A striking number of papers from numerous laboratories have been published on M. truncatula genomics. Topics range from whole genome transcript profiling to molecular mapping of traits. However, a detailed growth analysis has not been performed for this species. A detailed growth analysis must be performed under highly controlled conditions to identify stages of growth and development from which a uniform nomenclature can be devised. Here we report a detailed growth analysis of M. truncatula grown in growth chambers under tightly controlled conditions. Plants were grown either under nutrient sufficiency or under conditions of low phosphorus (P) or low nitrogen (N). Models having a well-defined nomenclature were developed. This research provides a platform for comparative growth studies of M. truncatula from any laboratory. Such a platform allows valid comparisons of M. truncatula across laboratories.
