Characterization of Movement from theHydrotropism : the Timing of Root Cap in the AgravitropicPerception and Signal Pea Mutant Ageotropum

چکیده
grayiperception in roots. The time required for transduction and transmission in the hydrotropic respQnse of ageotropum was compared to the time requireme"t in the grayity response of Alaska pea roots. We determined that threshold time for perception of an osmotic stimulation in the root cap is yery rapid, occurring in less than 2min following the application of sorbitol to the root cap. Furthermore, a single 5 min exposure of sorbitol to the root cap fully induced a hydrotropic response. We also found that transduction and transmission of an osmotic stimulus

Characterization of hydrotropism: the timing of perception and signal movement from the root cap in the agravitropic pea mutant ageotropum.
In recent years, experiments have demonstrated that the gravity response of roots can be separated from the hydrotropic response by using the agravitropic pea mutant ageotropum. Though this mutant has been a useful tool for demonstrating the existence of the hydrotropic response of roots, little is known about how perception, transduction, transmission, and the growth response is accomplished. ...
متن کاملStimulation of root elongation and curvature by calcium.
Ca2+ has been proposed to mediate inhibition of root elongation. However, exogenous Ca2+ at 10 or 20 millimolar, applied directly to the root cap, significantly stimulated root elongation in pea (Pisum sativum L.) and corn (Zea mays L.) seedlings. Furthermore, Ca2+ at 1 to 20 millimolar, applied unilaterally to the caps of Alaska pea roots, caused root curvature away from the Ca2+ source, whi...
متن کاملAboveground to root biomass ratios in pea and vetch after treatment with organic fertilizer
Some growth parameters of pea (cv. Pleven 4) and vetch (cv. Obrazets 666) after treatment with organic fertilizer were studied in a field trial carried out at the Institute of Forage Crops, Pleven, Bulgaria. Humustim as organic fertilizer was applied through presowing treatment of seeds, treatment during vegetation and combination between both, at different doses. Ratios of aboveground weight t...
متن کاملAnalysis of apical hook formation in Alaska pea with a 3-D clinostat and agravitropic mutant ageotropum
The formation of the apical hook in dicotyledonous seedlings is believed to be effected by gravity in the dark. However, this notion is mostly based on experiments with the hook formed on the hypocotyl, and no detailed studies are available with the developmental manners of the hook, particularly of the epicotyl hook. The present study aims at clarifying the dynamics of hook formation including...
متن کاملIdentification and Functional Characterization of Arabidopsis icl Mutant Under Trehalose Feeding in Light and Dark Conditions
Trehalose is a non-reducing sugar that plays an important role in plant growth and development. To study the role of trehalose on lipid metabolism and gluconeogenesis, Arabidopsis thaliana wild type (WT) and TreF (a line expressing trehalase) were grown on ½ MS medium with or without 100 mM sucrose and or trehalose in light or continuous darkness. In dark, trehalose leads skotomorphoge...
