NUBBIN and JAGGED define stamen and carpel shape in Arabidopsis.
Differential growth of tissues during lateral organ development is essential for producing variation in shape and size. Previous studies have identified JAGGED (JAG), a gene that encodes a putative C2H2 zinc-finger transcription factor, as a key regulator of shape that promotes growth in lateral organs. Although JAG expression is detected in all floral organs, loss-of-function jag alleles have ...
متن کاملHUA1, a regulator of stamen and carpel identities in Arabidopsis, codes for a nuclear RNA binding protein.
Stamen and carpel identities are specified by the combinatorial activities of several floral homeotic genes, APETALA3, PISTILLATA, AGAMOUS (AG), SEPALLATA1 (SEP1), SEPALLATA2 (SEP2), and SEPALLATA3 (SEP3), all of which code for MADS domain DNA binding proteins. AG and the SEP genes also control floral determinacy. HUA1 and HUA2 were identified previously as regulators of stamen and carpel ident...
متن کاملJAGGED Controls Arabidopsis Petal Growth and Shape by Interacting with a Divergent Polarity Field
A flowering plant generates many different organs such as leaves, petals, and stamens, each with a particular function and shape. These types of organ are thought to represent variations on a common underlying developmental program. However, it is unclear how this program is modulated under different selective constraints to generate the diversity of forms observed. Here we address this problem...
متن کاملmanipulation in dubbing and subtitling
پژوهش حاضر در چارچوب مکتب دستکاری قرار گرفت و با استفاده از تقسیم بندی دوکات (2007) از شیوه های دستکاری، به دنبال یافتن پاسخ برای پرسش های زیر بود: 1-رایج ترین شیوه دستکاری در دوبله فیلم ها کدام است؟ 2-رایج ترین شیوه دستکاری در زیرنویس فیلم ها کدام است؟ 3-دستکاری در دوبله فیلم ها رایج تر است یا در زیرنویس آن ها؟ این پژوهش از نوع تحقیقات توصیفی- مقایسه ای و پیکره ای می باشد. پیکره تحقیق شا...
Detecting low shape-frequencies in smooth and jagged contours
It is often assumed that a two-stage filter-process is involved in the coding of visual contours. In the first stage the contour is coded by localized luminance filters selective for, among other dimensions, orientation and spatial frequency. A second stage then integrates the outputs of these local luminance filters over space. In the experiments described here we address the issue of which sp...
