Iron is essential for most living organisms and is often the major limiting nutrient for normal growth. Plants induce iron utilization systems under conditions of low iron availability, but the molecular mechanisms of gene regulation under iron deficiency remain largely unknown. We identified the rice transcription factor IDEF1, which specifically binds the iron deficiency-responsive cis-acting...

OBJECTIVE In vitro production of a definitive endoderm (DE) is an important issue in stem cell-related differentiation studies and it can assist with the production of more efficient endoderm derivatives for therapeutic applications. Despite tremendous progress in DE differentiation of human embryonic stem cells (hESCs), researchers have yet to discover universal, efficient and cost-effective p...

Human-induced pluripotent stem cells (hiPSCs) are considered to be potentially able to differentiate into all human cell lineages and thus hold promise as an unlimited source for cell replacement therapies in clinical applications. Definitive endoderm (DE) formation is the first and crucial step in the development of visceral organs such as liver, lung, pancreas and so forth. Therefore, efficie...

Rice plants (Oryza sativa L.) utilize the iron chelators known as mugineic acid family phytosiderophores (MAs) to acquire iron from the rhizosphere. Synthesis of MAs and uptake of MA-chelated iron are strongly induced under conditions of iron deficiency. Microarray analysis was used to characterize the expression profile of rice in response to iron deficiency at the genomic level. mRNA extracte...
