    Notes: Abstract In the progeny after selfing of a normally open pollinated variety (L.S. 326-3) of pearl millet (Pennisetum americanum (L.) Leeke, n=7) one plant exhibited desynapsis, chromosome stickiness and high sterility. Meiosis was normal until diplotene. Thereafter, it was characterized by dissociation of bivalents into univalents and formation of nonspecific congregations of chromosomes at diakinesis, shrinkage of cytoplasm and occurrence of unoriented sticky chromatin masses at metaphase I, relaxation of stickiness, unbalanced chromosome numbers at the poles and laggards at anaphase I, and presence of other irregularities in subsequent stages. Meiosis was completed. Male and female sterility was high. This meiotic mutant thus has multiple effects and is inherited as a monogenic recessive and designated as st.

    Notes: Summary The mammalian centrosome monoclonal antibody MPM-13 recognized component(s) of the well defined MTOC basal-body root complex in the green plantChlamydomonas. The antibody reaction coincided in location with the basal-body root complex and the cruciate nature of the staining pattern corresponded to the configuration of the root microtubules. During mitosis the behaviour of MPM-13 stained material mirrored the duplication, separation and migration to the spindle poles of the basal body-root complex. It is suggested that conserved MTOC components were recognized and that these may have retained a similar, perhaps universal, function in microtubule organization.
