The chloroplast houses photosynthesis in all green plants, and is therefore of fundamental importance to the viability and productivity of plants, ecosystems, and agriculture. Chloroplasts are, however, extremely vulnerable to environmental stress, on account of the inherent volatility of oxygenic photosynthesis. To counteract this sensitivity, sophisticated systems of chloroplast stress acclimation have evolved, and many of these involve broad proteome changes. Here, we provide an overview of the interlocking and mutually dependent mechanisms of abiotic stress-induced chloroplast proteome remodelling. Topics that are covered in this context include: nucleus to chloroplast signalling mechanisms, with a particular emphasis on the nuclear control of the chloroplast genome; chloroplast to nucleus signalling; and the roles of chloroplast pre-protein import regulation and chloroplast proteases.

Although the roles of many DEAD-box RNA helicases (RHs) have been determined in the nucleus as well as in cytoplasm during stress responses, the importance of chloroplast-targeted DEAD-box RHs in stre...
The hyperphosphorylated nucleotides guanosine pentaphosphate and tetraphosphate (together referred to as (p)ppGpp, or magic spot) orchestrate a signalling cascade in bacteria that controls growth unde...
Aucubin, the predominant component of Eucommia ulmoides Oliv., plays an indispensable role in regulating oxidative stress. Considering that oxidative stress has previously been demonstrated to contrib...
Heat shock is one of the major abiotic factors that causes severe retardation in plant growth and development. To dissect the principal effects of hyperthermia on chloroplast gene expression, we studi...
Plant health and development are directly depending on a plant's ability to react to a constantly changing environment. Sensing of water and nutrition levels and of the biotic environment is vital for...

The current study analyses the LV geometry of failing LVs measured by MRI scanning with respect to systolic versus diastolic function. A new surgical method for remodelling enlarged left v...
Asthma is a chronic, inflammatory disease of the lung characterized by intermittent airway obstruction, airway hyperresponsiveness, presence of activated inflammatory cells, inflammatory m...
The onset and course of heart failure (HF) is triggered by a complex regulatory network that includes stressors (pressure overload by individual anatomic hemodynamic settings), intrinsic (...
The clinical relevance of the observed stress induced hyperglycemia in trauma patients remains unclear. The earlier studies suggested the implications of cytokines in stress induced hyperg...
Those nucleic acid sequences that function as units of heredity which are located within the CHLOROPLAST DNA.
Blue-light receptors that regulate a range of physiological responses in PLANTS. Examples include: PHOTOTROPISM, light-induced stomatal opening, and CHLOROPLAST movements in response to changes in light intensity.
Proteins encoded by the CHLOROPLAST GENOME or proteins encoded by the nuclear genome that are imported to and resident in the CHOROPLASTS.
The protein complement of an organism coded for by its genome.
A class of traumatic stress disorders that is characterized by the significant dissociative states seen immediately after overwhelming trauma. By definition it cannot last longer than 1 month, if it persists, a diagnosis of post-traumatic stress disorder (STRESS DISORDERS, POST-TRAUMATIC) is more appropriate.

Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
