TL;DR: It is concluded that a hormonal concept which includes control by changes in growth substance concentration fails to explain the developmental phenomena under examination and a role for growth substances as integrating agents is suggested and the notion of quantitative tissue sensitivity variation is developed to explainThe major growth patterns of developing shoots.

Abstract: . Despite intensive research effort, the role of growth substances in the life of the intact growing plant is far from clear. Two reasons are suggested which may account for the lack of progress. The first is the failure to recognize the unique aspects of plant development. These which are expressed by the regenerative, organizational and developmental plasticity of the meristem probably result from the possession of growth substances. The second is the concept of growth substances as hormones. This represents the main conceptual thrust of research and is considered critically, starting with the historical system, the coleoptile and dealing with other major growth substance systems in turn. It is concluded that a hormonal concept which includes control by changes in growth substance concentration fails to explain the developmental phenomena under examination. A role for growth substances as integrating agents is suggested and the notion of quantitative tissue sensitivity variation is developed to explain the major growth patterns of developing shoots.

Inhibition of ethylene biosynthesis and action in cut carnations (Dianthus caryophyllus L.) by aminotriazole
TL;DR: No morphological or respiratory responses to the application of exogenous ethylene at 10 μl·liter -1 were observed, a result indicating that prolonged aminotriazole treatment inhibited ethylene action.
The effect of defoliation environment on primary growth allocation and secondary tiller recruitment of two bunchgrasses
TL;DR: Results suggest that tiller recruitment was limited by nutrient demand of primary structures, a consequence of which is that T. Triandra will recruit more tillers than E. curvula when defoliation opens up space, accounting for T. triandra's dominance on more regularly-defoliated treatments.

Translocation and Metabolism of Endosperm-Applied [2-14C] Indoleacetic Acid in Etiolated Avena sativa L. Seedlings
David L. Jackson,James A. McWha +1 more
TL;DR: It was concluded that translocation of free IAA directly from the endosperm is probably not a significant source offree IAA in the shoot, mainly because even small amounts of [(14)C]IAA introduced into the endOSperm were rapidly metabolized.

TL;DR: Firn et al. as mentioned in this paper discuss the possibility that changes in the number of receptors or modifications of the affinity of the receptor, also differences in the expression of different receptor sites may contribute to the observed phenomena of differential phytohormone sensitivity.

TL;DR: In this article, the authors present a collection of newly written, integrated, illustrated reviews describing their knowledge of plant hormones and the experimental work which is the foundation of this knowledge, which is intended to serve as a text and guide to the literature for graduate level courses in the plant hormones.
Transient and Stable Expression of the Firefly Luciferase Gene in Plant Cells and Transgenic Plants

TL;DR: Although light was detected in most organs in intact, transgenic plants (leaves, stems, and roots), the pattern of luminescence appeared to reflect both the organ-specific distribution of Luciferase and the pathway for uptake of luciferin through the vasculature of the plant.
