The Cell Differentiation of Idioblast Myrosin Cells: Similarities With Vascular and Guard Cells

Shirakawa, Makoto; Tanida, Mai; Ito, Toshiro (Frontiers Media, 2022-01-10)

Idioblasts are defined by abnormal shapes, sizes, and contents that are different from neighboring cells. Myrosin cells are Brassicales-specific idioblasts and accumulate a large amount of thioglucoside glucohydrolases ...
Penaeus monodon Interferon Regulatory Factor (PmIRF) Activates IFNs and Antimicrobial Peptide Expression via a STING-Dependent DNA Sensing Pathway

Soponpong, Suthinee; Amparyup, Piti; Kawai, Taro; Tassanakajon, Anchalee (Frontiers Media, 2022-01-10)
