Natural Variation of COLD and CATECHINS REGULATOR 1 Coordinately Fine‐Tunes Cold Tolerance and Tea Quality in Tea Plants

open access: yesAdvanced Science, EarlyView.
Multi‐trait genome‐wide association mapping identifies a central hub regulator, COLD AND CATECHINS REGULATOR 1 (CCR1), and its excellent natural allele variation, coordinately enhancing cold tolerance and promoting catechins biosyntheis. CsCCR1 interacts with CsCBF1/3 and is transcriptionally activated by CsLUX and CsKUA1 to promote catechins ...

An Intelligent Wound Dressing Platform Based on Natural pH‐Sensors From Syzygium cumini

open access: yesJournal of Applied Polymer Science, EarlyView.
This study presents a dual‐functionality wound dressing platform based on an alginate–hyaluronate matrix integrated with Syzygium cumini extract. The smart film acts as a sensitive, reversible pH‐sensor for real‐time infection monitoring and a structural plasticizer that enhances mechanical conformability.
