Method to identify tissue specific genes in plant species?

Question

[kozhaki.seq]

I have microarray dataset consists of different tissue expression profiles from oryza sativa (rice). I was using clustering analysis (for ex, k-means clustering) to find tissue specific genes. Is there any better/alternative method or package available for finding tissue specific genes?

FYI: Similar question was asked previously and the comments indicate that TiGER is an example if the organism is human or other vertebrate.

Tissue specificity index (tau) is a very good measure and can be calculated readily from the microarray or NGS data. Other measures exist as well and are very nicely described here http://bib.oxfordjournals.org/content/early/2016/02/17/bib.bbw008.full

I never come across the article. Thanks @microguge
