Jasmonate signaling in plant interactions with resistance-inducing beneficial microbes.

abstract：:The objective of proteomics is to get an overview of the proteins expressed at a given point in time in a given tissue and to identify the connection to the biochemical status of that tissue. Therefore sample throughput and analysis time are important issues in proteomics. The concept of proteomics is to encircle the ...
