Experimental infection of suckling-ferrets with viruses of the coxsackie group isolated from cases of infantile gastroenteritis
Group A Coxsackie viruses have been isolated from the stools of patients suffering from infantile gastroenteritis. Strains of both group A and group B Coxsackie virus produced illness and death in suckling-fer...

Spontaneous chromosome inversions of guatemalan teosintes (Zea mexicana)
Two paracentric inversions,In3 andIn9, were found in the F1 hybrids of maize and Florida teosinte and these inversions were contributed by the teosinte parent. The length ofIn3 was equivalent to about 35 percent ...

The Mm. levatores costarum longi in some catarrhine monkeys
In this paper, the authors mentioned that the M. levator costae longus is present, even if very rarely, in two species of macaque; that the nerve supply is not by the ramus anterior but by the ramus posterior ...

Abscisic-acid-stimulated rooting of stem cuttings
Abscisic acid (ABA) has been found to stimulate rooting of stem cuttings of mung beans and English ivy. ABA partially overcame the inhibitory effect of gibberellic acid on root formation of mung bean cuttings ...

Changes in endogenous growth regulators in nasturtium leaves during senescence
By use of lettuce-hypocotyl and wheat-coleoptile bioassay, the presence of both gibberellin (GA)-like and abscisic-acid(ABA)-like components in acidic ethyl-acetate extracts of fully expanded nasturtium (Tropaeol...

Effects of abscisic acid on in vitro growth of cotton fiber
Abscisic acid (ABA) inhibits in vitro growth of cotton (Gossypium hirsutum L.) fiber and is effective only when applied during the first four days of culture started on the day of anthesis. Abscisic acid causes a...

Modern and Paleocene Metasequoias: A Comparison of Foliage Morphology
Silicified peat from the Paleocene Fort Union Group in North Dakota has been studied using thin-section and peel methods. The internal structure of foliage identified as Metasequoia sp . is well preserved and is ...

Introduction
The acid metabolism of certain succulent plants, now known as Crassulacean Acid Metabolism (CAM) has fascinated plant physiologists and biochemists for the last one and a half centuries. However, since the bas...

Chapter
Taxonomy and Geographical Distribution of CAM Plants
Crassulacean Acid Metabolism has been documented in at least 18 flowering plant families (Table 1.1). As of 1977, there were recorded in the literature 109 genera and over 300 species of flowering plants (cf. ...

Chapter
Terminology
Different terms have been used to describe the CAM phenomenon. In the English literature, the term Crassulacean Acid Metabolism is established and generally accepted because most species within the family Cras...

Chapter
Morphology, Anatomy, and Ultrastructure of CAM Plants
CAM is usually regarded as a typical feature of succulents because of its occurrence in many succulent species. However, two questions must be asked:
- ...

Chapter
The Metabolic Pathway of CAM
CAM is characterized by two segmental major metabolic sequences separated in time, one occurring in the night and the other during the day. The considerations of this chapter follow this sequential scheme. Hen...

Gas Exchange of CAM Plants
Historical aspects of gas exchange in CAM plants have been reviewed by several authors (Wolf, 1960; Ranson and Thomas, 1960; Beevers et al., 1966; Neales, 1975; Osmond, 1978). The net CO2 uptake occurring at nigh...

Chapter
Control and Modification of CAM
Perhaps the most significant feature of CAM is the regular, rhythmic diurnal cycle in which biochemical and physiological events follow very closely in time. Furthermore, some of the CAM activities may undergo...

Ecology, Productivity, and Economic Use of CAM Plants
As far as is known, Wilhelm Pfeffer (1845–1920) was the first to recognize that CAM might have an ecological significance. Pfeffer interpreted the nocturnal acid accumulation of succulents as a mechanism to co...

Irrigation magnifies CAM-photosynthesis in Opuntia basilaris (Cactaceae)
Measurements of acid metabolism and gas exchange were carried out four times during a year to assess the relative importance of temperature and the accompanying seasonal change to the carbon metabolism of Opuntia...
