Game changer for cell-based plant genetics: the labs of Caixia Gao & Jin-Long Qiu have developed very efficient self-replicating vectors and they just published a very nice proof-of-concept paper.

☀️ SPECIAL ISSUE RESEARCH 🌡️

📖 Garro et al. show that non-CG DNA methylation represses SDC expression to regulate auxin & gibberellin-related genes, maintaining hypocotyl elongation in warm temps.

Fig. 7.Proposed model for the role of DNA methylation (DNAme) in the regulation of hypocotyl elongation during thermomorphogenesis in Arabidopsis. DNAme represses expression of SDC to prevent degradation of PIF4, probably by promoting GA-mediated inhibition of DELLA, thereby enhancing warm-induced auxin biosynthesis and hypocotyl growth. In addition, repression of SDC affects other aspects of auxin metabolism in a PIF4-independent manner (dashed orange line). Besides SDC repression, DNAme might also influence additional regulatory pathways to promote temperature-induced hypocotyl growth (dashed gray and black lines).

Interesting paper, but a yield trial in little flower pots does not convince me of the "agronomic" relevance of these conclusions. I find the wording of this paper quite misleading.
