Because much of the genetic diversity of our crops plants was lost during domestication, many breeding efforts endeavor to cross in resilience genes from wild relatives. An alternative approach is to rapidly domesticate those wild relatives themselves, for example by editing genes that affect flowering time, seed shattering, or fruit or seed size. In this […]
New technologies, like personal computers or smart phones, often have limited adoption due to their high cost or requirement for advanced technological skills. Greater affordability and ease of use leads to greater adoption. Here, Yu, Sussman et al. describe the development of an affordable, portable plant phenotyping platform and pipeline that is easy to build […]
Review. Revisiting plant electric signaling: Challenging an old phenomenon with new discoveries In the electrifying world of plant signaling, a paradigm shift is underway as researchers dig into the intricate mechanisms of action potentials (APs) and slow wave potentials (SWPs). Departing from conventional neurophysiological dogma in the animal kingdom, this review by Barbosa-Caro and Wudick […]
A review of the past 50 years of plant immunity by Jones, Staskawicz, and Dangl? Yes please! I particularly enjoy historical perspectives of a discipline, as they frame conceptual breakthroughs with the benefit of hindsight. As the article lays out, understanding the plant immune system benefitted greatly from the early advances in plant molecular biology […]
Widely and abundantly eaten tomatoes (Solanum lycopersicum) are delicious and nutritious, but the genetic diversity of cultivated tomatoes is quite narrow. In this review, Wang et al. give an overview of efforts to increase diversity, through introduction of genes from wild relatives and other approaches. Since the first tomato sequence was completed in 2012, countless […]
Low-resolution data can provide broad strokes but miss the details that come from greater information density. When striving to understand the multimillion-year evolutionary history of the angiosperms, more data certainly helps. Here, by focusing on a subset of 353 genes, Zuntini and Carruthers et al. present a phylogenomic tree that increases the number of represented […]
ATG8 is a well-characterized protein involved in autophagy that binds to the double-membrane enclosed phagophore. In a new preprint, Julian et al. explore their finding that ATG8 binds to the single-membrane enclosed vacuolar membrane (tonoplast). They observed that this binding is enhanced by treatments that weaken the cell wall, such as inhibition of cellulose synthase. […]
Cannabis sativa, also known as hemp or marijuana, is a widely cultivated plant for a variety of reasons. It is perhaps best known as a producer of an intoxicating chemical, THC, produced by glandular trichomes on female flowers, but low-THC producers (hemp) are cultivated for fibers. Flowering time affects both THC and fiber production, and […]
Review: The plant immune system: From discovery to deployment A review of the past 50 years of plant immunity by Jones, Staskawicz, and Dangl? Yes please! I particularly enjoy historical perspectives of a discipline, as they frame conceptual breakthroughs with the benefit of hindsight. As the article lays out, understanding the plant immune system benefitted […]
