(Submitter supplied) Salicylic acid (SA) and ethylene (ET) are two important plant hormones that regulate numerous plant growth, development, and stress response processes. Previous studies have suggested functional interplay of SA and ET in defense response, but precisely how these two hormones co-regulate plant growth and development processes remains unclear. The present findings reveal an antagonism between SA and ET in apical hook formation, a process that ensures successful soil emergence of dicotyledonous etiolated seedlings. more...

Under these growth conditions symptoms of Fe deficiency develop in the 0 Fe plants. Ethylene is known to promote Fe acquisition responses. more...

(Submitter supplied) Root hairs are an extensive structure of root epidermal cells and are critical for nutrient acquisition, soil anchorage, and environ- mental interactions in sessile plants. The phytohormone ethylene (ET) promotes root hair growth and also mediates the effects of different signals that stimulate hair cell development. However, the molecular basis of ET-induced root hair growth remains poorly understood. more...

(Submitter supplied) Ethylene is a gaseous hormone that plays important roles in plant growth, development and stress responses. EIN3 was identified as a plant-specific transcription factor and its protein level rapidly increases upon ethylene treatment. We found that activation of EIN3 and EIN3-like 1 (EIL1) is both necessary and sufficient for ethylene-induced enhancement of seedling greening, as well as repression of the accumulation of protochlorophyllide, a phototoxic intermediate of chlorophyll synthesis. more...

(Submitter supplied) Purpose: Next-generation sequencing (NGS) has been used to study the gene expression in Arabidopsis seedlings under air and ethylene treatment. The goal of this study is to uncover how TREE1 and its homologous gene DAZ3 are involved into gene expression regulation in response to ethylene.

(Submitter supplied) We report that ethylene enhances the TREE1 binding. We perform ChIP-sequencing of TREE1 using chromatins isolated from 3-day old etiolated pTREE1:TREE1-GFP seedlings treated with ethylene or air gas. Results show that ethylene enhances TREE1 binding in ethylene down regulated genes.

(Submitter supplied) Genome-wide direct targets of Arabidopsis NPR1 and HAC1 were identified by chromain immunoprecipitation followed by sequencing (ChIP-seq). For the study, we used Arabidopsis expressing NPR1:GFP or HAC1:mCherry under native NPR1 or HAC1 promoter, respectively. To identify direct targets both under salicylic acid-treated and untreated conditions, we performed ChIP-seq by using 2,6-dichloroisonicotinc acid (INA; synthetic SA analog)-treated and untreated NPR1:GFP or HAC1:mCherry transgenic Arabidopsis plants.

(Submitter supplied) Plants are aerobic organisms that rely on molecular oxygen for respiratory energy production. Hypoxic conditions, with oxygen levels ranging between 1% and 5%, usually limit aerobic respiration and affect plant growth and development. Here, we demonstrate that hypoxic microenvironment induced by active cell proliferation during the two-step plant regeneration process intrinsically represses the regeneration competence of callus in Arabidopsis thaliana. more...
