"Duke University has decided to close its herbarium, a collection of 825,000 specimens of plants, fungi and algae that was established more than a century ago. The collection, one of the largest and most diverse in the country, has helped scientists map the diversity of plant life and chronicle the impact of humans on the environment.
The university’s decision has left researchers reeling."
Women in Science: 6 Pioneers in Plant Photobiology
To celebrate the “International Day of Girls and Women in Science”, Botany One highlights six exceptional female researchers who greatly contributed to shed new light on Plant Photobiology – a scientific discipline that studies the effects of light on biological processes in green organisms.
@botanyone Of these 6, in another millennium, Joanne Chory's genetics changed the field's view of light signalling. She shared some her first #Arabidopsis mutants, which identified phytochrome input to the #circadian clock in a paper together.
Elaine Tobin's lab uncovered clock proteins with some impressive biochemistry. Hers was the first (only?) group to produce an antibody for the native protein of the first Arabidopsis clock mutant toc1. A very tough protein to work with, by all accounts.
I'm trying to find out about people & institutions working in the emerging Plant Humanities. I'd like to be able to do an informational interview with someone in this field to see if it's where I'd like to head.
What are your favorite plant, botany, or ecology podcasts? Some of mine are 'In Defense of Plants', 'The Field Guides', and 'Headwaters'. Sometimes CPBBD is great too. With the vast array of experience and backgrounds here, I bet y'all have some great suggestions that may not be limited to US white doods as hosts, I'll take more of those but I also would love more diverse recs!
@futurebird my podcast feed for CPBBD stopped working a month or two ago. I love his videos though! He in part changed the direction of my career. His impact is widespread, I think!
The share of anthropophytes in the tree stands of urban forests in Katowice (Silesian Upland, S Poland) (OA) https://botany.fyi/73uvxt
The aim of this study was to determine the share of alien species in the tree stand structure of urban forests in the city of Katowice (Upper Silesian Industrial Region). A total of 50 woody species were recorded in the analysed stands, including 31 native species and 19 of alien origin. #Botany#PlantScience
Native desert plants have the potential for phytoremediation of phytotoxic metals in urban cities: implications for cities sustainability in arid environments (OA) https://botany.fyi/qriptz
El-Keblawy et al assessed the ability of three native desert plants—Pennisetum divisum, Tetraena qatarensis, and Brassica tournefortii—to accumulate phytotoxic metals (PTMs) in their different plant organs, including leaves, stems, and roots/rhizomes. #Botany#PlantScience
European beech trees more than 1,500 kilometers apart all drop their fruit at the same time in a grand synchronization event now linked to the summer solstice. #Botany
Butterfly pollination in Platycoryne (Orchidaceae): evidence for a key pollinator shift in the large Habenaria clade (OA) https://botany.fyi/odgt8a
Johnson documents a novel case of butterfly pollination in Platycoryne, an African genus that is phylogenetically embedded in the very large Habenaria clade in the Orchidaceae. Most Habenaria species have green or white flowers and many of these have been shown to be pollinated by moths. #Botany#PlantScience
Fernández et al summarize our current knowledge of gene expression responses to sulfate deficiency and recent efforts towards the identification of the transcription factors that are involved in controlling these responses. #Botany#PlantScience
Monitoring genetic transformation with RUBY visible reporter in Nicotiana tabaccum L. ($) https://botany.fyi/6fxs13
Jogam et al transformed Nicotiana tabacum with a RUBY vector construct consisting of three gene clusters, CYP76AD1, DODA, and 5-GT, along with a hygromycin selective marker for visible reporter study. After three weeks of transformation, the betalain pigments were easily detected in the explant leaf tissue.

Cincinnati plants thousands of trees to reduce temperature in neighborhoods that are urban heat islands https://botany.fyi/4bbulk
It’s going to feel hot everywhere in the Tri-State this week, but some of Cincinnati's neighborhoods might be about 10 to 20 degrees hotter than others. #Botany
