Fundo Simplástico transporte de macromoléculas através de conexões intercelulares de plantas, o plasmodesmos, é de interesse para muitos fitopatologistas e biólogos. Por exemplo, várias proteínas virais são conhecidas para regular os limites de exclusão plasmodesmal tamanho para permitir o movimento viral 1-3. Além disso, algumas proteínas endógenas, entre eles importantes reguladores do desenvolvimento, são assumidos para se deslocar de célula para célula, presumive...

A chave para o sucesso do ensaio de transporte simplástico é a obtenção de alta eficiência de transformação, que permite a produção de aglomerados de sinal estatisticamente significativo e facilmente detectável. Isto pode ser conseguido usando as folhas colhidas de plantas saudáveis ​​e robustas, e preparar partículas de ouro revestidas por uma preparação de DNA puro e concentrado. Usando as folhas na fase de crescimento mesmo também é vital para a confiabilidade do ensai...

a cell-to-cell macromolecular transport assay in planta utilizing biolistic bombardment

Aqui, apresentamos um protocolo simples e rápida para detectar e avaliar a extensão da célula-célula de transporte macromolecular na planta. Neste protocolo, uma proteína fluorescente etiquetado de interesse é transitoriamente expressa no tecido vegetal após a entrega biobalística de seu DNA de codificação de construir. A distribuição intra-e intercelular da proteína com a tag é então analisada por microscopia confocal. Descrevemos esta tecnologia em detalhes, proporcionando passo-a-passo protocolos para análise e avaliar a extensão do transporte de proteínas simplástico em três espécies de plantas, Arabidopsis thaliana, Nicotiana benthamiana e N. tabacum (tabaco).
