Brachypodium distachyon as a new model system for understanding iron homeostasis in grasses: phylogenetic and expression analysis of Yellow Stripe-Like (YSL) transporters

Abstract: PS secretion by brachypodium parallels that of related crop species such as barley and wheat. A single grass species-specific YSL clade is present, and expression of the BdYSL members of this clade could not be detected in shoots or roots, suggesting grass-specific functions in reproductive tissues. Finally, the Fe-responsive expression profiles of several YSLs suggest roles in Fe homeostasis.

“…This has led to the development of new model systems, closer to species of economic relevance for humans. For temperate poaceous crops like wheat and barley, the small, fast growing grass Brachypodium distachyon has become a promising model organism (Mur et al, 2011; Brkljacic et al, 2011; Vogel and Hill, 2008; Huo et al, 2008; Yordem et al, 2011; Garvin, 2008; Draper et al, 2001). The intrinsic properties of B. distachyon , including self-fertility, its short life cycle, a small sequenced diploid genome, and its genetic accessibility, make it highly suitable as a laboratory model plant.…”

“…Now that several plant genomes have been sequenced, it is clear that higher plants possess four distinct, well-conserved groups of YSL proteins, and that one of these is unique to grass species (Curie et al, 2009; Yordem et al, 2011). Substantial progress has been made in understanding the roles of the YSLs that are most closely related to ZmYS1 [e.g., AtYSL1, AtYSL2 and AtYSL3 (DiDonato et al, 2004; Waters et al, 2006; Chu et al, 2010) and OsYSL2 (Koike et al, 2004; Inoue et al, 2006; Ishimaru et al, 2010)], but there is little information concerning members of the other two conserved YSL clades.…”

“…Supplemental light was supplied with high-pressure sodium lamps to give a 20 h light period each day. For quantitative polymerase-chain-reaction (PCR) analysis, plants were grown in a sand:Turface mix (9:1 v/v) irrigated with water until germination and then irrigated with modified Hoagland’s nutrient solutions, with 1 mM KH 2 PO 4 , 3.75 mM KOAc, 5 mM Ca(NO 3 ) 2 , 1.25 mM KNO 3 , 2 mM MgSO 4 , 3.75 mM NH 4 OAc, 46 uM H 3 BO 3 , 9.1 uM MnCl 2 , 0.77 uM ZnSO 4 , 0.32 uM CuSO 4 , and 0.83 uM H 2 MoO 4 (Yordem et al, 2011) containing 100 ÎŒM FeSO 4 -EDTA every 48 h. Plants were grown for 10 days after germination before the root tissue was collected.…”
