    Notes: Abstract  We present the first genetic map of wild rice (Zizania palustris L., 2n=2x=30), a native aquatic grain of northern North America. The map is composed principally of previously mapped RFLP (restriction fragment length polymorphism) genetic markers from rice (Oryza sativa 2n=2x=24). The map is important as a foundation for genetic and crop improvement studies, as well as a reference for genome organization comparisons among Gramineae species. A comparative mapping approach with rice is especially useful because wild rice is grouped in the same subfamily, Oryzoideae, and no other mapping comparison has yet been made within the subfamily. As rice is the reference point for mapping and gene cloning in cereals, establishing a consensus map within the subfamily identifies conserved and unique regions. The genomes of wild rice and rice differ in total DNA content (wild rice has twice that of rice) and chromosome pairs (wild rice=15 versus rice=12). The wild rice linkage map reported herein consists of 121 RFLP markers on 16 linkage groups spanning 1805 cM. Two linkage groups consist of only two markers. Colinear markers were found representing all rice linkage groups except #12. The majority of rice loci mapped to colinearly arranged arrays in wild rice (92 of 118). Features of the map include duplication of portions of three rice linkage groups and three possible translocations. The map gives basic information on the composition of the wild rice genome and provides tools to assist in the domestication of this important food source.

    Light and electron microscopic cytochemistry of the epidermal mucoid cells ofAeolidia papillosa andCoryphella rufibranchialis (Mollusca, Nudibranchia) (1983)

    Notes: Summary The epidermal mucoid cells in the cerata ofAeolidia papillosa andCoryphella rufibranchialis were cytochemically tested to determine the composition of their secretory products. The PAS, alcian blue, PA-TSC-SP and high iron diamine stains were used to determine the presence of acidic, sulphated, and periodate-reactive groups on the mucopolysaccharides. The secretory granules in mucoid cells ofA. papillosa consisted of periodate-reactive mucopolysaccharides with acid groups other than sulphates. Each granule also contained fibrils which were not oxidized by periodic acid. The mucoid secretory granules inC. rufibranchialis contained weakly acidic sulphated mucopolysaccharides, but no periodate-reactive polysaccharide groups. In both aeolid nudibranchs the Golgi apparatus at the base of the mucoid cells contained products which stained the same as those in the secretory granules, confirming that the Golgi apparatus is involved in the synthesis of mucoid secretory products. In addition the mucoid cell Golgi complex ofC. rufibranchialis also gave rise to ellipsoid vacuoles which contained sulphated mucopolysaccharides.

    The Golgi apparatus in epidermal mucoid and ellipsoid-vacuolate cells ofAeolidia papillosa andCoryphella rufibranchialis (Nudibranchia) (1980)

    Notes: Summary The epidermal cell layer of the apical end of the ceras was investigated in two species of aeolid nudibranchs. Based on cellular inclusions, mostly two cell types were found: mucoid and ellipsoid-vacuolate cells. Mucoid cells ofCoryphella rufibranchialis have large heterogeneous and fibrillar secretory granules whereas inAeolidia papillosa, the granules are homogeneous, but vary in electron density from one cell to another. Ellipsoid-vacuolate cells contained large quantities of small vacuoles with an included ellipsoidal structure. Both species contained very numerous ellipsoid-vacuolate cells. Secretory granules and ellipsoid-vacuoles appear to arise from the Golgi apparatus and these contents stain with PAS, suggesting a polysaccharide composition. Mucoid cells contained both secretory granules and ellipsoid-vacuoles which may arise from the same Golgi apparatus.
