Very nice work by postdoc @cbuckley.bsky.social. He used transient seedling transformation of luciferase reporters to measure #circadian rhythms in ~300 Arabidopis accessions. And it worked really well…

🥬🕐 RESEARCH 🕐🥬 Most cultivated lettuce varieties have a 27 h internal clock but are grown under 24 h light cycles. Anton-Sales et al. confirm circadian resonance effects in a crop species and demonstrate yield increases of 11–29% 🥬📈 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪
Fig. 3.Visual tipburn severity scale used for lettuce phenotyping. Representative photographs of lettuce plants illustrating the six-point tipburn scoring scale, ranging from 0 (no tipburn symptoms) to 5 (severe tipburn with extensive necrosis of inner leaves). Score 0 indicates healthy plants with no visible damage; scores 1–2 reflect early-stage symptoms with minor marginal browning on young leaves; scores 3–5 represent progressive necrosis affecting an increasing proportion of the inner canopy and considered unmarketable (severe tipburn). Scale bar=10 cm.

A fascinating review. Thoughtful analysis. Much to discuss. Should ABA be reverted to dormin? My only big disagreement is that the author does not consider ion channels as potential receptors. Comparison to other kingdoms shows that ion channels can be hormone receptors. Great for journal clubs
