Two distinct EIN2 genes cooperatively regulate ethylene signaling in Lotus japonicus.
Leguminous plants establish a mutualistic symbiosis with bacteria, collectively referred to as rhizobia. Host plants positively and negatively regulate the symbiotic processes to keep the symbiosis at an appropriate level. Although the plant hormone ethylene is known as a negative regulator of symbiotic processes, the molecular mechanisms of ethylene signaling remain unresolved, especially in t...
متن کاملEIN2-Directed Translational Regulation of Ethylene Signaling in Arabidopsis
Ethylene is a gaseous phytohormone that plays vital roles in plant growth and development. Previous studies uncovered EIN2 as an essential signal transducer linking ethylene perception on ER to transcriptional regulation in the nucleus through a "cleave and shuttle" model. In this study, we report another mechanism of EIN2-mediated ethylene signaling, whereby EIN2 imposes the translational repr...
متن کاملEthylene insensitivity conferred by a mutated Arabidopsis ethylene receptor gene alters nodulation in transgenic Lotus japonicus.
BACKGROUND AND AIMS Transgenics are used to demonstrate a causal relationship between ethylene insensitivity of a seedling legume plant, the level of ethylene receptor gene expression, lateral root growth and Mesorhizobium loti-induced nodule initiation. METHODS Lotus japonicus plants expressing the dominant etr1-1 allele of the Arabidopsis thaliana gene encoding a well-characterized mutated ...
متن کاملLjCYC genes constitute floral dorsoventral asymmetry in Lotus japonicus.
Previous study shows that LjCYC2, a CYC-like TCP (TB1, CYC and PCFs) gene in the model legume, Lotus japonicus, is involved in dorsal petal development, which together with the other two homologous genes, LjCYC1 and LjCYC3, belongs to an LjCYC gene cluster. In this report, we modified the transformation system in L. japonicus, and constructed different RNAi transgenes to target different LjCYC ...
متن کاملThe WRKY Transcription Factor Genes in Lotus japonicus
WRKY transcription factor genes play critical roles in plant growth and development, as well as stress responses. WRKY genes have been examined in various higher plants, but they have not been characterized in Lotus japonicus. The recent release of the L. japonicus whole genome sequence provides an opportunity for a genome wide analysis of WRKY genes in this species. In this study, we identifie...
