Xylogen makes plant channels
innia are, according to a gardening website, " uncommonly beautiful " and " available in a riot of colors to satisfy any garden plan. " These plants from the daisy family are also a great model system for studying the formation of xylem—the woody channels in plants that conduct fluid and nutrients. Now, Hiroyasu Motose, Munetaka Sugiyama, and Hiroo Fukuda (University of Tokyo, Japan) have ident...
متن کاملChloride channels and endocytosis: ClC-5 makes a dent.
Ion channels are ubiquitous pore-forming membrane proteins found in virtually every cell of every living organism. In mammals, a vast array of ion channel types participate in numerous vital physiological processes such as membrane excitability, cell volume regulation, signal transduction, secretion, and absorption. Therefore, it is not surprising that hereditary conditions can occur because of...
متن کاملAnd Baby Makes Three: Genomic Imprinting in Plant Embryos
Genomic imprinting results in the preferential expression of alleles after fertilization, depending on their parent of origin. Imprinting is epigenetically controlled and has evolved independently in plants and animals [1]. This striking convergence, combined with a degree of conservation within kingdoms, strongly suggests that imprinting confers a significant fitness advantage. Current thinkin...
متن کاملUpdate on Genetic Identities of Plant Calcium Channels Plant Calcium-Permeable Channels
The transient elevation of free calcium ion concentration in the cytosol and organelles of plant cells is a wellestablished phenomenon. As discussed in this Focus issue on calcium signaling, these elevations occur in response to a range of biotic and abiotic stimuli (McAinsh and Pittman, 2009; Dodd et al., 2010). Recently, transcriptomic analyses coupled with calcium determinations have demonst...
متن کاملPlant K+ channels: structure, activity and function.
Introduction In plants as in animals, K+ channel activity is the major determinant of cell membrane conductance [1,2]. Kt channels are therefore involved in central physiological processes such as setting the resting cell membrane potential, transducing signals and shaping action-potential waveforms. In addition, in plant cells, K t channel activity is thought to be involved in long-term fluxes...
