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.

Regulation of glucosylceramide synthase and sphingolipid remodeling in the plant response to phosphate deficiency (Bao Yang , Yan Peng , Guo Zhang , Ruifan Liu , Simin Hao , Yi Ren , Shaoping Lu , Xuemin Wang , Liang Guo) doi.org/10.1093/plce... #PlantScience

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).

☀️ 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.

TaLAC129 is a negative regulator of arbuscular mycorrhizal symbiosis but enhanced the growth and yield of bread wheat This study identifies TaLAC129, a key laccase gene, as a negative regulator of arbuscular mycorrhizal (AM) colonization in wheat. Overexpression of TaLAC129 enhances nutrient uptake efficiency and wh...

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.
