Unexpected Dual Function of Plant YUCCA Enzymes Links Chlorophyll Catabolism to Auxin Homeostasis

open access: yesAngewandte Chemie, EarlyView.
YUCCA enzymes are well known to catalyze the main step of auxin biosynthesis in plants. Here, a hitherto undescribed dual function was discovered, revealing that some YUCCAs also act in chlorophyll degradation. In vitro feedback regulation furthermore suggests a link between chlorophyll degradation and hormone homeostasis and a physiological role of ...

BioCNTs Mediated Delivery of Systemically Mobile Small RNAs via Leaf Spray to Control Both Tomato DNA and RNA Viruses

open access: yesAdvanced Science, EarlyView.
A carbon nanotube‐based biopesticide system (BioCNTs) enables efficient delivery and systemic movement of RNAi molecules to control major tomato viruses. By integrating shRNA and tRNA‐like structures (TLS) with BioCNTs, this green and scalable approach achieves long‐term silencing and high antiviral efficacy through simple foliar spraying.

The stability of pigments in the thalli and extracts of the Barents Sea fucus algae

open access: yesVestnik MGTU, 2019
Fucus algae of the Barents Sea are a promising source of biologically active substances (BAS), including carotenoid and chlorophyll pigments. The main direction of processing these types of brown algae is aimed at obtaining polysaccharides, and therefore

A New Chlorophyll Degradation Pathway [PDF]

open access: yesThe Plant Cell, 2009
Chlorophyll degradation is vital during leaf senescence and fruit ripening, as it allows for recycling of nitrogen and other nutrients and for protection from buildup of phototoxic chlorophyll intermediates ([Hortensteiner, 2006][1]).

Domestication of Tartary Buckwheat Shaped a Regulatory Module for Seedling Salt Tolerance by Targeting the Magnesium Transporter Gene FtMGT2

open access: yesAdvanced Science, EarlyView.
Domestication of Tartary buckwheat is selected for a salt tolerance mechanism involving the magnesium transporter FtMGT2. Its expression is controlled by the FtAGL16‐FtMYB15L module, which is stabilized under salt stress through a competitive interaction that blocks its degradation by the E3 ligase FtBRG1, ultimately boosting Na⁺ efflux and plant ...

Characterization of phytoplankton biodiversity in tropical shipwrecks off the coast of Pernambuco, Brazil Caracterização da biodiversidade do fitoplâncton em naufrágios tropicais da costa de Pernambuco, Brasil

open access: yesActa Botânica Brasílica, 2010
The phytoplankton community was studied around two artificial reefs (shipwrecks Servemar-X and Servemar-I), located off the coast of Pernambuco, northeastern Brazil, aiming to identify and thus, better describe these environments.

Covalently linked chlorophyll a dimer: A biomimetic model of special pair chlorophyll [PDF]

open access: yesProceedings of the National Academy of Sciences, 1976
The synthesis of a covalent dimer of chlorophyll a which possesses properties strikingly similar to those exhibited by P700 special pair chlorophyll in vivo is described. The covalent dimer is characterized by several spectroscopic techniques.
