Metabolite Screening From Pinus pinea Needles Reveals (+)‐Isocupressic Acid as a Key Phytotoxin for Weed Management [PDF]
Phytochemical Analysis, Volume 36, Issue 8, Page 2374-2384, December 2025.This study explores the phytotoxicity of Pinus pinea needle extracts and metabolites to evaluate their potential for controlling dicotyledonous weeds. A strategy based on GC–MS, NMR, and optical methods revealed an array of aromatic compounds which are of crucial interest for phytochemical research. Hence, a bio‐guided purification led to the isolation

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.

Blue-Light-Induced Shrinking of Protoplasts from Maize Coleoptiles and Its Relationship to Coleoptile Growth [PDF]
Plant Physiology, 1997 Abstract Protoplasts isolated from red-light-grown maize (Zea mays L.) coleoptiles shrank transiently upon brief exposure (e.g. 30 s) to blue light under background irradiation with red light. The maximal volume reduction (about 4% at a saturating fluence) occurred about 5 min after blue-light stimulation.

Avena Coleoptile Elongation: Stimulation by Fluorophenylalanine [PDF]
Plant Physiology, 1969 A 100 to 150% stimulation of Avena coleoptile segment elongation by the amino acid analogue p-fluorophenylalanine (FPA) has been observed. The effect is reversed by phenylalanine and is not seen with comparable concentrations of sodium fluoride. FPA does not alter elongation of red-irradiated segments.

Phototropic Dosage-Response Curves for Oat Coleoptiles [PDF]
Plant Physiology, 1963 In 1934, Du Buy and Nuernbergk (9) compiled from a number of sources the first extensive phototropic dosage-response curve for oat coleoptiles. The various features of this curve, first positive curvature, first negative curvature, and second and third positive curvature, are now well known.

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 ...

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.

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 ...

Quiescin Sulfhydryl Oxidase‐Like 1 Positively Regulates Seed Dormancy in Rice
Plant Biotechnology Journal, EarlyView.ABSTRACT Seed dormancy is an adaptive strategy that enables plants to survive adverse environmental conditions. In agricultural contexts, an optimal level of dormancy is essential: Insufficient dormancy can result in preharvest sprouting, while excessive dormancy may lead to uneven germination and poor stand establishment in subsequent crops.
