Fig. 1 (shortened, full legend in paper): Domain architecture and phylogenetic relationships of PHR1 and its homologues across plant species. (A) Schematic representation of AtPHR1 domain structure. The domain organization of Arabidopsis thaliana PHR1 (AtPHR1) is depicted, highlighting the myeloblastosis (MYB) DNA-binding domain and the MYB–coiled-coil (CC) domain. (B) Phylogenetic analysis of PHR1 homologues in diverse plant species. Evolutionary relationships among PHR1-like proteins from Solanum lycopersicum, Oryza sativa, Zea mays, Arabidopsis thaliana, and Chlamydomonas reinhardtii were inferred based on predicted protein sequences. The Arabidopsis PHR1 protein (Gene ID: AT4G28610) was used as a query to identify homologues in the selected species. Sequence alignment was performed using MAFFT v7.475 (https://mafft.cbrc.jp) and the phylogenetic tree was constructed using the Neighbor-joining method with 1000 bootstrap replicates.

🌱🧬 REVIEW 🧬🌱

PHR proteins, classically characterized for their role in the phosphorus starvation response in plants, have also acquired new roles. The genetic and molecular basis of their functional diversity is discussed here - Mangalakkadan et al.

Spikes of blue flowers

Eleven years ago today 🌿

Muscari botryoides, the nonnative Grape Hyacinth, blooming in the Chautauqua

This year marks 80 years since the protologue [initial description] of Ukrainian endemic birch species Betula borythenica Klokov was published, and 100 years since its type specimen was collected.

This sounds great but does it work on organisms other than humans?

(Human genomes are almost identical to each other, while species with a longer evolutionary history, such as most wild species and especially plants, have much more diverse genomes.)

Happy to share our new review mapping the journey of anthocyanin research and highlighting where it is heading next!
The explosion of publications in the last decade says it all 📈
Definitely a space to watch👀 And we're here for it!✌

A collage showing on the left a picture of the bright pink closed flowers and bracts of the plant Pogonopus speciosus. On the right a scheme depicting the reaction of tryptamine and secologanic acid to vincosidic acid that is catalyzed by P. speciosus Epi-STR, an unusual R-stereoselective ortholog of strictosidine synthase.

Our funky R-stereoselective Epi-STR is now available online and open access at its permanent home @angewandtechemie.bsky.social. 🥳
This is Clara's first first-author paper, makes me extra happy!

Borage plant blue flowers, fine hairs on the flower boats and leaves stands silhouette and evening light. A vision

Most gardens are designed to look right.

This one wasn’t.

We left space — not for decoration, but for life.

It looked messy.
That’s where everything was living.

If you leave space, things arrive.

Purple Haze When the redbuds bloom

Redbud trees are spectacular early-flowering trees in the Bluegrass and much of the Eastern Deciduous Forest. They beautiful, and also have some complex flowering behavior that I don't fully understand. Have a look at the story (open to everyone).

Looking up at some spring flowers in the garden in the sunshine. Some daffodils, and some blue/ mauve flowers that look like poppies/anemones. Set against some pale leaves on the trees behind them, together with some pale blue sky and fluffy clouds behind those.

Spring time #BloomScrolling

Photo of a large cluster of deep pink sheep laurel flowers. Each flower(of perhaps 100+ in the photo) looks like a tiny parasol. Most of the photo is pink (the flowers) with small amount of green leaves (long, thin) showing through.

Photo from 2 summers ago. Each flower is about 1cm in diameter. #flower #wildflower #plants #botany

Fig. 1.Germination dynamics of freshly harvested Arabidopsis Col-0, the tcp8.1 mutant, and 35S:TCP8-overexpression (OE) seeds. Seeds were imbibed at 20 °C in darkness. (A) Percentage germination with time and (B) final germination after 7 d. Data are means (±SE), n=12–24. Significant differences were determined using one-way ANOVA followed by Tukey’s HSD tests: ***P<0.001; ****P<0.0001.

The Class-I TCP transcription factor TCP8 is a negative regulator of seed germination in Arabidopsis that counteracts the function of its close homologue TCP14 - Tian et al.

After reading a lot of the Claude Code base that was leaked taught me two things

1. I have never been more reassured than I am now. Software Developers will be around for a long time.

2. Claude Code has a hidden command to hide that a contribution was made by a Claude employee
