Understanding the dynamics of the transcriptome, proteome and metabolome in response to genetic, physiological, developmental and environmental factors at the level of a single cell still poses a major challenge to plant biologists. The single-celled seed trichomes of cotton are economically important fibers that possess many unique attributes of an excellent biological model highly amenable for addressing fundamental questions in plant growth and development. Not only are cotton fibers among the longest and fastest growing single cells in the plant kingdom, mature fibers are ~95% cellulose and much of our current understanding of cellulose biosynthesis was derived from the cotton model. The cotton fiber transcriptome is highly complex and remains one of the most well characterized of the single-celled transcriptomes studied to date. Master switches control stage-specific re-modeling of the cotton fiber transcriptome in response to developmental signals that control fiber morphogenesis, and in turn, dictate the fiber phenotype and important agronomic traits. Expression profiling experiments, coupled with genetic, structural, molecular and biochemical data have unveiled a number of novel processes crucial to cell morphogenesis and cell wall biogenesis that offers an unprecedented view of the regulation of developmental processes that links the genotype and phenotype, and paves the way for predictive modeling of the fiber transcriptome for the genetic enhancement of economically important agronomic traits.
