Identification of Plastoglobules as a Site of Carotenoid Cleavage

Frontiers in Plant Science, 2016
Carotenoids play an essential role in light harvesting and protection from excess light. During chloroplast senescence carotenoids are released from their binding proteins and are eventually metabolized.

Regulation of chloroplast development and function by cytokinin.

Journal of Experimental Botany, 2015
A role of the plant hormone cytokinin in regulating the development and activity of chloroplasts was described soon after its discovery as a plant growth regulator more than 50 years ago. Its promoting action on chloroplast ultrastructure and chlorophyll

5‐thiohistidine N‐acetyltransferase from Proteiniphilum saccharofermentans

ChemBioChem, Accepted Article.
Ovothiol A is a 5‐thiohistidine derivative biosynthesized by a broad range of prokaryotic and eukaryotic organisms. Its redox‐active mercaptoimidazole side chain is believed to protect cells from oxidative stress. The three enzymes that produce ovothiol A from histidine, cysteine, and S‐adenosyl methionine have been identified and characterized.

Light Deprivation-Induced Inhibition of Chloroplast Biogenesis Does Not Arrest Embryo Morphogenesis But Strongly Reduces the Accumulation of Storage Reserves during Embryo Maturation in Arabidopsis

Frontiers in Plant Science, 2017
The chloroplast is one of the most important organelles found exclusively in plant and algal cells. Previous reports indicated that the chloroplast is involved in plant embryogenesis, but the role of the organelle during embryo morphogenesis and ...

AtPHT4;4 is a chloroplast-localized ascorbate transporter in Arabidopsis

Nature Communications, 2015
Ascorbate is an antioxidant and coenzyme for various metabolic reactions in vivo. In plant chloroplasts, high ascorbate levels are required to overcome photoinhibition caused by strong light.

Redesigning a One‐Phase Enzymatic Assay to Streamline High‐Throughput Screening of Phytoene Desaturase Inhibitors

ChemFoodChem, EarlyView.
A one‐phase in vitro PDS enzyme activity assay is designed as a simple and efficient method, enabling the enhancement of substrate‐enzyme interaction and the elimination of the adverse effects of organic solvents on enzyme activity. It provides a rapid and direct evaluation method for high‐throughput screening of potent PDS inhibitors instead of using ...

Engineered chloroplast dsRNA silences cytochrome p450 monooxygenase, V‐ATPase and chitin synthase genes in the insect gut and disrupts Helicoverpa armigera larval development and pupation

Plant Biotechnology Journal, 2015
Summary In the past two decades, chloroplast genetic engineering has been advanced to achieve high‐level protein accumulation but not for down‐regulation of targeted genes.

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

Cytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.
