Cell division, endoreduplication and cell expansion are key processes for plant growth and
development. Light is the main source of energy for plants and as such has a strong effect …

Background Cotton fibers provide a powerful model for studying cell differentiation and
elongation. Each cotton fiber is a singular and elongated cell derived from epidermal-layer …

Thirty years ago, we provided the first clear evidence of overcompensation, ie, increased
flower, fruit, and seed production following herbivory (Paige and Whitham, 1987; Stowe et …

Plants have numerous mechanisms to cope with the negative effects of herbivory, including
plant resistance, structural and chemical traits that reduce damage, and plant tolerance, the …

Whole-genome duplication (WGD) doubles the DNA content in the nucleus and leads to
polyploidy. In whole-organism polyploids, WGD has been implicated in adaptability and the …

In this study, we developed a model of tomato (Solanum lycopersicum L.) fruit growth
integrating cell division, cell growth and endoreduplication. The fruit was considered as a …

Endoreduplication is the phenomenon by which cells increase their ploidy.
Endoreduplication is initiated by the transition from the mitotic cell cycle to the endocycle, in …

Polyploidy after hybridization between species can lead to immediate post-zygotic isolation,
causing saltatory origin of new species. Although the incidence of polyploidization in plants …

DNA-damage tolerance (DDT) in yeast is composed of two parallel pathways and mediated
by sequential ubiquitinations of PCNA. While monoubiquitination of PCNA promotes …

Endoreduplication, the replication of the genome without mitosis, leads to endopolyploidy,
an increase in cellular chromosome number. Although endoreduplication is widespread …
