Cytogenetic Notes on Tomato Species and Hybrids.
Since Lycopersicon was separated from the closely related Solanum, the species of tomatoes have been reduced by taxonomic revisions to six (MULLER 1940) or seven (LUCKWILL 1g43), all probably indigenous to the West coast of South America or the adjacent Galapagos Islands. These species are naturally divided into two sections or subgenera: I. EULYCOPERSICON, containing the two edible and widely ...
متن کاملMorphological and molecular identification to secure cultivar maintenance and management of self-sterile Rubus arcticus.
BACKGROUND AND AIMS Preservation of cultivar purity creates a particular challenge for plants that are self-incompatible, require insects for cross-pollination, and have easily germinating seeds and vigorously spreading rhizomes. As the fields must be planted with mixed populations, and a balance must be maintained between the cultivars to achieve effective pollination, methods for field monito...
متن کاملImpact of cytogenetic and molecular cytogenetic studies on hematologic malignancies.
Conventional cytogenetic analysis of chromosome abnormalities in hematologic malignancies is hampered by the low mitotic index and poor quality of metaphases. A range of techniques based on fluorescence in situ hybridization (FISH) has greatly enhanced the identification of non-random translocations and deletions, pinpointing regions which contain genes involved in leukemogenesis. One of the ma...
متن کاملCytogenetic Studies in Paeonia II. the Cytology of the Diploid Species and Hybrids.
H E cytological study of the numerous species and hybrids in the T SAUNDERS collection has now been carried on intermittently for five years, during which time a considerable amount of data have been accumulated. The present paper aims to present the most significant findings in the diploid species and hybrids, particularly insofar as they help to explain species relationships in this most comp...
متن کاملCytogenetic Studies in Paeonia I. the Compatibility of the Species and the Appearance of the Hybrids.
INCE 1916, the senior author has carried on an extensive series of S crossing experiments in the genus Paeonia, with the object both of obtaining new horticultural forms and of securing evidence concerning the interrelationships of the species and the processes of evolution within the genus. Some accounts of the hybrids have already been published (SAUNDERS 1928, 1933a, 193313). The junior auth...
