Vector-borne viruses such as rice stripe virus (RSV) are transmitted from plant to plant by insects such as planthoppers. Plants under attack often emit volatile compounds such as methyl salicylate (MeSA) that attract parasitoid wasps that destroy the eggs of the virus-transmitting insects. In a recent…

In nature, plants often face multiple attackers simultaneously, giving rise to complex three-way interactions that can reshape defense outcomes in unexpected ways. An intriguing example comes from observations that prior aphid infestation, or even pretreatment with aphid honeydew, suppresses the jasmonic…

Viruses spreading to crops via tiny insects is one of agriculture’s biggest problems. Liang et al. uncovered the two-part strategy used by the tomato yellow leaf curl virus (TYLCV) to hijack the whitefly, Bemisia tabaci. It’s a double dose of manipulation designed to guarantee infection. The virus…

If you’ve ever looked closely at a tomato flower, you might have noticed that its anthers cluster together in the center of the flower, making the pollen inaccessible to most insects. Tomato flowers are an example of a buzz pollinated flower, in which the pollen is released by the physical shaking…

In the natural environment, plants are constantly attacked by animals. Plant immunity is regulated by a network of genes and hormones including salicylic acid (SA) and jasmonic acid (JA). A recent study suggests that herbivore insects threaten plants with concerns more than the bite. Han et al., found…

The long, long history of plant-pollinator interactions has led to a stunning variety of flower forms, including variations in petal color and iridescence. Color is caused by the accumulation of various pigments that selectively absorb certain wavelengths of light, whereas iridescence arises from surface…

Release of scents or volatile compounds influence pollinator preference for or localisation of many flora. In excess of 1,700 distinct floral scents have been classified to date, yet our understanding of biosynthetic processes associated with many scents is limited. Kang et al. recently determined the…

Insect-induced galls are abnormally patterned plant organs that provide insects with protection and a nutrient source, yet mechanisms underlying the development of these unique organs are mostly unknown. To identify insect factors that govern gall pattering, Korgaonkar et al. turned to the natural variation…
