Auxin boosts energy generation pathways to fuel pollen maturation in barley
Barley pollen autonomously produces high auxin levels to control its maturation. Auxin is required to enhance the expression of central carbon metabolism genes. Increased flux of energy production pathways fuels pollen starch accumulation
Arabidopsis DEFECTIVE KERNEL1 regulates cell wall composition and axial growth in the inflorescence stem
The plant-specific calpain, DEFECTIVE KERNEL1 (DEK1), influences primary wall growth by indirectly regulating cellulose and pectin deposition. DEK1 activity is required for the coordination of stem strengthening with elongation during axial growth.
DEFECTIVE KERNEL1 (DEK1) Regulates Cell Walls in the Leaf Epidermis
Increased levels of cellulose and pectins in epidermal cell walls of Calpain-overexpressing plants correlates with the expression of several cell wall-related genes, linking transcriptional regulation downstream of DEK1 with cellular effects.
Regulation of cell wall genes in response to DEFECTIVE KERNEL1 (DEK1)-induced cell wall changes
LTP3 and AP2TF are regulated by a feedback mechanism in response to DEK1-induced changes in the cell wall, and contribute to the phenotypes seen in plants with altered DEK1 expression.
