Abstract:
... Simplex and multiplex RT-qPCR assays were developed for Alopecurus myosuroides partitivirus 1 (AMPV1), Alopecurus myosuroides partitivirus 2 (AMPV2) and Alopecurus myosuroides varicosavirus 1 (AMVV1), and compared to the existing conventional PCR assays. All assays had a high specificity and their sensitivity was increased compared to the conventional RT-PCR assays. As viral quantification is an i ...

Abstract:
... The membranes of plant cells serve diverse physiological roles, which are defined largely by the localized and dynamic recruitment of proteins. Signaling lipids, such as phosphoinositides, can aid protein recruitment to the plasma membrane via specific recognition of their head groups and influence vesicular trafficking, cytoskeletal dynamics and other processes, with ramifications for plant tissu ...

Abstract:
... Plant tissues and organs are composed of functionally discrete cell types that are all defined by the same genome sequence. Cell-type variation in part arises from differential accessibility of cis-regulatory elements that encode the blueprints for transcriptional programs underlying cell identity and function. Owing to technical limitations, the role of cis-regulatory elements in cell identity ma ...
