title: Diploid and tetraploid tall wheatgrasses: valuable wild relatives of wheat at risk from taxonomic lumping, assumptions in gap analyses, and habitat loss
abstract: Abstract Wild genetic resources for tetraploid ( Triticum turgidum L.) and hexaploid ( T. aestivum L.) wheats include diploid and tetraploid taxa from the tall wheatgrass morphological complex, which, along with the wheats, are in the Triticeae grass tribe. These wild taxa are caespitose perennials with a littoral circum-Mediterranean distribution and they present several traits increasingly useful for wheat improvement in response to challenges precipitated by climate change. The active taxonom
