Cryopreservation of pineapple (Ananas comosus) apices

, 2020
The encapsulation-dehydration and vitrification techniques were experimented for freezing apices of pineapple in vitro plantlets. Positive results were achieved using vitrification only. Optimal conditions included a 2-d preculture of apices on medium supplemented with 0.3M sucrose, loading treatment for 25 min in medium with 0.75M sucrose + 1M ...

Safety evaluation of the food enzyme papain from the latex of Carica papaya L.

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The food enzyme papain (EC 3.4.22.2) is extracted from the latex of unripe Carica papaya L. by Nagase (Europe) GmbH. It is intended to be used in six food manufacturing processes. The dietary exposure to the food enzyme–total organic solids (TOS) was estimated to be up to 1.112 mg TOS/kg body weight per day. This exposure is up to one order of

Structural determinants for red‐shifted absorption in higher‐plants Photosystem I

New Phytologist, Volume 248, Issue 5, Page 2331-2346, December 2025.
Summary Higher plants Photosystem I absorbs far‐red light, enriched under vegetation canopies, through long‐wavelength Chls to enhance photon capture. Far‐red absorption originates from Chl pairs within the Lhca3 and Lhca4 subunits of the LHCI antenna, known as the ‘red cluster’, including Chls a603 and a609.
