Objective: To study the mechanism of plant growing promoted by Mycorrhizal fungus through the difference of proteomes.
Method: The differential proteomes between uninoculated and inoculated endophytic fungi, Epulorhiza sp. on Anoectochilus roxburghii were analyzed by two-dimensional gel electrophoresis and MALDI-TOF/TOF mass spectrum.
Result And Conclusion: Twenty-seven protein spots were analyzed by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Twenty-two candidate proteins were identified by database comparisons. The function of these proteins mostly involved in signal transduction, metabolic regulation, as well as photosynthesis and substance metabolism. The results indicate that the regulator control system of plant is influenced by fungi action, and the positive regulation improves substance metabolism and photosynthesis, which results in strong plant and higher resistance. It is also deduced that silent genes may exist in endosymbiosis plants.

Article Synopsis
- The homedomain-leucinezippper gene family influences plant growth and drought response, with ArHDZ19 being a key transcription factor from Anoectochilus roxburghii whose role was studied.
- ArHDZ19 is localized in the nucleus and its expression increases significantly under drought stress; overexpressing this gene in Arabidopsis thaliana led to taller plants, longer reproductive structures, and earlier flowering.
- Additionally, while ArHDZ19 enhances plant survival in drought conditions, it appears to modulate the expression of certain stress-responsive genes, suggesting it aids drought resistance through promoting earlier flowering as a potential avoidance strategy.
