Polyploid breeding in Portulaca grandiflora L.

Bioinformatic aspects of breeding polyploid crops

Cell Suspension Cultures of Portulaca grandiflora as Potent Catalysts for Biotransformation of L-Tyrosine into L-DOPA, an Anti-Parkinson’s Drug

3,4-Dihydroxy L-phenylalanine (L-DOPA) is considered a potent drug for the treatment of Parkinson disease, a neurologic disorder. Enantiomerically pure L-DOPA is produced from L-tyrosine in a single-step biotransformation process using callus cultures of the plant Portulaca grandifloraHook (Portulacaceae). Callus cultures were induced in MS medium provided with growth regulators such as benzyla...

Captive Breeding Programs Based on Family Groups in Polyploid Sturgeons

In species with long life cycles and discontinuous availability of individuals to reproduction, implementing a long-term captive breeding program can be difficult or impossible. In such cases, managing diversity among familiar groups instead of individuals could become a suitable approach to avoid inbreeding and increase the possibility to accomplish a breeding scheme. This is the case of sever...

Characterization and functional identification of a novel plant 4,5-extradiol dioxygenase involved in betalain pigment biosynthesis in Portulaca grandiflora.

Betalains are pigments that replace anthocyanins in the majority of families of the plant order Caryophyllales. Betalamic acid is the common chromophore of betalains. The key enzyme of the betalain biosynthetic pathway is an extradiol dioxygenase that opens the cyclic ring of dihydroxy-phenylalanine (DOPA) between carbons 4 and 5, thus producing an unstable seco-DOPA that rearranges nonenzymati...

Portulaca oleracea L.: A Review of Phytochemistry and Pharmacological Effects

Portulaca oleracea L., belonging to the Portulacaceae family, is commonly known as purslane in English and Ma-Chi-Xian in Chinese. It is a warm-climate, herbaceous succulent annual plant with a cosmopolitan distribution. It is eaten extensively as a potherb and added in soups and salads around the Mediterranean and tropical Asian countries and has been used as a folk medicine in many countries....
