Review: Extending Plant Defense Theory to Seeds ($) Plants have developed multiple mechanisms to deal with the natural enemies they encounter through their life. In consequence, the Plant Defense Theory has arisen to assess how plants allocate resources to this purpose. However, much of the efforts…

With society summer conferences going online, the Plant Science Research Network has hosted a series of virtual discussions on the new Plant Science Decadal Vision 2020 - 2030. On August 26, BTI President Dr. David Stern presented on the Plant Science Decadal Vision 2020–2030, a holistic vision for…

Self-incompatibility (SI) is a mechanism  used by flowering plants to prevent self-fertilization. It is controlled by a multi-allelic S-locus that allows self/non-self-recognition between pistil and pollen. In several SI systems, when male and female S-determinants match, self pollen is recognized and…

Plant defenses against herbivore or pathogen attack involve the coordination of multiple hormone-mediated signalling networks, including the jasmonate (JA) and brassinosteroid (BR) pathways. Jasmonate is an oxylipin phytohormone that triggers the transcription of defence-related proteins and secondary…

Circadian rhythms are ubiquitous among living things. A core set of so-called clock genes and their products assemble an oscillatory network that provides a rhythm to anticipate dawn and dusk (Hsu and Harmer, 2014). The circadian clock regulates the day/night rhythms of plants and light itself has many…

During fruit ripening in tomato and other flowering plants, the seeds contained within the fruit normally become dormant. However, under certain physiological conditions, seeds can germinate within fruits, a phenomenon called vivipary. Vivipary can substantially reduce yield and product quality in vegetables,…
