Effect of the Roots on the Production of Auxin by the Coleoptile [PDF]
Proceedings of the National Academy of Sciences, 1937 Since it had been shown by Skoog (1936, 1937) that removal of the seed (endosperm and scutellum) of Avena seedlings greatly reduces the production of auxin in the coleoptile tip, the question arose whether removal of the root system would have any effect upon the auxin relations of the plant. This was the purpose of the present investigation.

GEOTROPIC CURVATURE OF AVENA COLEOPTILES [PDF]
The Journal of General Physiology, 1932 On page 139, Fig. 3, and page 140, Fig. 4, the left hand ordinate should read: See PDF for Equation The attached slip may be cut in half on the vertical line, and the corrected ordinates should be pasted over the present incorrect ones.

Transcript Profiling of the Anoxic Rice Coleoptile [PDF]
Plant Physiology, 2007 AbstractRice (Oryza sativa) seeds can germinate in the complete absence of oxygen. Under anoxia, the rice coleoptile elongates, reaching a length greater than that of the aerobic one. In this article, we compared and investigated the transcriptome of rice coleoptiles grown under aerobic and anaerobic conditions.

THE GROWTH AND RESPIRATION OF THE AVENA COLEOPTILE [PDF]
Journal of General Physiology, 1936 1. Transport of the plant growth hormone into the Avena coleoptile as well as the action of the hormone on cell elongation in the coleoptile are shown to depend upon aerobic metabolism. 2. Crystalline auxine, in contrast with impure preparations, affects neither the magnitude nor the respiratory quotient of coleoptile respiration.

Magnetophoretic induction of curvature in coleoptiles and hypocotyls [PDF]
Journal of Experimental Botany, 1997 Coleoptiles of barley (Hordeum vulgare) were positioned in a high gradient magnetic field (HGMF, dynamic factor gradient of H(2)/2 of 10(9)-10(10) Oe2 cm-1), generated by a ferromagnetic wedge in a uniform magnetic field and rotated on a 1 rpm clinostat. After 4 h 90% of coleoptiles had curved toward the HGMF.

Auxin Relationships of the Rice Coleoptile [PDF]
Plant Physiology, 1954 The work reported here concerns the well known fact that the rice coleoptile elongates more rapidly and more extensively under water than in air. Decapitation experiment carried out with seedlings in air or under water, as well as experiment done with the growth response to the added IAA of floating or submerged coleoptile sections suggest that the ...

Induction of Coleoptile Elongation by Carbon Dioxide [PDF]
Plant Physiology, 1971 The ability of CO(2) to induce elongation of Avena sativa coleoptile segments was examined with the use of a high resolution growth-recording device. CO(2)-saturated water causes an 8- to 16-fold promotion in the rate of elongation within 1 minute.

Changes in the Autolytic Activities of Maize Coleoptile Cell Walls during Coleoptile Growth [PDF]
Plant and Cell Physiology, 1997 Autolytic activities of coleoptile cell walls were measured in developing maize seedlings. The major neutral sugar components of the cell wall polysaccharides were arabinose, xylose and glucose. The quantities of all these components per coleoptile increased for 5 d after germination, suggesting that levels are augmented by biosynthetic processes ...

Effect of Red Light on Coleoptile Growth [PDF]
Plant Physiology, 1974 The effects of red light in reducing the growth of the oat (Avena sativa L.) coleoptile and the synthesis of auxin in the coleoptile tip are detectable 2 hours after treatment and become more pronounced with time. When the coleoptile tip is supplied with additional tryptophan the synthesis of auxin is doubled both in darkness and when exposed to red ...

Cell Wall Development in Maize Coleoptiles [PDF]
Plant Physiology, 1984 The physical bases for enhancement of growth rates induced by auxin involve changes in cell wall structure. Changes in the chemical composition of the primary walls during maize (Zea mays L. cv WF9 x Bear 38) coleoptile development were examined to provide a framework to study the nature of auxin action.
