A naturally epigenetic gene variant, which carries hypermethylated cytosines at promoter of OsAK1 (Os08g01770), was identified in rice. The hypermethylation causes silencing of this gene and leads to albino in young leaf and panicle, shedding light on significant roles of DNA methylation on rice development.

Plants are sessile organisms that respond to invading microbes with a swift immune response. Plants carry immune receptors, which immediately activate phosphoinositide-specific phospholipase C (PI-PLC) enzymes upon their activation. We present a model in which PI-PLCs mediate the hydrolysis of essential signaling phospholipids, thereby simultaneously generating the second messengers required for a swift cellular defense response.

Wild tobacco flowers rhythmically open, emit scent and move vertically through a 140° arc. Flower position dramatically influenced cross-pollination success and seed set with nocturnal hawkmoths. By waving their flowers, this plant engages in a botanical version of synchronized dancing with its pollinators and filters its partners in this dance.

Reduced representation genome sequencing reveals patterns of genetic diversity and selection in apple

Reduced representation genome sequencing reveals that a variety of horticultural traits, such as fruit quality, tree growth habit, and resistance to biotic stress, have probably undergone selection during apple domestication.

Functional specialization of Nicotiana attenuata phytochromes in leaf development and flowering time

To understand how a wild tobacco species perceives light, we examined transgenic plants impaired in their ability to “see” particular wavelengths of light by silencing the expression of photoreceptor proteins, the phytochromes. The phytochromes were specialized in their function: B1 controlled leaf development while B2 controlled flower development.
