Different plant species within the grasses were parallel targets of domestication, giving rise
to crops with distinct evolutionary histories and traits. Key traits that distinguish these species …

Sex chromosomes are widespread in species with separate sexes. They have evolved many
times independently and display a truly remarkable diversity. New sequencing technologies …

Changes in gene dosage can have tremendous evolutionary potential (eg whole-genome
duplications), but without compensatory mechanisms, they can also lead to gene …

Polyploidization presents an unusual challenge for species with sex chromosomes, as it can
lead to complex combinations of sex chromosomes that disrupt reproductive development …

Telomeres are essential structures formed from satellite DNA repeats at the ends of
chromosomes in most eukaryotes. Satellite DNA repeat sequences are useful markers for …

Sex chromosomes have evolved in many plant species with separate sexes. Current plant
research is shifting from examining the structure of sex chromosomes to exploring their …

Sex chromosomes in plants have been known for a century, but only recently have we
begun to understand the mechanisms behind sex determination in dioecious plants. Here …

Despite theoretical expectations of balanced 1: 1 sex ratios between females and males,
many dioecious plant species exhibit sex ratio distortions. A recent study in persimmon …

Linnaeus's very first opus, written when he was 22 years old, dealt with the analogy that
exists between plants and animals in how they 'propagate their species', and a revised …

Chromosome doubling in ornamental plants, as shown by our study in daylilies
(Hemerocallis spp.), has great potential to increase tolerance to abiotic stress. Drought is the …
