Here, we describe two members of the Arabidopsis (Arabidopsis thaliana) Yellow Stripe-Like (YSL) family, AtYSL1 and AtYSL3. The YSL1 YSL3 proteins are oligopeptide transporter family predicted to be integral membrane proteins. similar maize (Zea mays) YS1 phytosiderophore (ZmYS1) AtYSL2 iron (Fe)-nicotianamine transporter, transport metal-nicotianamine complexes into cells. mRNAs expressed in both root shoot tissues, regulated response Fe status plant. Beta-glucuronidase reporter expression,...
Abstract Several members of the Yellow Stripe-Like (YSL) family proteins are transporters metals that bound to metal chelator nicotianamine or related set mugineic acid chelators known as phytosiderophores. Here, we examine physiological functions three closely Arabidopsis (Arabidopsis thaliana) YSL members, AtYSL1, AtYSL2, and AtYSL3, elucidate their role(s) in allocation into various organs Arabidopsis. We show AtYSL3 AtYSL1 localized plasma membrane function iron yeast functional...
The mechanisms of root iron uptake and the transcriptional networks that control root-level regulation have been well studied, but by which shoots signal status to roots remain opaque. Here, we characterize an Arabidopsis (Arabidopsis thaliana) double mutant, yellow stripe1-like stripe3-like (ysl1ysl3), has lost ability properly regulate deficiency-influenced gene expression in both shoots. In spite markedly low tissue levels iron, mutant does not up- down-regulate deficiency-induced...
Understanding how seeds obtain and store nutrients is key to developing crops with higher agronomic nutritional value. We have uncovered unique patterns of micronutrient localization in using synchrotron X-ray fluorescence (SXRF). Although all four members the Arabidopsis thaliana Mn-CDF family can transport Mn, here we show that only mtp8-2 has an altered Mn distribution pattern seeds. In mutant, no longer accumulates hypocotyl cortex cells sub-epidermal embryonic cotyledons, but rather Fe...
