Overexpression of barley BAX inhibitor 1 induces breakdown of mlo-mediated penetration resistance to Blumeria graminis.
Cell death regulation is linked to pathogen defense in plants and animals. Execution of apoptosis as one type of programmed cell death in animals is irreversibly triggered by cytochrome c release from mitochondria via pores formed by BAX proteins. This type of programmed cell death can be prevented by expression of BAX inhibitor 1 (BI-1), a membrane protein that protects cells from the effects ...
متن کاملMammalian Bax-induced plant cell death can be down-regulated by overexpression of Arabidopsis Bax Inhibitor-1 (AtBI-1).
We recently isolated the AtBI-1 (Arabidopsis Bax Inhibitor-1) gene, the expression of which suppressed Bax-induced cell death in yeast. To determine whether the same is true in the plant system, transgenic Arabidopsis plants overexpressing Bax protein under a dexamethasone (DEX)-inducible promoter were generated. On DEX treatment, such transgenic plants exhibited marked cell death at the whole-...
متن کاملMicrodomain Organization of the Plasma Membrane in Keratinocytes
Plasma membrane of the keratinocyte is organized in a domain structure comprising the nanoscale areas of the lipid in the liquid ordered state (comparable to lipid rafts) surrounded by the liquid-disordered lipid fraction. In this review we summarize the current state of knowledge on the microdomain organization of the keratinocytes plasma membrane. Application of the fluorescent derivative of ...
متن کاملIn vitro phosphorylation of plant plasma membrane proteins in response to the proteinase inhibitor inducing factor.
A polygalacturonide purified from a tomato leaf pectic polysaccharide that induces the systemic synthesis of proteinase inhibitors in tomato plants enhances the phosphorylation of specific proteins in plasma membrane fractions isolated from tomato and potato leaves. In tomato plasma membranes, two proteins of 34 and 29 kDa show enhanced phosphorylation in response to the polyuronide. In potato ...
متن کاملFeeding-fasting dependent recruitment of membrane microdomain proteins to lipid droplets purified from the liver
Lipid droplets (LDs) are cellular stores of neutral fat that facilitate lipid and protein trafficking in response to metabolic cues. Unlike other vesicles, the phospholipid membrane on the LD is a monolayer. Interestingly, this monolayer membrane has free cholesterol, and may therefore contain lipid microdomains that serve as a platform for assembling proteins involved in signal transduction, c...
