Leaf clippings as protein factories

Traditionally, if researchers want to produce some proteins such as vaccinum，they need to develop a genetically modified plant first and getting government approval can take years. This new technique could induce plant leaves to mass-produce custom proteins in a matter of weeks. The plant cells could make virtually any kind of protein, including antigens for rapid production of vaccines against new viruses. Best of all, because this does not involve genetically engineering the entire plant, the approval process is expectede to be much simpler.

Transcriptomic and Proteomic Analyses of Pericycle Cells of the Maize Primary Root

Each plant cell type expresses a unique transcriptome and proteome at different stages of differentiation dependent on its developmental fate. This study compared gene expression and protein accumulation in cell-cycle-competent primary root pericycle cells of maize (Zea mays) prior to their first division and lateral root initiation. These are the only root cells that maintain the competence to divide after they leave the meristematic zone.

The red fluorescent protein eqFP611: application in subcellular localization studies in higher plants

annatto submitted, created time 1 year 6 months (www.biomedcentral.com)

"In plants, eqFP611 is a suitable fluorescent reporter protein. The unmodified protein can be expressed to levels easily detectable by epifluorescence microscopy without adverse affect on the viability of plant cells. Its subcellular localization can be manipulated by N-terminal signal sequences. eqFP611 and GFP are fully compatible in dual-labeling experiments."
