Molecular Confirmation that Sterile Cytoplasm Has Been Introduced into Open-pollinated Grano Onion Cultivars

Has Coxiella burnetii (Q fever) Been Introduced into New Zealand?

grade fever of 2 months' duration. His past medical history was unremark-able, except for pulmonary tuberculosis treated 55 years earlier and chronic glaucoma. He lived in a rural area and had rare contact with cattle. On admission , his body temperature was 39.5°C; his right laterocervical lymph nodes were enlarged (3 cm x 4 cm) and inflamed. Blood values were unre-markable except for an eleva...

Comparison of Open-pollinated and Hybrid Onion Varieties for New Mexico

Eighteen hybrid onion and 23 open-pollinated (OP) varieties were tested in southern New Mexico for plant characteristics, disease resistance, and bulb yield in order to determine if hybrid varieties outperformed OP varieties. Varieties were shortto intermediate-day in their bulbing response and were planted in the fall seasons of 1997 and 1998 and harvested the following May or June. Varieties ...

The use of cytoplasmic markers in onion hybrid breeding.

We applied the RFLP approach to identify the cytoplasmic genotypes of selected onion breeding materials from Poland. For this purpose, mitochondrial DNA from cytoplasmic male-sterile (CMS) and male-fertile onions were hybridized with the probes for the following mitochondrial genes: atpA, atp6, atp9, cob, cox1, nad3, nad4 and nad6. S-, T- or C-cytoplasm was represented in each analyzed sterile ...

The Americas region declares that rubella has been eliminated.

It has been conjectured that self-replicating systems will enab

It has been conjectured that self-replicating systems will enable complex macroscale objects to be made in a reasonable time using nanoscale assembly processes [1]. Self-replicating systems might also be used within reconfigurable structures on any scale, such as micro-circuits. An abstract model of a programmable constructor in a kinematic simulation environment is presented. This programmable...
