Indoleacetaldehyde in Cucumber Seedlings [PDF]

open access: yesPlant Physiology, 1978
The presence of indoleacetaldehyde in cucumber (Cucumis sativus L.) cotyledons was demonstrated by thin layer chromatographic R(F) values in three solvent systems, by the formation and hydrolysis of a bisulfite adduct, and by chemical reduction to indoleethanol and oxidation to indoleacetic acid. Bioassays indicated a minimum indoleacetaldehyde content

A novel gibberellin promotes seedling establishment [PDF]

open access: yes, 2019
A previously unknown biologically active gibberellin present in seeds of Arabidopsis thaliana is formed by hydration of the gibberellin precursor GA12 through the action of GAS2, a 2-oxoglutarate-dependent dioxygenase that decreases sensitivity to ...

SEEDLINGS [PDF]

open access: yesNew Phytologist, 1987
SummaryThe factors which cause the death of seedlings were examined and an attempt was made to determine the selective forces to which they are subjected in the field. After briefly dealing with the difficulties of defining a seedling, I examine a few cases from the recent literature in which the causes of seedling mortality are identified and ...

El cáncer en la función mitocondrial

open access: yesRevista de la Facultad de Medicina, 2018
Metabolism alterations are associated with the loss of mitochondrial function in tumor cells. Current research discuss whether such loss is evident in function itself, or if cells can provide maximum stability to its functions. More studies are needed to
