Hybridization Assays

A new seedborne strain of cucumber mosaic cucumovirus (CMV) that induces severe symptoms on many cowpea genotypes was detected in Georgia in 1994. This strain, designated CMV-Csb, is asymptomatic on tobacco, but it produces more severe cowpea stunt symptoms when present in combination with blackeye cowpea mosaic potyvirus than do the more prevalent CMV isolates. The new strain is seedborne in cowpea (1.5 to 37%), has no associated satellite RNA, and is classified as a member of subgroup I of CMV strains based on nucleic acid hybridization assays.

Hinge Domain

Structural maintenance of chromosomes flexible hinge domain containing 1 (SMCHD1) is an epigenetic regulator in which polymorphisms cause the human developmental disorder, Bosma arhinia micropthalmia syndrome, and the degenerative disease, facioscapulohumeral muscular dystrophy. SMCHD1 is considered a noncanonical SMC family member because its hinge domain is C-terminal, because it homodimerizes rather than heterodimerizes, and because SMCHD1 contains a GHKL-type, rather than an ABC-type ATPase domain at its N terminus. The hinge domain has been previously implicated in chromatin association; however, the underlying mechanism involved and the basis for SMCHD1 homodimerization are unclear. Here, we used x-ray crystallography to solve the three-dimensional structure of the Smchd1 hinge domain. Together with structure-guided mutagenesis, we defined structural features of the hinge domain that participated in homodimerization and nucleic acid binding, and we identified a functional hotspot required for chromatin localization in cells. This structure provides a template for interpreting the mechanism by which patient polymorphisms within the SMCHD1 hinge domain could compromise function and lead to facioscapulohumeral muscular dystrophy.

Todd has made highly significant contributions to the chemistry of natural products, in particular in relation to compounds which play important roles in biological systems. His researches on vitamins B 1 , E and B 12 were most elegant and have had far-reaching implications, but none more so than his structural and synthetic studies in the nucleic acid field. Here he developed methods for the synthesis of the nucleosides and for their phosphorylation; his work on the way they are combined made possible the subsequent determination of the three-dimensional structure of the nucleic acids thereby providing the basis for much of the exciting activity in the nucleotide field today. Todd’s achievements arise out of a rare combination of theoretical knowledge and outstanding experimental skill, with the most judicious exploitation of modern techniques. His work and his quality as an investigator have been widely recognized by biologists as well as by organic chemists.
