Imprinting in arabidopsis plants
Witryna5 gru 2013 · The study of imprinting events in plant embryos is complicated by their location deep in maternal tissue in close association with the endosperm and other tissues. This is particularly the case for Arabidopsis, where the embryo and its progenitor cells are extremely small. Witryna11 kwi 2024 · Wie Pflanzen sich an Hitzestress „erinnern“ und Toleranz entwickeln. Angesichts des Klimawandels, der die Kulturpflanzen weltweit immer mehr stresst, erforschte CHROMADAPT jene molekularen Mechanismen, welche den Pflanzen bei der Entwicklung von Hitzetoleranz helfen, wobei sich potenzielle Lösungen für die Agrar- …

Witryna14 cze 2024 · Sesquiterpenes are important defense and signal molecules for plants to adapt to the environment, cope with stress, and communicate with the outside world, and their evolutionary history is closely related to physiological functions. In this study, the information of plant sesquiterpene synthases (STSs) with identified functions were … Witryna21 cze 2024 · Here, we employ single-nucleus RNA-sequencing to generate a transcriptional atlas of developing Arabidopsis thaliana seeds, with a focus on endosperm. Endosperm, the primary site of gene imprinting in flowering plants, mediates the relationship between the maternal parent and the embryo 2.
Witryna13 kwi 2024 · In eukaryotes, dynamins and dynamin-related proteins (DRPs) are high–molecular weight GTPases responsible for mechanochemical fission of organelles or membranes. Of the six DRP subfamilies in Arabidopsis thaliana, AtDRP1 and AtDRP2 family members serve as endocytic accessory proteins in clathrin-mediated … Witryna1 paź 1999 · In Arabidopsis, the fertilized egg undergoes an asymmetric transverse cleavage to produce a small cytoplasmically dense apical cell and a large vacuolated basal cell. The apical cell divides many times and generates cells that comprise most of the embryonic structures found in the mature seed ( Bowman and Mansfield, 1994 ).
Witryna11 kwi 2014 · Working in Arabidopsis, Costa et al. (p. 168; see the Perspective by Bayer) identified a trio of small signaling peptides that derive from the endosperm but that regulate growth of the embryo. RNA interference was used to down-regulate expression of all three peptides. Fertilization was not affected, but seed growth was.
WitrynaGenomic imprinting causes the expression of an allele depending on its parental origin. In plants, most imprinted genes have been identified in Arabidopsis endosperm, a transient structure consumed by the embryo during seed formation.
