The two major model plant species, rice and Arabidopsis, have the greatest number of entries and most detailed curation.
A considerable quantity of transcriptional data is currently available for major model plant species and in silico analyses can therefore be used to identify suitable HKGs for gene expression normalization in these species.
As for many other major model plant species, the release of the grapevine genome in 2007 [ 1] led to a rapid accumulation of "Omics -scale data and a burst Omics -scaleughput studata.
A major model plant, Arabidopsis has nectary tissues producing nectar and valuable tools to dissect the molecular mechanisms in nectary development [ 29], but the nectaries are miniscule and only secret nectar in trace amounts, which makes nectar collection and analysis a challenge [ 24].
Thus, systematic analysis of this family in rice (Oryza sativa), a major model crop plant, will be helpful in the design of effective strategies for functional analysis.
Presently, most of our knowledge of plant MYB genes was obtained from studies of the major genetic model plant, Arabidopsis, based on its well-annotated genome sequence.
Arabidopsis thaliana and rice (Oryza sativa L). are two major model species for plants with apparent differences in overall physiology, adaptation to temperature variation and cold tolerance.
Magnaporthe oryzae has emerged as a major model organism for plant microbe interactions.
Rice is one of the most important food crops in the world and it has been used as a major model species in plant (especially monocot) functional genomics research because of its relatively small genome size and extensively sequenced genome [ 32].
The early insights into transcriptome responses were primarily obtained from the glycophytic model plants and major crops such as Arabidopsis, rice, and maize, in which hundreds of potential salt-responsive genes were identified and analysed to determine their expression patterns under salt treatments.
