Experimental Studies on Lateral Root Formation in Radish Seedling Roots: II. Analysis of the Dose-Response to Exogenous Auxin.
Application of indoleacetic acid (IAA) and other auxins causes cultured radish (Raphanus sativus L. ;Scarlet Globe') seedling root segments to produce an increased frequency (FR, no. cm(-1)) of lateral roots (LR); in the absence of auxin, segments spontaneously form about 6 LR cm(-1). A dose-response study has revealed that the increase in FR follows a biphasic Michaelis-Menten relationship wit...

15 صفحه اولEffects of Cycloheximide on Indoleacetic Acid-induced Ethylene Production in Pea Root Tips.
Cycloheximide inhibited ethylene production in excised pea root tips treated with high levels of indoleacetic acid (100 mum and 10 mum). In contrast, cycloheximide did not inhibit ethylene production induced by a lower concentration (1 mum) of indoleacetic acid unless it was added 2 hours before the indoleacetic acid treatment. These observations suggest that indoleacetic acid has two effects o...
متن کاملArabidopsis thaliana RALF1 opposes brassinosteroid effects on root cell elongation and lateral root formation
Rapid alkalinization factor (RALF) is a peptide signal that plays a basic role in cell biology and most likely regulates cell expansion. In this study, transgenic Arabidopsis thaliana lines with high and low levels of AtRALF1 transcripts were used to investigate this peptide's mechanism of action. Overexpression of the root-specific isoform AtRALF1 resulted in reduced cell size. Conversely, AtR...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
