Size control of multicellular organisms poses a longstanding biological question that has
always fascinated scientists. Currently the question is far from being resolved because of the …

When subjected to abiotic stresses, plants actively re-program their growth by modulating
both cell division and cell expansion. Growth decreases rapidly upon stress onset but it …

Cytokinins are hormones that regulate cell division and development. As a result of a lack of
specific mutants and biochemical tools, it has not been possible to study the consequences …

Highlights•Cytokinins regulate cell proliferation, affecting mitosis and endoreplication.•
Cytokinins control the cell cycle both at the G 1/S and G 2/M transitions.•Cytokinins have …

Upon disturbance of their function by stress, mitochondria can signal to the nucleus to steer
the expression of responsive genes. This mitochondria-to-nucleus communication is often …

Cell proliferation is an important determinant of plant form, but little is known about how
developmental programs control cell division. Here, we describe the role of microRNA …

Brassinosteroids (BRs) play crucial roles in plant growth and development. Previous studies
have shown that BRs promote cell elongation in vegetative organs in several plant species …

Cell cycle regulation is of pivotal importance for plant growth and development. Although
plant cell division shares basic mechanisms with all eukaryotes, plants have evolved novel …

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 …

Drought is the most important crop yield-limiting factor, and detailed knowledge of its impact
on plant growth regulation is crucial. The maize (Zea mays) leaf growth zone offers unique …
