Inter‐Caste Comparison Reveals a Unique Bioenergetic Signature in Long‐Lived Ant Queens Open
Within the same species of eusocial insects, individuals of different castes typically display widely different life‐history traits: sterile workers live for a few months, while queens can live for decades. Ageing theories emphasise the im…

Rice JASMONIC ACID OXIDASES control resting jasmonate metabolism to promote growth and repress basal immune responses Open
Catabolic conversions within the jasmonate pathway have substantial consequences on phytohormone signaling output. In dicots, the jasmonic acid oxidase (JAO) catabolic route leads to jasmonic acid (JA) hydroxylation, which limits its conju…
