Organ accumulation and subcellular location of Cicer arietinum ST1 protein

The ST (ShooT Specific) proteins are a new family of proteins characterized by a signal peptide, tan-dem repeats of 25/26 amino acids, and a domain of unknown function (DUF2775), whose presenceis limited to a few families of dicotyledonous plants, mainly Fabaceae and Asteraceae. Their functionremain...
