Photosystem II Peripheral Accessory Chlorophyll Mutants in Chlamydomonas reinhardtii. Biochemical Characterization and Sensitivity to Photo-Inhibition [PDF]

, 2001
In addition to the four chlorophylls (Chls) involved in primary charge separation, the photosystem II (PSII) reaction center polypeptides, D1 and D2, coordinate a pair of symmetry-related, peripheral accessory Chls.

Tobamoviruses CP Proteins Hijack Light‐Induced Protein (NbLIP1) to Promote Viral Replication by Facilitating VRO Formation

Plant Biotechnology Journal, EarlyView.
ABSTRACT Tobamoviruses establish viral replication organelles (VROs) on the host endoplasmic reticulum (ER) for their replication, a process demanding substantial different types of lipids. However, how viruses efficiently transfer these lipids from other compartments like chloroplasts remains incompletely understood.

An optimized protocol for the preparation of oxygen-evolving thylakoid membranes from Cyclotella meneghiniana provides a tool for the investigation of diatom plastidic electron transport

BMC Plant Biology, 2017
Background The preparation of functional thylakoid membranes from diatoms with a silica cell wall is still a largely unsolved challenge. Therefore, an optimized protocol for the isolation of oxygen evolving thylakoid membranes of the centric diatom ...

Proteomic analysis of the pyrenoid-traversing membranes of Chlamydomonas reinhardtii reveals novel components. [PDF]

New Phytol
Summary Pyrenoids are algal CO2‐fixing organelles that mediate approximately one‐third of global carbon fixation. Most pyrenoids are traversed by membranes that are thought to supply them with concentrated CO2. Despite the critical nature of these membranes for pyrenoid function, they are poorly understood, with few protein components known in any ...

Plastid Engineering for Photosynthesis‐Driven Synthesis of Hyaluronic Acid in Tobacco

Plant Biotechnology Journal, EarlyView.
ABSTRACT Hyaluronic acid (HA) is a glycosaminoglycan composed of alternating units of N‐acetylglucosamine and glucuronic acid. High moisture retention, viscoelasticity and biocompatibility are unique features that make HA polymers attractive compounds for medical applications and aesthetic purposes.

OsFeSOD3 Functions as an Enzymatic Component of the PEP Complex, Bifunctionally Regulating Chloroplastic ROS Metabolism and Chloroplast Biogenesis in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Chloroplasts are essential organelles responsible for photosynthesis, providing energy and metabolic intermediates required for plant growth and productivity. Chloroplast development is highly sensitive to environmental stresses such as drought, and this sensitivity is closely associated with growth inhibition and yield reduction under stress ...

Photosystems activities and polypeptide composition of Cyamopsis tetragonoloba and Vigna mungo thylakoids as affected by exclusion of solar UV radiation

Biologia Plantarum, 2010
The impacts of solar UV (280-400 nm) radiation on photosynthetic activities and polypeptide composition of thylakoids of cluster bean (Cyamopsis tetragonoloba L, UV-B sensitive) and black gram (Vigna mungo L., UV-B resistant) plants were compared.

A Novel Dual‐Target Compound Designed With Potent Herbicidal and Fungicidal Activity Inspired by Conserved Phytoene Synthase Domains

Plant Biotechnology Journal, EarlyView.
ABSTRACT The development of dual‐target inhibitors represents a cost‐effective strategy for integrated pest management. Here, we report the first dual‐target inhibitors designed against the evolutionarily conserved domain of phytoene synthase (PSY), a key enzyme in carotenoid biosynthesis.
