for five years in deliberations and correspondence with Cactaceae specialists of the …

Convergence of genes and cellular pathways dysregulated in autism spectrum disorders

…, S Thomson, L Soorya, B Rogé, W Roberts… - The American Journal of …, 2014 - cell.com
Rare copy-number variation (CNV) is an important source of risk for autism spectrum
disorders (ASDs). We analyzed 2,446 ASD-affected families and confirmed an excess of genic …

Phylogenetic studies of Mammillaria (Cactaceae)—insights from chloroplast sequence variation and hypothesis testing using the parametric bootstrap

CA Butterworth, RS Wallace - American Journal of Botany, 2004 - Wiley Online Library
The genus Mammillaria is likely the most species‐rich and morphologically variable genus
in the Cactaceae. There is doubt as to whether the genus is monophyletic, and past …

Phylogeny of the portulacaceous cohort based on ndhF sequence data

WL Applequist, RS Wallace - Systematic Botany, 2001 - BioOne
The Portulacaceae, Basellaceae, Cactaceae, and Didiereaceae form a monophyletic group
within the Caryophyllales, and evidence exists that the first may be paraphyletic if the latter …

A genome-wide scan for common alleles affecting risk for autism

…, JB Vincent, F Volkmar, S Wallace… - Human molecular …, 2010 - academic.oup.com
Although autism spectrum disorders (ASDs) have a substantial genetic basis, most of the
known genetic risk has been traced to rare variants, principally copy number variants (CNVs). …

Molecular systematic study of the Cactaceae: using chloroplast DNA variation to elucidate cactus phylogeny

RS Wallace - Bradleya, 1995 - BioOne
: Studies of molecular variation within the chloroplast genome have been used to determine
phylogenetic relationships within the evolutionarily complex family Cactaceae. Changes …

KJ Kim, RK Jansen, RS Wallace, HJ Michaels… - Annals of the Missouri …, 1992 - JSTOR
Complete nucleotide sequences of the rbcL gene were obtained for 25 species of Asteraceae
representing 15 of the currently recognized tribes and three outgroup families. A total of …

Molecular systematics of tribe Cacteae (Cactaceae: Cactoideae): a phylogeny based on rpl16 intron sequence variation

CA Butterworth, JH Cota-Sanchez, RS Wallace - Systematic Botany, 2002 - BioOne
Parsimony analysis of plastid rpl16 sequences from 62 members of Tribe Cacteae, and four
outgroup taxa yielded 1296 equally parsimonious trees of length 666. Strict consensus …
