Hormonal Control of Root Hair Growth and Development
Physiological and morphological studies on root hairs trace back to the 18th Century (see Farr 1927a,b,c). The pattern of root hair growth and development is under the influence of various factors including ge...

A single treatment of rice seedlings with 5-azacytidine induces heritable dwarfism and undermethylation of genomic DNA
A single exposure of germinated rice seeds (Oryza sativa) to either of the DNA demethylating agents 5-azacytidine (azaC) or 5-azadeoxycytidine (azadC) induced dwarf plants. At maturity, seeds treated with azaC ex...

Endogenous gibberellins in the shoots of normal- and bush-typeCucumis sativus L.
Endogenous gibberellins (GAs) in the shoots of normal- (cv. Yomaki, YO) and bush-type (cv. Spacemaster, SP) cultivars of cucumber (Cucumis sativus L.) grown under natural conditions were analyzed. From both YO an...

Light-controlled sugar-starch interconversion in epidermal chloroplasts of light-grown cucumber hypocotyl sections and its relationship to cell elongation
Sugar-starch interconversion in epidermal chloroplasts of light-grown cucumber hypocotyl sections as a regulatory mechanism of the osmotic potential of the cell was studied in relation to cell elongation. The ...

The mode of action of a morphactin, fluoren-9-carboxylic acid
Fluoren-9-carboxylic acid acts not only as an auxin but also as an gibberellin-antagonist. In the standard pea straight test (S5 section) for auxin it stimulated elongation, the optimum concentration being 10 mg/

Pseudogibberellin A1 as an inhibitor of the GA3-induced growth of rice seedlings
Pseudogibberellin A1 inhibited the GA3-induced growth of rice seedlings; this inhibition was completely overcome by increasing the concentration of GA3. It is concluded that pseudogibberellin A1 may act as an ant...

IAA-oxidase activity in light grown cucumber hypocotyls treated with helminthosporol
Helminthosporol (H-ol) promoted the growth of light grown cucumber hypocotyls. The IAA-oxidase activity per dry weight of the hypocotyl of H-ol treated materials was less than that of controls. There was an in...

Plant-Growth Activity of α-Alkylphenylacetic Acids and 1,2-Benzo-1-cycloalkene-3-carboxylic Acids
1,2,3,4-Tetrahydro-1-naphthoic acid (1,2-benzo-1-cyclohexene-3-carboxylic acid) was found to have a high plant-growth activity. Its lower homologue, 1-indancarboxylic acid (1,2-benzo-1-cyclopentene-3-carboxylic a...
