic (14.3 %) and oleic (20.3 %) acids, and lower contents of linolenic (4.8 %) and erucic (0.9 %) acids. Plants of O. violaceus exhibit a high number of branches, pods per plant, and seeds per pod, which contributes to the high yield potential of this plant. Individual selection was made in the original population of O. violaceus, and a few early, disease-tolerant and high-yielding lines were obtained. Intergeneric hybridization was performed between B. napus and O. violaceus and several hybrid plants (F1) were obtained. After treatment with colchicine, amphidiploid plants developed. O. violaceus shows great potential for becoming an edible oil crop or being used as genetic material in a rapeseed breeding programme.

    Cloning and sequencing of the structural gene for the porin protein of Bordetella pertussis (1991)

    Notes: Bordetella pertussis produces a porin protein which is a prominent outer membrane component found in both virulent and avirulent strains. N-terminal amino acid analysis of purified B. pertussis porin was performed and this amino acid sequence was used to design an oligonucleotide that was then utilized to screen a λgt11 library containing randomly sheared fragments of DNA from B. pertussis strain 347. One clone, λBpPor, was identified and subcloned into pUC18. A portion of the DNA Insert in this subclone, pBpPor1, was sequenced and shown to contain the N-terminal region of the structural porin gene. This truncated gene sequence was used to design an additional oligonucleotide that was used to identify a clone, pBpPor2, which overlapped with pBpPor1 and contained a termination codon. The structural gene deduced from this sequence would encode a 365-amino-acid polypeptide with a predicted mass of 39103 daltons. The predicted product also contains a signal sequence of 20 residues that is similar to that found in other porin genes. The predicted B. pertussis porin protein sequence contains regions that are homologous to regions found in porins expressed by Neisseria species and Escherichia coli, including the presence of phenylalanine as the carboxy-terminal amino acid. DNA hybridization studies indicated that both virulent and avirulent strains of B. pertussis contain only one copy of this gene and that Bordetella bronchiseptica and Bordetella parapertussis contain a similar gene.

    Notes: Feeding ecology of three small fish species, Hypseleotris swinhonis, Ctenogobius giurinus and Pseudorasbora parva was studied seasonally in the Biandantang Lake, a small, shallow lake in central China. Gut length, adjusted for total body length, was significantly higher in spring than in other seasons for all the three species. Seasonal changes in gut length were not associated with changes in food quality. Weight of fore-gut contents, adjusted for body weight, was significantly higher in winter and spring than in summer and autumn in H. swinhonis and C. giurinus, and significantly higher in autumn than in spring and summer for P. parva. Percentage of empty fore-guts was highest in summer and lowest in spring for H. swinhonis and C. giurinus, and highest in winter and lowest in autumn for P. parva. Diet of the three small fishes showed apparent seasonal changes, and these changes reflected partly the seasonal fluctuations of food resources in environment. Diet breadth was high in winter and low in autumn for H. swinhonis, high in winter and low in spring and summer for C. giurinus, and high in autumn and low in spring for P. parva. Diet overlaps between pairs of species were biologically significant in most cases, except between H. swinhonis and P. parva in summer and autumn and between C. giurinus and P. parva in autumn.

    Dietary-morphological relationships of fishes in Liangzi Lake, China (2001)

    Notes: Species in Liangzi Lake were clustered into four trophic groups: Hemiramphus kurumeus and Hemiculter bleekeri bleekeri fed predominantly on terrestrial insects; Carassius auratus auratus and Abbottina rivularis on non-animal food; Hypseleotris swinhonis, Ctenogobius giurinus, Pseudorasbora parva and Toxabramis swinhonis on cladocerans or copepods; Culterichthys erythropterus on decapod shrimps. Gut length, mouth width, mouth height, gill raker length and gill raker spacing, varied widely among species. With the exception of three species pairs (H. swinhonis, C. giurinus; C. erythropterus, H. kurumeus; T. swinhonis, H. bleekeri bleekeri), principal components analysis of morphological variables revealed over-dispersion of species. Canonical correspondence analysis of dietary and morphological data revealed five significant dietary-morphological correlations. The first three roots explained 〉 85% of the total variance. The first root reflected mainly the relationship of gut length to non-animal food, with an increase in gut length associated with an increase in non-animal food. The second root was influenced strongly by the relationship of the gill raker spacing to consumption of copepods, with an increase in gill raker spacing associated positively with copepods in the diet. The third root was influenced by the relationship of mouth gape to consumption of fish and decapod shrimps, with an increase in mouth gape associated with more fish and decapod shrimps in the diet. These significant dietary-morphological relationships supported the eco-morphological hypotheses that fish morphology influence food use, and morphological variation is important in determining ecological segregation of co-existing fish species.
