Medicinal plants, which the majority of people use to some degree for their health needs, provide a platform for engaging students in scientific inquiry. Straus & Chudler present an overview of online teaching resources focused on medicinal plants and ethnobotany. The sites highlighted provide a…

For decades, scientists have debated the origin of the strange patterns of grass growth known as fairy circles in the Namibian desert. Photographs show a strikingly regular pattern circles of bare ground surrounded by a ring of grass. One hypothesis is that these patterns form due to the action of insects;…

The rice brown plant hopper (BPH) Nilaparvata lugens is a damaging herbivorous insect that sucks nutrients from phloem.  Previously, Ji et al. surveyed genes encoding putative secreted proteins from the BPH salivary gland and identified NlEIG1 as a putative endo-β-1,4-glucanase (cell-wall degrading…

Climate change could affect agricultural productivity by increasing the number of days with temperatures above 30°C that staple crops like soybean, maize and wheat will experience during a given growing season. Schauberger et al. used nine statistical models to assess future threats to US crops. They…

They say that “chacun à son gout” (each has his own taste), but when it comes to tomatoes there is near universal agreement that they don’t taste as good as they used to: a fact that is borne out by gas chromatography-mass spectrometry and the panel of taste-testers employed by Tieman et al. in…

Jatropha curcas is a perennial woody plant with high seed oil content that has potential to be used in biofuel production.  However, there is limited knowledge about the biology of seed oil production in Jatropha spp.  Sun. et al., used a genetic approach to identify a J. curcas QTL that controls seed…

Sexual reproduction, with all that recombination and independent assortment, is an excellent way to generate genetic diversity and increase the likelihood that some progeny will survive. However, the seed industry strives to produce genetically uniform seeds. Although there are various ways to circumvent…

Autophagy is the process by which macromolecules and organelles are recycled. Previously it was shown that during leaf senescence or energy starvation, chloroplasts are degraded piecemeal by autophagy. In this work, Izumi et al. examined the role of autophagy in UVB damaged chloroplasts, using wild-type…
