    Notes: Abstract Before somatic embryogenesis can be applied, the genetic fidelity of cultures needs to be determined. Problematic of tissue-cultured woody species is the extensive evaluation time needed for assessments. The development of methods whereby plants could be rapidly screened for potential tissue culture-derived genetic changes would be very valuable. We evaluated the applicability of AFLP (amplified fragment length polymorphism) analysis for the assessment of genetic variability in somatic embryos of pecan [Carya illinoinensis (Wangenh.) C. Koch] and made comparisons between and within embryogenic culture lines. AFLP readily detected differences between culture lines, with 368 polymorphic loci identified. Individual culture lines generally produced somatic embryos with similar overall banding patterns. Embryos derived from the same culture line generally grouped together in a phenogram generated by UPGMA (unweighted pair-group method, arithmetic average) analysis. However, a few somatic embryos exhibited higher levels of polymorphism and failed to group with others regenerated from the same line. The relation between the detected within-line differences and their contribution to phenotypic variation is yet to be determined.

    Notes: Summary Somatic cells of mature asexual colonies of Volvox carteri do not possess a true cell wall, but are otherwise similar in ultrastructure to Chlamydomonas. Somatic cells are embedded in multilayered fibrillar material of the colonial matrix. The reproductive cells (gonidia) of Volvox carteri lie internal to the somatic cell layer of the colony matrix in an apparently structureless portion of the colony matrix. Mature gonidia are large vacuolate cells with a central nucleus and parietal chloroplasts and mitochondria. They are non-flagellated at maturity, but each contains a pair of kinetosomes.

    Notes: Summary The similarity in structure of the flagellum, star body, kinetosome, proximal and distal kinetosome bridges, and the girdling bands of microtubules in the somatic cells of Volvox carteri and the vegetative cells of Chlamydomonas suggests, on an ultrastructural basis, the interrelated nature of Volvox and Chlamydomonas.

    Notes: Abstract  Cultivated alfalfa (Medicago sativa) is an autotetraploid. However, all three existing alfalfa genetic maps resulted from crosses of diploid alfalfa. The current study was undertaken to evaluate the use of Simple Sequence Repeat (SSR) DNA markers for mapping in diploid and tetraploid alfalfa. Ten SSR markers were incorporated into an existing F2 diploid alfalfa RFLP map and also mapped in an F2 tetraploid population. The tetraploid population had two to four alleles in each of the loci examined. The segregation of these alleles in the tetraploid mapping population generally was clear and easy to interpret. Because of the complexity of tetrasomic linkage analysis and a lack of computer software to accommodate it, linkage relationships at the tetraploid level were determined using a single-dose allele (SDA) analysis, where the presence or absence of each allele was scored independently of the other alleles at the same locus. The SDA diploid map was also constructed to compare mapping using SDA to the standard co-dominant method. Linkage groups were generally conserved among the tetraploid and the two diploid linkage maps, except for segments where severe segregation distortion was present. Segregation distortion, which was present in both tetraploid and diploid populations, probably resulted from inbreeding depression. The ease of analysis together with the abundance of SSR loci in the alfalfa genome indicated that SSR markers should be a useful tool for mapping tetraploid alfalfa.
