S-Alk(en)ylcysteine sulfoxides (CSOs), such as methiin, alliin, and isoalliin, are health-beneficial natural products biosynthesized in the genus Allium. Here, we report the induction of multiple callus tissue lines from three Allium vegetables, o...

S-Alk(en)ylcysteine sulfoxides are sulfur-containing natural products characteristic of the genus Allium. Both the flavor and medicinal properties of Allium plants are attributed to a wide variety of sulfur-containing compounds that are generated ...

Higher plants take up sulfate and convert it to adenosine 5'-phosphosulfate (APS). APS can be a substrate of sulfur reduction, or can be phosphorylated by APS kinase to yield 3'-phosphoadenosine 5'-phosphosulfate (PAPS), a donor for...

SULTR1;1 and SULTR1;2 are two high-affinity sulfate transporters co-localizing at epidermis and cortex of Arabidopsis roots for the uptake of sulfate from the environment during sulfur limitation (-S). Previously, we have reported that -S inductio...

SULTR1;1 and SULTR1;2 are high-affinity sulfate transporters localizing at the epidermis and cortex of Arabidopsis roots. The double knockout mutant, <I>sultr1;1 sultr1;2</I>, was unable to grow on a low-sulfate medium containing 15 &a...
