During meiosis, recombination between allelic sequences on pairs of homologous chromosomes forms crossovers; these crossovers help make sure that the homologs segregate accurately (reviewed in Zhang et al., 2014). However, cells must suppress recombination between non-allelic sequences, as ectopic recombination…

Ornamental grasses with a sprawling growth habit may be welcome in the garden, but grasses such as maize (Zea mays) give the highest yields when they exhibit upright leaf architecture, allowing them to be planted at high density while maximizing their exposure to sunlight. The maize leaf is composed…

A lot of effort goes into making a flower. Suites of genes must function in the right place at the right time. If not, stamens might grow where sepals should be, and so on, yielding homeotic mutant flowers. In general, flower parts are arranged in four concentric whorls of organs, including (from outside…

Isoprenoids are a huge group of compounds that include primary metabolites such as carotenoids, chlorophylls, and hormones, as well as a plethora of specialized secondary metabolites. In addition to their importance in the physiology of plants (and of other kingdoms of life), isoprenoids have drawn attention…
