Ettin expression in gynoecium

WebApr 8, 2024 · Recently, we uncovered a non-canonical signalling mechanism for the plant hormone auxin whereby auxin directly affects the activity of the atypical auxin response factor (ARF), ETTIN towards... WebFurther, we have shown that disruptions to gynoecial pattern formation seen in ettin mutants can largely be attributed to ectopic SPATULA action. ETTIN's role seems to be to negatively regulate SPATULA expression in abaxial regions of the developing gynoecium.

WebATS and ETT were found to share an overlapping expression pattern during Arabidopsis ovule development and loss of either gene resulted in congenital fusion of the integuments and altered seed morphology. Webettin (ett) mutations have pleiotropic effects on Arabidopsis flower development, causing increases in perianth organ number, decreases in stamen number and anther formation, and apical-basal patterning defects in the gynoecium. The ETTIN gene encodes a protein with homology to DNA binding proteins which bind to auxin response elements. black printed jumpsuit with tshirt underneath https://mallorcagarage.com

WebFeb 16, 2024 · Besides, the expression level of OsMADS13 is increased and more widely detectable in the gynoecium of fon4-2 mutant (Xu et al., 2024). Thus, FON4 may function to repress OsMADS13 expression in the innermost whorl, or the increased expression of OsMADS13 may act as a molecular response to alleviate the expansion of the meristem … WebThe gynoecium arises from the center of the floral meristem (flower stage 6, as defined by Smyth et al., 1990) and forms a cylinder-like structure. At stage 9, four distinct tissue types can be recognized on the surface of the gynoecium, namely the apical stigma, the style, the carpel valves and the narrow stretch of epidermis covering the ...
