(16) Upon mutation of the gene, petals are transformed to sepals and stamens to carpels, indicating that deficiens is essential for the activation of genes required for petal and stamen formation.
(17) Transcripts are present in petals, stamens and pistil but are not detectable in sepals.
(18) However, PR-2 polypeptides were observed only in sepal tissue.
(19) AP2 is a floral homeotic gene that is necessary for the normal development of sepals and petals in floral whorls 1 and 2.
(20) The fbp2 gene is expressed in petals, stamen, carpels, and at a very low level in sepals but not in vegetative tissues.
Septal
Definition:
(a.) Of or pertaining to a septum or septa, as of a coral or a shell.
Example Sentences:

(3) A block of tissue bounded by the ostium of the coronary sinus, the pars membranacea, the septal leaflet of the tricuspid valve and the atrial and ventricular septa is removed.
(4) The type I cells are squamous and give off attenuated sheets of cytoplasm which spread widely over the septal surface; these sheets contain few organelles.
(5) The hemodynamic measurements and mitral valve area calculations were performed with and without balloon occlusion of the atrial septal puncture site.
(6) To evaluate interatrial septal motion throughout the cardiac cycle, echocardiograms of the septum were obtained by esophageal echocardiography simultaneously with left and right atrial pressures using Millar's micromanometers in nine subjects with sinus rhythm.
(7) We have examined the distribution of galanin-like immunoreactive (LI) cell bodies in the medial septal nucleus (MS) and the nucleus of the diagonal band of Broca (nDBB) of young (3 months) and aged (25-30 months) rats, and assessed their respective contribution to the septohippocampal pathway.
(8) Two experiments reported the effects of prefeeding normal and septal rats prior to their daily sessions on a differential reinforcement of low rates (DRL-20) schedule.
(9) These factors include narrowing of septal arteries and the artery to the atrioventricular node, preservation of fetal anatomy with dispersion in the atrioventricular node and His bundle, fibrosis of the sinus node, clefts in the septum, multiple atrioventricular pathways and massive myocardial infarction.
(10) The hippocampal projection to Rgb originates in area CA1, dorsal (septal) subiculum, and post-subiculum.
(11) Branches of the anterior and middle cerebral arteries and thalamostriate, septal, and internal cerebral veins can be clearly defined with computed tomography during contrast enhancement with the Ohio Nuclear Delta 25 scanner.
(12) The diagnosis was considered established, when the patient had a significant left intraventricular pressure gradient (LIPG) and by angiographic and or echocardiographic demonstration of systolic anterior movement of the mitral valve and asymmetric septal hypertrophy.
