Ethylene hypocotyl
WebJan 8, 2024 · Ethylene signaling up-regulates MDP60 expression via PIF3 binding to the MDP60 promoter. MDP60 loss-of-function mutants exhibit much shorter hypocotyls, … WebHypocotyl elongation assay. One of the widely used assays in the field of photobiology is the investigation of the effect of changes in light quantity and quality on hypocotyl elongation. It is frequently used to study the growth promoting vs. growth repressing effects of application of plant hormones like ethylene.

WebOct 1, 2000 · Ethylene responses were blocked by using the etr1 ethylene-resistant mutant ( Chang et al., 1993 ), and it was found that the elongation of the etr1 mutant hypocotyl was inhibited by auxin to the same extent as the wild type (Fig. 4 ). Ethylene synthesis was blocked using AVG, a known inhibitor of ethylene synthesis ( Yang and Hoffman, 1984 ). WebIn the presence of ethylene, an exaggeration of the apical hook, a radially swollen short hypocotyl, and development of shorter roots can be noticed. PI3K overexpression resulted in seedlings showing triple response phenotype in the dark in the absence of ACC, an ethylene precursor, and might be caused by spontaneously elevated ethylene ...
WebSep 29, 2024 · Ethylene induces the triple response in dark-grown seedlings; this response is characterized by a strongly curved apical hook, shortening of the roots, and shortening and thickening of the hypocotyl ( Guzmán and Ecker, 1990; Wang et al., 2002 ). WebJun 21, 2016 · Ethylene regulated substantially more DEGs in the hypocotyl compared with shade at all harvest time points ( Fig. 2C ). Data analysis identified 6,668 and 4,741 genes (hereafter termed total DEGs) that were differentially expressed in hypocotyl at one or more of the three tissue harvest time points by ethylene and shade, respectively.
WebMar 12, 2003 · In this study, we used hypocotyl elongation as a system to investigate interactions between GA and ethylene or auxin and analysed their influence on the … WebJan 8, 2024 · Ethylene Signaling Mediates MDP60-Promoted Hypocotyl Cell Elongation According to microarray data and the positive role of ethylene on light-grown hypocotyl elongation, we hypothesized that MDP60 participates in ethylene signaling-promoted hypocotyl elongation. We first determined whether and how ethylene regulates MDP60 …
WebJul 31, 2015 · Ethylene has been shown to rapidly (within 10 min) affect microtubule orientation in Arabidopsis roots and hypocotyls, likely preventing cell elongation and facilitating radial swelling ( Le et al., 2004, 2005 ). The opposite process has been observed in upper hypocotyl cells when grown in the light ( Le et al., 2005 ).
WebOct 22, 2024 · Ethylene signaling plays a role in the regulation of hypocotyl elongation through the activation of different downstream transcription factors in Arabidopsis ( Zhong et al., 2012 ).
