Principles of plant nutrition
Konrad Mengel,Ernest A. Kirkby +1 more
TL;DR: In this article, the Soil as a Plant Nutrient Medium is discussed and the importance of water relations in plant growth and crop production, and the role of water as a plant nutrient medium.

The Mineral Nutrition of Higher Plants
David T. Clarkson,John B. Hanson +1 more
TL;DR: This review of mineral nutrients shall not be considering two most important, but frequently reviewed, aspects of the subject, namely biological fixation of N/sub 2/ and its assimilation and mechanisms of membrane transport.

Auxin Regulates the Initiation and Radial Position of Plant Lateral Organs
TL;DR: The results show that auxin is required for and sufficient to induce organogenesis both in the vegetative tomato meristem and in the Arabidopsis inflorescence meristsem, and it is proposed that Auxin determines the radial position and the size of lateral organs but not the apical–basal position or the identity of the induced structures.

Stomatal size, speed and responsiveness impact on photosynthesis and water use efficiency.
Tracy Lawson,Michael R. Blatt +1 more
TL;DR: Manipulating guard cell transport and metabolism is just as, if not more likely to yield useful benefits as manipulations of their physical and anatomical characteristics, to improve water use efficiency without substantial cost to photosynthetic carbon fixation.

Role of Stomata in Plant Innate Immunity and Foliar Bacterial Diseases
TL;DR: It is shown that stomata can play an active role in limiting bacterial invasion as part of the plant innate immune system, and microbial and environmental regulation of stomatal closure and opening could fill gaps in the understanding of bacterial pathogenesis, disease epidemiology, and microbiology of the phyllosphere.

Phloem Loading of Sucrose
TL;DR: The results are discussed in terms of sucrose loading being coupled to the co-transport of protons (and membrane potential) in a manner consistent with the chemiosmotic hypothesis of nonelectrolyte transport.

Phloem Loading of Sucrose pH Dependence and Selectivity
TL;DR: The results are discussed in terms of sucrose loading being coupled to the co-transport of protons (and membrane potential) in a manner consistent with the chemiosmotic hypothesis of nonelectrolyte transport.

A proton-cotransport system in a higher plant: Sucrose transport in Ricinus communis
TL;DR: The results suggest that active sucrose transport in this tissue is mediated by an electrogenic proton cotransport system.

Correlation between cell enlargement in pea internode segments and decrease in the pH of the medium of incubation: I. Effects of fusicoccin, natural and synthetic auxins and mannitol
TL;DR: In this paper, the authors showed that the growth-promoting activity of IAA and FC is mediated by the capacity of these compounds to induce a decrease of pH in the cell wall and thus an increase of its plastic extensibility.
