Researchers have used silk derived from ordinary silkworm cocoons, like those seen here, mixed with bacteria and nutrients, to make a coating for seeds that can help them germinate and grow even in salty soil.

Coated seeds may enable agriculture on marginal lands

A specialized silk covering could protect seeds from salinity while also providing fertilizer-generating microbes.

MIT engineers have developed a way to deliver genes to the chloroplasts of plant cells. In these images, mesophyll cells (right) and epidermal cells (left) in an arugula leaf have been engineered to express a yellow fluorescent protein in their chloroplasts. Cell walls are stained red and chloroplasts are stained blue.

An easier way to engineer plants

MIT-led team uses nanoparticles to deliver genes into plant chloroplasts.

The toughness of Sporopollenin, a polymer within the shells of pollen grains (seen here magnified 500X using a scanning electron microscope), has made it possible for plant life to survive on land — but has also frustrated attempts to study its fundamental composition, until now.

Cracking a tough case

Whitehead Institute and MIT researchers uncover the detailed molecular structure of the sporopollenin polymer, an inert material key for the emergence of land plants.

Illumination of a book (“Paradise Lost,” by John Milton) with the nanobionic light-emitting plants (two 3.5-week-old watercress plants). The book and the light-emitting watercress plants were placed in front of a reflective paper to increase the influence from the light emitting plants to the book pages.

Engineers create plants that glow

Illumination from nanobionic plants might one day replace some electrical lighting.
