TLDR
In this article, the response of cereal aleurone to gibberellic and abscisic acids (GA and ABA), particularly with reference to α-amylase synthesis, has made a significant contribution to our understanding of GA action in plant cells especially as it relates to the control of protein synthesis.Abstract:
Study of the response of cereal aleurone to gibberellic and abscisic acids (GA and ABA, respectively), particularly with reference to α-amylase synthesis, has made a significant contribution to our understanding of GA action in plant cells especially as it relates to the control of protein synthesis. While much of the work has been carried out using isolated aleurone from a single cultivar of barley (“Himalaya”), it seems so far that the principles which have emerged from this system can be applied to in vivo behaviour of other cereal grains.read more

Biochemistry and Physiology of Plant Hormones
TL;DR: The dominant objective of Biochemistry and Physiology of Plant Hormones is to summarize, in a reasonably balanced and comprehensive way, the current state of fundamental knowledge regarding the major kinds of hormones and the phytochrome pigment system.
Journal ArticleDOI
Regulatory mechanisms involved in the transition from seed development to germination.
TL;DR: In this paper, the transition from seed development to germination is discussed, and the regulatory mechanisms involved in the transition are discussed, as well as a discussion of the role of genetic information in the process.

Key Role for Endogenous Gibberellins in the Control of Seed Germination

Integrated control of seed maturation and germination programs by activator and repressor functions of Viviparous-1 of maize.
TL;DR: It is shown that VP1 also inhibits induction of the germination-specific alpha-amylase genes in aleurone cells of the developing seed and thereby appears to be involved in preventing precocious hydrolyzation of storage compounds accumulating in the endosperm.

Gibberellins and Seed Development in Maize. I. Evidence That Gibberellin/Abscisic Acid Balance Governs Germination versus Maturation Pathways
TL;DR: It is shown that a GA deficiency early in seed development, induced genetically or via biosynthesis inhibitors, suppresses vivipary in ABA-deficient developing kernels, and the resulting seeds have both desiccation tolerance and storage longevity.

Journal ArticleDOI
Two barley alpha-amylase gene families are regulated differently in aleurone cells.
TL;DR: Results of primer extension experiments utilizing probes for the 5' coding regions of both types of mRNA are consistent with some of the features of these predicted structures, and there appears to be only one major type of type B gene transcribed.

Abscisic acid in developing wheat grains and its relationship to grain growth and maturation.
TL;DR: It is suggested that the accumulation of ABA at the later stages of grain growth prevents precocious germination and premature hydrolysis of starch reserves of the morphologically mature but still unripe grain.
