Transient gene expression is a powerful tool for plant genomics studies. Recently, the use of nanomaterials has drawn great interest. Delivery with mesoporous silica nanoparticles (MSNs) has many advantages. We used surface-functionalized MSNs to deliver and express foreign DNA in Arabidopsis thaliana root cells without the aid of particle bombardment. Gene expression was detected in the epidermis layer and in the more inner cortex and endodermis root tissues. This method is superior to the conventional gene-gun method to deliver DNA, which delivers the gene to the epidermis layer only. Less DNA is needed for the MSN method. Our system is the first use of nanoparticles to deliver DNA to plants with good efficiency and without external aids. MSNs, with multifunctionality and the capability of cargo delivery to plant cells as we demonstrated, provide a versatile system for biomolecule delivery, organelle targeting, and even agriculture, such as improved nutrient uptake.

A system and method to multicast guaranteed and best-effort traffic in a communications network are disclosed. According to one embodiment, incoming traffic is separated into unicast traffic and multicast traffic. Each root cell of the multicast traffic is classified based on multiple corresponding classes of service. Each root cell is then stored into a root cell buffer of multiple root cell buffers within an egress memory, each root cell buffer being associated with a corresponding class of service. According to one embodiment, each root cell is retrieved from the corresponding root cell buffer within the egress memory according to the associated class of service. Each root cell is then stored in a corresponding replication queue of multiple replication queues based on its associated class of service, with predetermined replication parameters assigned to each replication queue. Each root cell is subsequently replicated according to one or more associated replication parameters to obtain multiple leaf cells for each replicated root cell. According to one embodiment, the unicast traffic is multiplexed with the replicated leaf cells of the multicast traffic to obtain egress arrival cells. Each egress arrival cell is then stored hierarchically into a queuing buffer of multiple queuing buffers within a queuing memory according to queuing parameters corresponding to each egress arrival cell.

The present invention provides systems and methods for generating clonal root lines, clonal root cell lines, clonal plant cell lines, and clonal plants and for expressing gene products in such cell lines and plants. According to certain of the inventive methods, a viral vector containing a polynucleotide of interest operably linked to a promoter is introduced into a plant or portion thereof. Plant material (e.g., leaf portions) containing the viral vector are used to generate clonal root lines, e.g., by contacting them with A. rhizogenes so as to form hairy roots. The hairy roots are derived from single ancestral cells and are therefore clonal. These clonal root lines contain the viral vector and express the polynucleotide of interest. Clonal root cell lines, clonal plant cell lines, and clonal plants are obtained from the clonal roots. According to certain other inventive methods, a viral vector containing a polynucleotide of interest operably linked to a promoter is introduced into cells of a plant cell line (e.g., pre-existing or newly derived) that is maintained in culture. Clonal plant cell lines that express the polynucleotide of interest are obtained, e.g., by successive rounds of enrichment until a population of cells exhibiting stable expression is obtained. Clonal plants whose cells contain the viral vector are obtained from the clonal plant cell lines using standard methods. The invention provides clonal root lines, clonal root cell lines, clonal plant cell lines, and clonal plants generated using the inventive methods.
