Two Oppositely Localised Frizzled RNAs as Axis Determinants in a Cnidarian Embryo
In phylogenetically diverse animals, including the basally diverging cnidarians, "determinants" localised within the egg are responsible for directing development of the embryonic body plan. Many such determinants are known to regulate the Wnt signalling pathway, leading to regionalised stabilisation of the transcriptional coregulator beta-catenin; however, the only strong molecular candidate f...
متن کاملA maternally localised Wnt ligand required for axial patterning in the cnidarian Clytia hemisphaerica.
Regionalised activation of canonical Wnt signalling via beta-catenin stabilisation is a key early step in embryonic patterning in many metazoans, including the basally diverging cnidarians, but the upstream maternal cues appear surprisingly variable. In Clytia, regionalised beta-catenin stabilisation defining a presumptive 'oral' territory is determined by two maternally coded Frizzled family W...
متن کاملAxis Patterning by BMPs: Cnidarian Network Reveals Evolutionary Constraints
BMP signaling plays a crucial role in the establishment of the dorso-ventral body axis in bilaterally symmetric animals. However, the topologies of the bone morphogenetic protein (BMP) signaling networks vary drastically in different animal groups, raising questions about the evolutionary constraints and evolvability of BMP signaling systems. Using loss-of-function analysis and mathematical mod...
متن کاملSepah (Shohada), a historical avenue, as a joint axis in city of Qazvin’s Integration theory
Shohada (Sepah) avenue in Qazvin, a historic city, is a part of Safavid era infrastructure of the city. It connects various important cites and poles like Jame' mosque, Imamzadeh Hosein, Dowlat-Khaneh and the Traditional Bazaar complex to one another. This axis in KhomarTashi, in Kabir Jame' mosque - preservation and restoration of Jame' mosque complex as principle core of the city which is ...
متن کاملTwo small regulatory RNAs establish opposing fates of a developmental axis.
Small RNAs are important regulators of gene expression. In maize, adaxial/abaxial (dorsoventral) leaf polarity is established by an abaxial gradient of microRNA166 (miR166), which spatially restricts the expression domain of class III homeodomain leucine zipper (HD-ZIPIII) transcription factors that specify adaxial/upper fate. Here, we show that leafbladeless1 encodes a key component in the tra...
