The Plant Hormones: Their Nature, Occurrence, and Functions
Peter J. Davies
- pp 1-11
TLDR
Plant hormones are a group of naturally occurring, organic substances which influence physiological processes at low concentrations, mainly of growth, differentiation and development, though other processes, such as stomatal movement, may also be affected.Abstract:
Plant hormones are a group of naturally occurring, organic substances which influence physiological processes at low concentrations. The processes influenced consist mainly of growth, differentiation and development, though other processes, such as stomatal movement, may also be affected. Plant hormones1 have also been referred to as ‘phytohormones’ though this term is infrequently used.read more

Soil beneficial bacteria and their role in plant growth promotion: a review
TL;DR: Free-living soil bacteria beneficial to plant growth, usually referred to as plant growth promoting rhizobacteria (PGPR), are capable of promoting plant growth by colonizing the plant root and can inhibit phytopathogens.
Journal ArticleDOI
Plant Growth-Promoting Effects of Diazotrophs in the Rhizosphere
TL;DR: It is now clear that associative diazotrophs exert their positive effects on plant growth directly or indirectly through (a combination of) different mechanisms, and further elucidation of the different mechanisms involved will help to make associative Diazotrophic bacteria a valuable partner in future agriculture.

Plant Development Is Regulated by a Family of Auxin Receptor F Box Proteins
Nihal Dharmasiri,Sunethra Dharmasiri,Dolf Weijers,Esther Lechner,Masashi Yamada,Lawrence Hobbie,Jasmin S. Ehrismann,Gerd Jürgens,Mark Estelle +8 more
TL;DR: It is shown that three additional F box proteins, called AFB1, 2, and 3, also regulate auxin response and collectively mediate auxin responses throughout plant development.

TL;DR: In this article, the TAA family produces indole-3-pyruvic acid (IPA) and the YUC family functions in the conversion of IPA to IAA in Arabidopsis.

The role of gibberellin signalling in plant responses to abiotic stress
TL;DR: The evidence for the role of GA in these processes, and the regulation of the GA signalling pathway on exposure to abiotic stress are reviewed, are reviewed.

The Power of Movement in Plants
TL;DR: This chapter discusses the circumnutating movements of seedling plants, modified circumnutation, and localised sensitiveness to gravitation and its transmitted effects.
Book
Power of Movement in Plants
TL;DR: In this article, the circumnutating movements of seedling plants have been studied and the effects of these movements on the growth and development of seedlings have been discussed, as well as the sensitivity of the radicle of a seed to light and other irritants.
Journal ArticleDOI
How do plant growth substances work? II
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.

The interaction between auxin and ethylene and its role in plant growth.
Stanley P. Burg,Ellen A. Burg +1 more
TL;DR: It is shown that all of these problems arise under the conditions commonly used to study auxin metabolism, and the significance of this finding will be discussed with special reference to a postulated mechanism of ethylene action.

Regulators of Cell Division in Plant Tissues XII. A Cytokinin Bioassay Using Excised Radish Cotyledons
TL;DR: A rapid bioassay for cytokinins is described, based on the ability of these compounds to promote markedly the expansion of radish cotyledons excised soon after seed germination.
