A contradictory GLABRA3 allele helps define gene interactions controlling trichome development in Arabidopsis.
Previously characterized Arabidopsis gl3 mutants have trichomes that are smaller, less branched and undergo fewer rounds of endoreplication than wild-type trichomes. A new gl3 mutant, called gl3-sst, has oddly shaped trichomes that over expand during early development, undergo more endoreduplication and that have a striking nuclear morphology. The mutant nuclei consist of many interconnected lo...
متن کاملAn overview of the gene regulatory network controlling trichome development in the model plant, Arabidopsis
Trichomes are specialized epidermal cells located on aerial parts of plants and are associated with a wide array of biological processes. Trichomes protect plants from adverse conditions including UV light and herbivore attack and are also an important source of a number of phytochemicals. The simple unicellular trichomes of Arabidopsis serve as an excellent model to study molecular mechanism o...
متن کاملFine mapping and candidate gene analysis of Brtri1, a gene controlling trichome development in Chinese cabbage (Brassica rapa L. ssp pekinensis).
Trichomes are derived from the epidermis and constitute an ideal system for studying cell division in plants. Here, a Chinese cabbage doubled haploid (DH) line (FT) without trichomes was crossed with another DH line (PurDH-1) with trichomes to develop an F2 population for fine mapping of trichome control genes. Genetic analysis showed that the trichome phenotype was controlled by a single domin...
متن کاملVirus-Host Gene Interactions Define HIV-1 Disease Progression.
In this chapter, we will review recent research on the virology of HIV-1 transmission and the impact of the transmitted virus genotype on subsequent disease progression. In most instances of HIV-1 sexual transmission, a single genetic variant, or a very limited number of variants from the diverse viral quasi-species present in the transmitting partner establishes systemic infection. Transmissio...
متن کاملLymphatic mapping helps to define resection margins for midgut carcinoids.
BACKGROUND The extensive mesenteric lymphadenopathy associated with midgut carcinoids often causes lymphatic obstruction and leads to the development of alternative lymphatic drainage pathways. We hypothesized that altered lymphatic drainage makes traditional determination of resection margins inadequate. METHODS One hundred and seventy patients underwent cytoreductive surgery for neuroendocr...
