I’ve decided to move from X to Bluesky, a platform that better aligns with my values and goals. Grateful for the connections here! Find me on Bluesky @DustinWolkis #GoodbyeX

🌸Paper alert🌸 Excited to share our latest work on pollen temperature tolerance (PTL) across various climates, growth forms and phylogenies! We explore the temperature limits (Tmin, Topt, Tmax) of 191 plant species critical to plant reproduction under climate change. 1/7

🎃 In the spirit of #Halloween here are some images Kou (Cordia subcordata; #Boraginaceae) fruit (drupe) stony endocarp. 🌰 Fruit are 4 locular with one #seed per locule. "Eye holes" appear as empty locules. 🌱 Kou is a canoe plant & indigenous in #Hawaiʻi.

Out now in @Botanical_'s APPS with Bruce Baldwin & @fawcett_susan; "Embryo excision in Compositae, with implications for combating biodiversity loss" 🌱We describe and illustrate a detailed method of embryo excision which can aid conservation efforts. doi.org/10.1002/aps3.11608
Embryo excision of Layia platyglossa. (A) Mature fruit from commercially available seed. (B) Indument is scraped away from the fruit wallto improve visibility of the fruit surface; one pin is used to stabilize the fruit, while the second pin pierces the fruit wall just below the ovary summit at anoblique angle revealing the embryo. (C) A strip of fruit wall is pried away from the apex towards the base. (D) Half of the fruit wall has been removed, andthe membranous seed coat is gently removed. (E) Pins are used to pry open the fruit wall to remove the embryo. (F) A mature, healthy, well‐hydratedembryo spreads its cotyledons apart shortly after the membranous seed coat is removed. Illustration by Susan Fawcett.

Today I talked about dry #seed architectures promoting fast ageing at @ibc2024. Here I presented the latest studies made by some of my former MSc and PhD students @KewScience. They made a great job that is moving seed science forward. Congrats.

🎉Congrats to @NTBG Seed Lab Intern & @willamette_u undergrad @LauleaMiike for presenting pollen research results! 💮Hōlei (Ochrosia kauaiensis; #Apocynaceae; @IUCNRedList CR) pollen germination was highest at 35% sucrose & 25-35°C. Longevity at varying MCs & temps are up next!
