Another missing link..?

Li, Jin et al. show how #MYB factor (MYB41) is involved in the crosstalk between cell wall mannose & #brassinosteroid signalling pathways, thereby promoting lateral root development in #Mirabilis jalapa

Proposed model for MirMAN-mediated mannose regulation of lateral root development. MirMAN-mannose activates BR biosynthesis via AtMYB41, which in turn potentiates auxin signaling, ultimately working synergistically to promote root development.

Floral Friday...🪷

Mao et al show that orchid #MYB factor (PaMYB55) positively regulates cell expansion & wall integrity by promoting lignin & cellulose biosynthesis, contributing to both floral morphology & defense against pathogen spread

#PlantScience

Images showing the effects of VIGs silencing of PaMYB55 leading to a decrease in cellulose and lignin content in the peduncle. (a, b) panels show inflorescence with flowers from mock (a) and PaMYB55-VIGS (b) plants. Panels c,d, show close-ups of the peduncles shown in (a) and (b). Panels e,f, show distribution of cellulose and lignin examined by CLSM. panels g-l show close-up images of cellulose (g), lignin (h), and merged (i) signals from the boxed region in (e) of the mock peduncle. Image taken from figure 6 of Wan-Ting Mao, Wei-Han Hsu, Pei-Tzu Lin, Chang-Hsien Yang, PaMYB55 regulates cellulose and lignin deposition to control floral organ development, cell wall integrity, and pathogen resistance in Phalaenopsis orchids, Plant and Cell Physiology, Volume 67, Issue 8, August 2026, Pages 1414–1429, https://doi.org/10.1093/pcp/pcag062
