The cosmetic industry uses a lot of different chemicals to produce the seven or so skin care products used by the average American every day. Efforts are underway to develop renewable sources for some of these. Derikvand et al. review the chemistry and potential applications behind compounds used by…

IN BRIEF by Jennifer Lockhart [email protected] The interior of a plant cell is supported by the actin cytoskeleton, a complex network of yarn-like fibers whose form changes as the cell develops, grows, and divides. Actin fibers readily come apart (sever) and join back together, depending on the…

Eucalypts are fast-growing trees increasingly exploited for pulp, paper, bioenergy and other wood-based products. Using genetics tools and a network-based data integration (NBDI) approach, Mizrachi et al. explore a segregating Eucalyptus hybrid population for genes and pathways underlying biomass / bioenergy…

One of the many ways that Xanthomonas bacteria manipulate their host plants is by the production of transcription activator-like (TAL) effectors, which the bacterium introduces into the host cell where they alter gene expression in the host nucleus. Schwartz et al. investigated the targets of the TAL…

Root-knot nematodes including Meloidogyne javanica are major agricultural pests. Previous studies have shown that biocontrol agents including species of the fungal genus Trichoderma interfere with root-knot nematode pathogenicity, directly through effects on the nematode, and indirectly through a stimulation…

One of the big challenges of working with wheat, as compared to rice, is that the wheat we eat is polyploid; bread wheat (Triticum aestivum) is hexaploid (six copies of each gene) and pasta wheat (Triticum turgidum) is tetraploid (four copies each). Polyploidy makes forward genetics difficult; knocking…

Cultivation of Tulipa gesneriana (tulip), an economically important species due to its ornamental value, can be affected by warming winters, leading to low quality flowers produced out of season. Leeggangers et al. have sequenced RNA and used top-down and bottom-up approaches in tulips grown in two contrasting…

Where do flowers come from? Their sudden appearance and rapid radiation was described as an “abominable mystery” by Charles Darwin. Ruelens et al. examine the genetic toolkit that underpins reproductive organ formation in gymnosperms to uncover the origins of flowers (which they pragmatically describe…
