    Keywords: Angiosperms ; Leguminosae ; Fabaceae ; Caesalpinioideae ; Mimosoideae ; Faboideae ; Phaseolus coccineus ; Serological systematics ; seed proteins ; phytohaemagglutinin ; vicilin ; phaseolin
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract An immunosystematical research was conducted on the seed proteins of 32 species ofFabaceae. By comparing all immunelectrophoretic patterns with the self reaction of a reference system (Phaseolus coccineus) all proteins detected have been identified and their distribution within the family has been analyzed. Half of the proteins identified inP. coccineus gave positive cross reactions with proteins present in all other species. Among this group are “protein I” and “phaseolin”. This result supports the homologization between phaseolin and vicilin. Among the other proteins, three are irregularly distributed throughout the family, and only three are restricted to a few taxa. This last group includes phytohaemagglutinin, which does not present any cross reaction outside the tribePhaseoleae.

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The lengths of the A, B, and D genomes of common wheat,Triticum aestivum, were measured from the karyotype. Relative to the B genome, standardized as length 1.000, the lengths of the A and D genomes were 0.835 and 0.722, respectively. The lengths of the chromosome arms in the A and D genomes were then multiplied by the appropriate constants so that the total lengths of each genome also equalled 1.000. These calculations revealed that homoeologous chromosomes in wheat, with a few exceptions, have similar sizes and arm ratios. The arm lengths of the three homoeologues in each homoeologous group were then averaged. These average chromosomes turned out to be remarkably similar, in size and arm ratio, to their homoeologues in the E genome ofElytrigia elongata. This evidence and data on cross-compatibility and morphological characteristics suggested that the genusTriticum is a result of adaptive radiation from the perennial genusElytrigia, specifically from the complex of species possessing the E genome or one closely related to it.

    Keywords: Angiosperms ; Fabaceae ; Lupinus palaestinus ; L. pilosus ; Breeding system ; insect induced self pollination
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Significant increase of pod production occurs inLupinus palaestinus Boiss. andL. pilosus Murr. following insect visits. The cause of this increase is investigated through (1) examination of the biology of pollination, (2) examination of pod production under various pollination conditions, (3) examination of cross pollination by genetical markers. All data strongly suggest that “Insect Induced Self Pollination” is the main factor in the increase of pod production of these species in nature.

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The relationships of three wheat-Aegilops longissima chromosome addition lines A, C, and D with homoeologous wheat chromosomes were studied in PMC meiosis. Substitutions of alien chromosome A for wheat chromosome 6 B, chromosome C for 1 B and chromosome D for 4 B were obtained. The production of 4 BS/C and 7 BS/D chromosome translocations indicated cytogenetic relationships of C partially to homoeologous wheat chromosomes of group 1 and 4, and D partially to homoeologous wheat chromosomes of group 4 and 7.

    Notes: Abstract Samples from 11 populations of wild barley,Hordeum spontaneum, from Israel, were examined for morphological variation in a “common garden” plot design. Earliness traits had the highest between population variation of all traits studied. No relationship was found between dimensions of leaves and size of seeds.—Using numerical taxonomy methods, four races were found, which correspond to the geographical and environmental range of the species in Israel. It is concluded thatH. spontaneum shows a well developed tendency toward formation of highly adaptive races rather than exhibiting clinical variation.
