Radiation-induced appearance of phytochrome in soybean cell suspensions.

abstract：MAIN CONCLUSION:Phytosterol homeostasis may be maintained in leaves through diversion of intermediates into glycoalkaloid biosynthesis, whereas in tuber flesh, excess intermediates are catalyzed by tuber-specific StLAS - like , resulting in low tuber glycoalkaloids. Lanosterol synthase (LAS) and cycloartenol synthase (...
