Branch geometry in Cornus kousa (Cornaceae): computer simulations.
Computer simulations similar to actual trees were constructed using simple branching rules. Branch orientation with respect to the direction of gravity was a fundamental consideration. In Cornus kousa BUERG. ex HANCE, several types of branches develop from winter buds, varying from orthotropic shoots to plagiotropic ones. Based on actual observations and measurements of branching structures wit...
متن کاملTransfer of Cornus florida and C. kousa Simple Sequence Repeats to Selected Cornus (Cornaceae) Species
ABSTRACT. Cross-species transferability of simple sequence repeats (SSRs) is common and allows SSRs isolated from one species to be applied to closely related species, increasing the use of previously isolated SSRs. The genus Cornus consists of 58 species that are ecologically and economically important. SSRs have previously been isolated from C. florida and C. kousa. In this study, 36 SSRs wer...
متن کاملMicrosatellites from kousa dogwood (Cornus kousa).
Microsatellite loci were identified from Cornus kousa'National'. Primer pairs for 86 loci were developed and of these, eight were optimized and screened using genomic DNA from 22 kousa cultivars. All optimized loci were polymorphic and the number of alleles per locus ranged from three to 17. Observed heterozygosity ranged from 0 to 0.3 and expected heterozygosity ranged from 0.38 to 0.91. These...
متن کاملPhylogenetic relationships within Cornus (Cornaceae) based on 26S rDNA sequences.
Phylogenetic relationships within the dogwood genus Cornus have been highly controversial due to the great morphological heterogeneity. Earlier phylogenetic analyses of Cornus using chloroplast DNA (cpDNA) data (including rbcL and matK sequences, as well as restriction sites) and morphological characters suggested incongruent relationships within the genus. The present study generated sequence ...
متن کاملCornus × elwinortonii and Cornus × rutgersensis (Cornaceae), new names for two artificially produced hybrids of big-bracted dogwoods
Big-bracted dogwoods (Cornus sp.) are well-known plants in North America and eastern Asia where they occur as wild, generally spring-flowering understory trees. They are also popular ornamental landscape plants, and many economically important cultivars are propagated and sold across North America, Europe, and Asia. Starting in the late 1960s, Elwin Orton of Rutgers University in New Jersey (US...
