Identification and characterization of stretch-activated ion channels in pollen protoplasts.

abstract：:The knotted1 (kn1) homeobox (knox) gene family was first identified through gain-of-function dominant mutants in maize (Zea mays). Class I knox members are expressed in meristems but excluded from leaves. In maize, a loss-of-function phenotype has only been characterized for kn1. To assess the function of another knox...

abstract：:Eukaryotic initiation factor 4A (eIF4A) is a highly conserved RNA-stimulated ATPase and helicase involved in the initiation of messenger RNA translation. Previously, we found that eIF4A interacts with cyclin-dependent kinase A (CDKA), the plant ortholog of mammalian CDK1. Here, we show that this interaction occurs onl...

abstract：:Computing techniques are used to simulate the course of uptake of K(+), Na(+), and Cl(-) by low-salt roots. Measurements of the fluxes of these ions in high-salt roots are used to calculate membrane permeabilities, which are then used to calculate cell uptake. In this way it is possible to test the predictive value of...
