Calcium Signaling In Arabidopsis
Calcium signaling in ''Arabidopsis'' is a calcium in biology, calcium mediated signalling pathway that ''Arabidopsis'' plants use in order to respond to a stimuli. In this pathway, Ca2+ works as a long range communication ion, allowing for rapid communication throughout the plant. Systemic changes in metabolites such as glucose and sucrose takes a few minutes after the Stimulus (physiology), stimulus, but gene Transcription (biology), transcription occurs within seconds. Because hormones, peptides and RNA travel through the vascular system at lower speeds than the plants response to wounds, indicates that Calcium in biology, Ca2+ must be involved in the rapid signal propagation. Instead of local communication to nearby Cell (biology), cells and tissues, Ca2+ uses Mass flow (life sciences), mass flow within the vascular system to help with rapid transport throughout the plant. Ca2+ moving through the xylem and phloem acts through a “calcium signature” Receptor (biochemistry), re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabidopsis Thaliana Kz08
''Arabidopsis'' (rockcress) is a genus in the family Brassicaceae. They are small flowering plants related to cabbage and Mustard plant, mustard. This genus is of great interest since it contains thale cress (''Arabidopsis thaliana''), one of the model organisms used for studying plant biology and the first plant to have its entire genome sequenced. Changes in thale cress are easily observed, making it a very useful model. Status Currently, the genus ''Arabidopsis'' has nine species and a further eight subspecies recognised. This delimitation is quite recent and is based on morphological and molecular phylogenies by O'Kane and Al-Shehbaz and others. Their findings confirm the species formerly included in ''Arabidopsis'' made it polyphyletic. The most recent reclassification moves two species previously placed in ''Cardaminopsis'' and ''Hylandra'' and three species of ''Arabis'' into ''Arabidopsis'', but excludes 50 that have been moved into the new genera ''Beringia (plant), Ber ...
