  • A Linkage between Purple Flower and White Flower in Pharbitis Nil

    1. The linkage relation of contracted (ct) to white-2 (a2) was studied in both cases of coupling and repulsion. The frequency of recombination was 44.0 percent in coupling, 39.5 percent in repulsion.
    2. A high linkage was found between a2 and purple (pr), though the frequency of recombinations was impossible to calculate on the segregation in F2. This fact demonstrates pr to be a member of the contracted linkage group.
    3. The occurrence of a close linkage between a2 and i1 was respectively observed in both cases of coupling and repulsion.
    4. Dragonfly-1 (dg1) for dragonfly leaf links to a2, the frequency of recombinations being 23.0 percent.
    5. Faint coloured flower-tube are brought about by either one of two genes, termed faintish (ft) and extended (e) respectively. The former, faintish belongs to the contracted linkage group, being linked with dg1, and with 10.5 percent recombination. The latter, extended links to dragonfly-2 (dg2) of the duplicated linkage group, the frequency of recombinations being 27.1 percent.
    6. Depending upon the linkage studies, the following conclusion may be given here. Five genes, newly adding faintish (ft) and purple (pr) to three genes-intense-1, white-2, dragonfly-1, belong to the contracted linkage group, and have each loci on the right region of the contracted chromosome, the order of arrangement being probably i1-a2-pr-ft-dg1.

  • On the Systematic Anatomy of the Leaves of Some Japanese Carices. XXII

    1. Anatomical characteristics of the leaves of Carex tristachya, C. oshimensis and C. okushirensis are described in this paper; the remarkable points of the characteristics are as below:-
    Carex tristachya THUNB.: Upper epidermal cells have extremely wavy cell-walls. Spine cells occur in the upper epidermis, the margins and the under epidermis on the midrib. Protuberances exist in the upper epidermis and the under epidermis on the midrib. Neighbouring two vacuoles often connect at the under side of the smaller vascular bundle.
    Carex oshimensis NAKAI: All epidermal cells are conspicuously wavy. Spine cells occur in the upper epidermis (near the sides of hinge cells), the margins and the under epidermis on the midrib. Hinge cells are in two or more layers, presenting flattened outer appearances. Large and small vascular bundles occur alternately.
    Carex okushirensis AKIYAMA: Upper and under epidermis are conspicuously wavy. Spine cells are in two layers, showing flattened outer appearances. Large and small vascular bundles occur alternately.
    2. C. oshimensis resembles C. Morrowii or C. foliosissima, and C. okushirensis resembles C. conica, but these can be distinguished by the forms of the hinge cells, the types of the arrangement of the vascular bundles and the existence or the absence of stomata in the upper epidermis near the margins.

    On the Behaviour of Nucleolus in the Meiosis of the Pollen Mother Cell

    The behaviour of nucleolus, especially its relation to chromosomes is followed in the materials stained with iron alum and vanadium haematoxylin and FEULGEN'S fuchsin-Sulphurous acid with or without counterstaining with light green. According to the staining reactions both chromosomes and nucleoli contain at least two sorts of substances, one being nucleal-positive and the other nucleal-negative, but stainable with both vanadium haematoxylin and light green. With iron haematoxylin we can not distinguish these two components of karyoplasm, because it stains both of them. In chromosomes these two components correspond respectively to karyotin proper (chromonemata) and matrix (hyalonemata), while the main nucleolar substance (plastin) is nucleal-negative and the nucleal-positive component is distributed in the periphery of nucleolinus (nucleolar vacuole). Throughout the whole cycle of meiosis certain chromosomes are found to be connected with a nucleolus in two ways: (1) the end of a spireme or chromosome is attached to the surface of a nucleolus. (2) the centre of a nucleolus (nucleolinus) communicates with the end of a chromosomes with a fine thread, which simulates a trabant chromosome. The nucleolus appears to supply chromosomes with nucleal-negative component of karyoplasm in the course of prophases of meiosis.

  • On the Spore Formation within the Culture Solution in Some Aspergilli

    1. In Aspergillus flavus and Asp. tamari spore formation occurs within the culture solution, if the amount of glucose, given as the carbon source, is reduced or any one of the nitrogen, phosphor and sulphur source is eliminated. The same thing is visible in Asp. oryzae, only when the amount of glucose is reduced.
    2. The elimination neither of potassium nor magnesium has to do with the spore formation within the culture solution.
    3. The state of the developed submerged spore corresponds to that of the unripe aerial conidium. The formation of the typical verrucrose surface, which is proper for these fungi, can not be completed in the ease of the submerged spore.
    4. Heavy metals iron, zinc, copper and manganese have not to do directly with the formation of the submerged spore, but a relatively high concentration of copper hinders it, especially when manganese is omitted.
    5. Either too high or too low hydrogen ion concentration is unfavourable for the formation of the submerged spore.
    6. In Asp. tamari it is often observed that spore are formed within the submerged as well as aerial mycelium. The endospore of the type is to be regarded as a modified form of the ordinary spore and no special meaning may be attributed to it.
