Methyl -{(1)-2-[(meth-oxy-carbon-yl)-oxy]-1-phenyleth-yl}carbamate.

The title mol-ecule, CHNO, is a methyl carbamate derivative obtained by reacting ()-2-phenyl-glycinol and methyl chloro-formate, with calcium hydroxide as heterogeneous catalyst. Supra-molecular chains are formed in the [100] direction, based on N-H⋯O hydrogen bonds between the amide and carboxyl-ate groups. These chains weakly inter-act in the crystal, and the phenyl rings do not display significant π-π inter-actions.

Accumulation and Transmission of ' Liberibacter solanacearum' Haplotypes by the Nymphs of Two Psyllid Vectors.

' Liberibacter solanacearum' (Lso) is a plant pathogenic bacterium transmitted by psyllids that causes significant agricultural damage. Several Lso haplotypes have been reported. Among them, LsoA and LsoB are transmitted by the potato psyllid and infect solanaceous crops, and LsoD is transmitted by the carrot psyllid and infects apiaceous crops.

'Jones hybrid' hickory: a case study in curation.

'Jones Hybrid' hickory is an accession in the National Collection of Genetic Resources for Pecans and Hickories for which information about origin, identity and characteristics is very incomplete. Phenotypic and genetic profiles, when examined in the context of historic literature, provide evidence that the accession in question is 'Siers' a cultivar of  ×  (an interspecific hybrid between and ). The accession has traits that make it interesting in the pecan breeding program, with potential for both rootstock and scion development.
