Going With the Flow: How Chemical Cues Shape Plant Strategies
Barley plants make small talk with neighbors to communicate growth and defense strategies
Lab science. Citizen science. Your source for plant science.
Announcing that the videos would start without a plan seemed like a good idea to give me a deadline to hit. Next door's gardeners were gone, giving me a clear run. What I didn't know was that another near neighbour had decided to replace their drive, which led to a lot of pneumatic drilling. This killed any chance of filming. So, by Wednesday, I was not in a sunny mood.
There's one video out this week, and the goal is to get to three a week initially. I'm not planning to link to the early ones, as they're practice and are not going to be great. They're also being written up as social media threads and then being compiled into short blog posts, which look better. Things I've learned this week include that I really don't cope well with bright light, so I might need sunglasses to film simply to avoid squinting at the camera.
I can't be sure I'll hit the target of three a week, but I can say there will be another email sharing what we've posted, as well as the stories you're sharing on Mastodon and Bluesky, and career postings at the usual time.
Until then, take care,

Travelling Far Does Not Mean Living Long for Moss Spores
A new study shows that moss spore longevity depends strongly on developmental stage and storage conditions, with important consequences for dispersal and establishment.
Night Gardeners and Sticky Bottoms: The Unlikely Mistletoe Dispersers of Madagascar
A study in the rainforests of Madagascar reveals that the primary dispersers of mistletoe are not birds, but two small nocturnal lemurs that help disperse seeds using a technique as eccentric as it is effective.
Humans Have a Profound Impact on Urban Biodiversity
Urbanization leads to a 50:50 ratio of native to non-native plant species.
Salt, Flowers and Bees
Salt stress did not change pollen or bee visitation, while the number of open flowers remained as the strongest factor to attract bees.
A familiar weed may be more diverse than we thought
The common weed Sonchus asper may actually contain several distinct evolutionary groups that can be revealed by studying both its traits and DNA.

Herbaria Meet Citizen Science (+”Weird Plant” Talk!): A Conversation with Adam Schneider - A Botanical Podcast
Herbaria are amazing libraries of plant biodiversity—they serve as time capsules of a particular time and place, but they are also so much more! Listen in on this conversation between our podcast host and Adam Schneider, associate professor at the University of Wisconsin – La Crosse, as they discuss their love of plant collections and how herbaria and iNaturalist (a social network of naturalists, citizen scientists, and biologists built on the concept of mapping and sharing observations of biodiversity across the globe) complement each other.

When aspen trees experience drought, their leaf cells change shape
The surface of an aspen leaf looks like a jigsaw puzzle under the microscope. Researchers at Umeå Plant Science Centre have now identified a gene that helps shape these interlocking cells – and discovered that both the gene's activity and the cells' shape change when the tree experiences drought.

How a desert alga helps us understand plants’ adaptability to extreme environmental conditions
A single-celled green alga from the sand dunes of the Negev Desert has, within just a few years, become a key model organism in modern photosynthesis research. Chlorella ohadii helps researchers better understand plants’ adaptability to extreme environmental conditions. These findings could help make crops more resilient to heat, drought, and other consequences of climate change in the future.

Are plant-pollinator interactions more specialised in the tropics? A new global analysis suggests that it’s complicated…
Some scientific questions have a habit of following you around for much of your career. Back in 2002, Louise Cranmer and I published a paper in the journal Oikos asking a deceptively simple question: are tropical plants more specialised in terms of their pollinators?

Three botany papers widely shared on Bluesky this past week were:
1. NO VEIN is an ancestral immunity protein involved in plant-virus interaction
Lågeide, E. et al. · bioRxiv · 2 posts · 83 likes · 48 reposts on Bluesky
Here we show that NO VEIN (NOV), a plant protein previously characterized for its essential developmental roles in Arabidopsis thaliana, shares domain composition and structural similarity with Tiamat, a bacterial antiphage protein.
Eirik Lågeide @eiriklag.bsky.social · on Bluesky
Very excited to share the first preprint from my PhD with the community! This is also the first paper from the Plant Immunogenomics group with @galofir.bsky.social, so stay tuned for more!

2. Stepwise evolution of the developmental and symbiotic functions of DELLA in land plants
Melkonian, K. et al. · New Phytologist · 2 posts · 44 likes · 33 reposts on Bluesky
In flowering plants, DELLA (named after a conserved amino acid motif containing Aspartate (D), Glutamate (E), Leucine (L), Leucine (L), and Alanine (A)) proteins are GIBBERELLIN INSENSITIVE, REPRESSOR OF GA1-3, and SCARECROW (GRAS) transcription factors and play multiple functions mediated by the plant hormone gibberellin (GA).
Katharina Melkonian @katharinamel1.bsky.social · on Bluesky
Our story on DELLA in Marchantia paleacea is now published (including few updates):

3. Divergence in wilt tolerance across the range of Mimulus guttatus in the absence of stomatal regulation
Branch, H. A. et al. · bioRxiv · 4 posts · 56 likes · 18 reposts on Bluesky
Whether phenotypes and environments predict performance under stress is central to ecology and evolution and can reveal species' vulnerability to global change. We sampled Mimulus guttatus range-wide to test whether reproductive, morphological, and physiological traits predict drought responses. Surprisingly, we find that stomatal response, a key mediator of water balance, did not change as drought intensified.
Jenn Coughlan @jenncoughlan.bsky.social · on Bluesky
I am delighted to share our new preprint, led by the amazing @stressedbranch.bsky.social! This paper was a real Herculean effort by four amazing postdocs across three labs and a small army of extremely talented undergraduates. www.biorxiv.org/content/10.6... 1/n
