Polyploidy, defined as the coexistence of three or more complete sets of chromosomes in an
organism's cells, is considered as a pivotal moving force in the evolutionary history of …

Background Biological invasions are a major ecological and socio-economic problem in
many parts of the world. Despite an explosion of research in recent decades, much remains …

This publication opens with the inevitable introduction, moves on to the present traditional
approach to breeding for yield stability, and then enumerates a detailed discussion of the …

The approach adopted in this review has been to consider nutrient elements from the
standpoint of the properties that make them essential, how they are obtained and how …

The role of polyploidy per se in the development of evolutionary novelty remains one of the
outstanding questions in flowering plant evolution. Since chromosome doubling usually is …

The four main headings to this review are: properties of the root surface (mentioning
mathematical models of nutrient uptake, root hairs, and modifications of rhizosphere nutrient …

The mechanisms which have evolved in higher plants to cope with excess sulfur in their
environments are reviewed. Survival in a sulfur-rich environment is seldom achieved …

There are many ways in which plants can adapt or respond to nutrient stress. These can be
via alterations to root branching and root extension rates, rate of uptake per unit root length …

Considerable progress has been made in crop improvement for resistance and adaptation
to mineral nutritional problems in soils. This paper discusses some of the advances made in …

A number of facts suggest that the multiplication of the genome has played an important role
in the evolution of all major phylogenetic groups (1–4). Multiplication might be achieved …
