Mitochondrial phylogeny and distribution of cytoplasmic male sterility-associated genes in Beta vulgaris.

Cytoplasmic male sterility (CMS) is a mitochondrial-encoded trait that confers reproductive defects in males but not in females or any vegetative function. Why CMS is so often found in plants should be investigated from the viewpoint of mitochondrial phylogeny. Beta vulgaris, including the wild subspecies maritima and cultivated subspecies vulgaris (e.

Selection of nuclear genotypes associated with the thermo-sensitivity of Owen-type cytoplasmic male sterility in sugar beet (Beta vulgaris L.).

Cytoplasmic male sterility in sugar beet becomes thermo-sensitive when combined with specific genotypes, potentially offering a means to environmentally control pollination by this trait. The stability of cytoplasmic male sterility expression in several genetic backgrounds was investigated in sugar beet (Beta vulgaris L.).

Vasa praevia with meandering fetal vessels despite placental and umbilical cord insertion on the same side of the uterine wall: A case report.

Vasa praevia with meandering fetal vessels is extremely rare, and it is difficult to diagnose this prenatally. When cesarean section is performed, a change in the site of uterine incision may be required for a safe delivery.

The molecular basis for allelic differences suggests Restorer-of-fertility 1 is a complex locus in sugar beet (Beta vulgaris L.).

Background: Cytoplasmic male sterility (CMS) is a widely used trait for hybrid seed production in many crops. Sugar beet CMS is associated with a unique mitochondrial protein named preSATP6 that forms a 250-kDa complex. Restorer-of-fertility 1 (Rf1) is a nuclear gene that suppresses CMS and is, hence, one of the targets of sugar beet breeding.

How did a duplicated gene copy evolve into a gene in a plant? The case of .

() is a suppressor of cytoplasmic male sterility (CMS), a mitochondrion-encoded trait that has been reported in many plant species. The occurrence of CMS is considered to be independent in each lineage; hence, the question of how evolved was raised. Sugar beet resembles , a gene for quality control of the mitochondrial inner membrane.

Radiotherapy for Erdheim-Chester disease.

A 42-year-old woman suffered from pain in both legs, and fever. She was diagnosed with Erdheim-Chester disease (ECD), based upon bone biopsy. Initially, she received steroid therapy, which led to temporary improvement.
