A functional cellulose synthase from ascidian epidermis.
Among animals, urochordates (e.g., ascidians) are unique in their ability to biosynthesize cellulose. In ascidians cellulose is synthesized in the epidermis and incorporated into a protective coat know as the tunic. A putative cellulose synthase-like gene was first identified in the genome sequences of the ascidian Ciona intestinalis. We describe here a cellulose synthase gene from the ascidian...

متن کاملChromosome mosaicism in a hermaphrodite.
The chromosome complement in 27 patients with convincing evidence of hermaphroditism has now been investigated. A normal female karyotype (44 autosomes + XX) was reported in I7 cases (Bregman, Bregman, Cushner, and Woods, I963; de Assis, Epps, and Bottura, I960; Dewhurst, Warrack, and Casey, I963; German, Bearn, and McGovern, I962; Gordon, O'Gorman, Dewhurst, and Blank, I960; Harnden and Armstr...
متن کاملTrue Hermaphrodite: A Case Report
True hermaphrodite is one of the rarest variety of disorders of sexual differentiation (DSD) and represents only 5% cases of all. A 3-year-old child presented with left sided undescended testis and penoscrotal hypospadias. Chordee correction was performed 18 months back, elsewhere. At laparotomy Mullerian structures were present on left side. On right side testis was normally descended into the...
متن کاملHermaphrodite with Mosaic
SIR,-In a recent review de Grouchy 1 compiles the following karyotypes described in true hermaphroditism: 46 XX, 46 XY, 46 XX/46 XY, 45 XO/46 XY, 46 XX/47 XXY, 46 XX/47 XXX, 46 XX/46 XY/45 XO, 46 XX/47 XXY/ 49 XXYYY, and 45 XO/46 X isoY/47 XY isoY. We have studied the chromosomes of a true hermaphrodite with a new mosaicism, 46 XX/46 XY/47 XXY, which might throw some light on the possible multi...
