A review of polyamine biosynthesis, catabolism, derivatives and conjugates in plants, and of
growth regulation by polyamines, membranes and senescence as affected by polyamines …

Our entry into the polyamine field was accidental. As plant physiologists interested in the
regeneration of entire plants from isolated single cells and protoplasts, we had turned our …

The decade since the publication of the third edition of this volume has been an era of great
progress in biology in general and the plant sciences in particular. This is especially true …

Recent developments in the metabolism and function of polyamines in plants is presented.
Polyamines appear to be involved in a wide range of plant processes, however their exact …

Some chemicals occurring naturally within plant tissues (ie endogenously), have a
regulatory, rather than a nutritional role in growth and development. These compounds …

A cutting is in a thermodynamically unfavourable state from the time it is prepared [1]. Part of
the physical and physiological support, the root system, is gone. Only a new root system can …

Root development is under the control of hormonal, metabolic, and environmental cues that
can act on genetically-controlled developmental programmes and thus affect the plasticity of …

Of seventy-five actinomycetes isolated from a bean rhizosphere in the United Arab Emirates,
an isolate of Streptomyces griseoluteus (WT) was found to be capable of producing …

This review develops arguments for rooting as a process consisting of successive
physiological phases, with different exogenous requirements. Concentrations of auxins …

In agriculture, nutrient depleted soil is a common problem, hence large amounts of applied
fertilizer are required to maintain optimal nutrient levels. Nutrient-deficient plants are often …
