Studies on the interspecific crossing compatibility among three Prunus species and their hybrids

Budding Compatibility of Almond and Plum on Some Wild Species and Interspecific Hybrids of Almond

Cytogenetic 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...

Interspecific Hybrids

The regulation of gene expression is essential for organismal form, function, and fitness. Complex organismal development from zygote to adult requires finely tuned expression of genes in space, time, and abundance. Proper expression of genes is also required for most other aspects of physiology and function. Even minor changes in gene expression have the potential to significantly impact pheno...

The Cytogenetic Study of Crossing over in Interspecific Hybrids between DROSOPHILA VIRILIS and D. TEXANA.

Spontaneous crossing over was studied by means of combined cytological and genetic methods in F(1)Drosophila virilis x D. texana females (series I) and in D. virilis females carrying a D. texana fifth chromosome in heterozygous condition (series II). The main criterion utilized to distinguish the oogonial crossovers from the meiotic ones is the identity of cytological positions of genetic excha...

Gene regulatory divergence among species estimated by altered developmental patterns in interspecific hybrids.

Disturbances in the schedules of gene expression in developing interspecific fish hybrids have been used to draw inferences about the extent of gene regulatory divergence between species and about the degree to which this gene regulatory divergence is correlated with structural gene divergence, as estimated by genetic distance. Sperm from each of 10 different species representing six genera wit...
