Summary of "A transient expression system in soybean mesophyll protoplasts reveals the formation of cytoplasmic GmCRY1 photobody-like structures."

Soybean (Glycine max (L.) Merr.), grown for its plant oils and proteins, is one of the most important crops throughout the world. Generating stable and heritable transgenic soybeans is relatively inefficient; therefore, there is an urgent need for a simple and high-efficient transient transformation method by which to enable the investigation of gene functions in soybeans, which will facilitate the elucidation and improvement of the molecular mechanisms regulating the associated agronomic traits. We established a system of transient expression in soybean mesophyll protoplasts and obtained a high level of protoplast transfection efficiency (up to 83.5%). The subcellular activity of the protoplasts was well preserved, as demonstrated by the dynamic formation of GmCRY nucleus photobodies (NPs) and/or cytoplasmic photobody-like structures (CPs) in response to blue light. In addition, we showed that GmCRY1b CPs colocalized with GmCOP1b, a co-ortholog of Arabidopsis thaliana CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1), which provided new insight into the potential roles of GmCRY1s in the cytoplasm.

Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX). (From Adams et al., Principles of Neurology, 6th ed, pp822-3)

Method in which prolonged electrocardiographic recordings are made on a portable tape recorder (Holter-type system) or solid-state device ("real-time" system), while the patient undergoes normal daily activities. It is useful in the diagnosis and management of intermittent cardiac arrhythmias and transient myocardial ischemia.
