Throwing Shade

  • joram 

Dingdingdingding it’s a new episode of the plants and pipettes podcast! This week, Tegan brought you a paper about how plants recognise their family growing left and right of them. Joram looked at vernalisation and how it is triggered after winter when plants bolt and produce flowers. Enjoy!

Tegan’s paper: Crepy, M. A. and Casal, J. J. (2015), Photoreceptor‐mediated kin recognition in plants. New Phytol, 205: 329-338. doi:10.1111/nph.13040

Joram’s paper: Gibbs, D. J., Tedds, H. M., Labandera, A.-M., Bailey, M., White, M. D., Hartman, S., … Holdsworth, M. J. (2018). Oxygen-dependent proteolysis regulates the stability of angiosperm polycomb repressive complex 2 subunit VERNALIZATION 2Nature Communications9(1), 5438.

Tegan’s favourite plant is Ophioglossumreticulatum which has a very large genome.

The paper on pipettes inspired by plants: Nakamura, K., Hisanaga, T., Fujimoto, K., Nakajima, K., & Wada, H. (2018). Plant-inspired pipettesJournal of The Royal Society Interface15(140), 20170868.

  1. Hey, I haven’t finished this week’s podcast yet but here’s a link to a book that describes the origin of the name polycomb. https://www-sciencedirect-com.ezproxy.lib.monash.edu.au/science/article/pii/B9780128097373000015

    For those that don’t have access, ‘Polycomb (Pc) mutations were first described by Ed Lewis in 1978, and the gene was characterized as a repressor of the Drosophila homeotic genes, which are key developmental genes that determine the anterior–posterior identity of embryonic domains. The name, as usual in Drosophila, comes from a common phenotype of the mutation. In this case, the dominant phenotype of flies heterozygous for a Pc loss of function mutation is the appearance of a sex comb—a row of thick bristles usually found only on the anterior legs of male flies, on the second and sometimes third legs…’

    1. Thank you for the information! It’s always great to learn more about the origins of names and nomenclature 😊
