Abscisic acid (ABA) is a phytohormone that regulates many physiological functions, such as plant growth, development and stress responses. The MAPK cascade plays an important role in ABA signal transduction. Several MAPK and MAPKK molecules are reported to function in ABA signaling; however, there have been few studies related to the identification of(More)
A major question is whether exposure to mixtures of low-dose endocrine disruptors (EDs) having different action mechanisms affects neurodevelopment differently than exposure to EDs individually. We therefore investigated the effects of fetal and neonatal exposure to three typical EDs - bisphenol A (BPA), di-(2-ethylhexyl)-phthalate (DEHP), and(More)
The Arabidopsis mitogen activated protein kinase kinase kinase (MEKK1) plays an important role in stress signaling. However, little is known about the upstream pathways of MEKK1. This report describes the regulation of MEKK1 activity during cold signaling. Immunoprecipitated MEKK1 from cold-treated Arabidopsis seedlings showed elevated kinase activity(More)
a large amount of glycinebetaine (betaine), and this metabolite is considered to have various protective effects on plant cells under stress conditions (Storey et al. 1977; Hanson and Wyse 1982; Sakamoto and Murata 2002). In chenopods, betaine is synthesized from choline by the action of choline monooxygenase (CMO) and betaine aldehyde dehydrogenase (BADH)(More)
