From recognition to response: integrated signaling pathways determining pollen acceptance and rejection in Brassicaceae

New Phytologist, Volume 250, Issue 2, Page 788-798, April 2026.
Summary Generation of competent offspring is vital for the prosperity of flowering plants. The pistil not only functions as a conduit for pollen tubes to grow to the ovary but also provides a selective venue for facilitating the growth of compatible pollen tubes and discouraging invaders and incompatible pollen.

5-Methyltryptophan Resistant Cells of Catharanthus roseus

Zeitschrift für Naturforschung C, 1979
Several cell lines resistant to 5-methyltryptophan were selected from wild type cells of different Catharanthus roseus suspension cultures. The resistant cells had up to 30 times tne normal levels of free tryptophan. Despite the increased pool size of tryptophan anthranilate synthetase activity of resistant cells was as sensitive to inhibition by ʟ ...

Engineering of the Flavone Rutinoside Biosynthetic Pathway Enables Production of Diosmin, a Venoactive Compound in Solanum lycopersicum and Nicotiana tabacum

Plant Biotechnology Journal, Volume 24, Issue 4, Page 1936-1949, April 2026.
ABSTRACT Diosmin is often used as a dietary supplement, and it is sometimes used to make phlebotropic drugs for venous diseases. Traditionally, diosmin is obtained by the dehydrogenation of the flavanone glycoside hesperidin through chemical semisynthesis.
