HIGHLIGHTS
Sakthivel Kailasam, Ying Wang, Jing-Chi Lo, Hsin-Fang Chang and Kuo-Chen Yeh* (2018) S-nitrosoglutathione works downstream of nitric oxide to mediate iron deficiency signaling in Arabidopsis The Plant Journal, DOI: 10.1111/tpj.13850
Several studies elucidated the transcriptional responses to iron (Fe) starvation, however, the Fe sensing and signal transduction machineries are poorly resolved thus far in plants. With this focus, by using chemical biology approach, we identified a small molecule R7, whose use inhibited the physiological and molecular responses of Fe starvation in Arabidopsis. R7 blocked the Fe starvation signaling from nitric oxide (NO) to the central transcription factor, FER-LIKE IRON-DEFICIENCY-INDUCED TRANSCRIPTION FACTOR (FIT). Exogenous applications of NO abduct, S-nitrosoglutathione (GSNO) were able to attenuate the R7 effect. R7 directly or indirectly decreased the endogenous GSNO levels in roots but not the NO levels. Our finding reveals that, under Fe limited situation the starvation signal from NO is passed to FIT through GSNO. link

Background: Two related species accumulate differences between each other over time. If one of the species is domesticated due to human selection of desirable traits, the domesticated species experiences a 'bottleneck' where many traits present in the related wild species are lost because only a few individuals are targeted for selection. ...more
