Plasmodesma 2001: on safari through the symplast.
Plant cells need to communicate with each other to orchestrate lifelong development, to integrate physiological processes, and to coordinate pathogen defense responses. The transmission of intercellular signals is an important means of regulating all plant life processes, from fertilization to senescence. In this framework, plasmodesmata (PD)— nanopores lined by plasma membrane that bridge the ...
متن کاملCriminal Victimization 2001: Changes 2000-2001 with Trends 1993-2001
Americans age 12 or older experienced approximately 24.2 million violent and property victimizations in 2001 according to the National Crime Victimization Survey (NCVS). Overall criminal victimizations included about 18.3 million property crimes (burglary, motor vehicle theft, and theft), 5.7 million violent crimes (rape, sexual assault, robbery, aggravated assault, and simple assault), and abo...
متن کاملPlasmodesma-mediated selective protein traffic between "symplasmically isolated" cells probed by a viral movement protein.
Intercellular communication is essential for differentiation and development. In plants, plasmodesmata (PD) form cytoplasmic channels for direct communication. During plant development, programmed reduction in PD number and transport capacity creates the so-called symplasmic domains. Small fluorescent dyes and ions can diffuse among cells within a domain but not across domain boundaries. Such s...

This paper discusses the difficulties of describing an appropriate notion of the security attributes caller and target in object-oriented middleware systems such as CORBA. Our analysis points out that, whilst there is no information available on the ORB layer to describe the caller and target, it is possible in practice to use descriptors from other layers. In CORBA security, the mechanism-spec...

Based on research conducted by NCBI’s comparative genomics group, the database of Clusters of Orthologous Groups of proteins (COGs) represents a phylogenetic classification of proteins encoded in complete genomes. The COGs are derived from an “all-against-all” sequence comparison of the encoded proteins. Each COG consists of individual proteins or groups of paralogs from at least three lineages...
