Stressful conditions for plants can originate from numerous physical, chemical and
biological factors, and plants have developed a plethora of survival strategies including …

An analysis of over 10 000 plant genome sizes (GSs) indicates that most species have
smaller genomes than expected given the incidence of polyploidy in their ancestries …

Polyploidy is a pervasive and recurring phenomenon across the tree of life, which occurred
at variable time scales, ecological amplitudes and cell types, and is especially prominent in …

Polyploidy, or whole genome duplication, is recognized as an important feature of eukaryotic
genome evolution. Among eukaryotes, polyploidy has probably had the largest evolutionary …

Eukaryotic chromosomes occupy distinct territories within interphase nuclei. The
arrangement of chromosome territories (CTs) is important for replication, transcription, repair …

Background Stresses exert evolutionary pressures on all organisms, which have developed
sophisticated responses to cope and survive. These responses involve cellular physiology …

Whole-genome duplication resulting from polyploidy is ubiquitous in the evolutionary history
of plant species. Yet, polyploids must overcome the meiotic challenge of pairing …

Environmental constraints that include abiotic stress factors such as salt, drought, cold and
extreme temperatures severely limit crop productivity. Improvement of crop plants with traits …

Angiosperm genomes show tremendous variability in genome size and chromosome
number. Nevertheless, comparative genetic mapping has revealed genome collinearity of …

The basic unit of chromatin, the nucleosome, is an octamer of four core histone proteins
(H2A, H2B, H3, and H4) and serves as a fundamental regulatory unit in all DNA-templated …
