Annotation and molecular characterisation of the TaIRO3 and TaHRZ iron homeostasis genes in bread wheat (Triticum aestivum L.) por Carey-Fung, Oscar, Beasley, Jesse T., Johnson, Alexander A. T.

“…The iron-related transcription factor 3 (IRO3), as well as haemerythrin motif-containing really interesting new gene (RING) protein and zinc finger protein (HRZ), are major regulators of Fe homeostasis in diploid species like Arabidopsis (Arabidopsis thaliana) and rice (Oryza sativa L.), but remain uncharacterised in hexaploid bread wheat (Triticum aestivum L.). …”

A model to incorporate the bHLH transcription factor OsIRO3 within the rice iron homeostasis regulatory network por Carey-Fung, Oscar, O'Brien, Martin, Beasley, Jesse T., Johnson, Alexander A. T.

“…The Fe homeostasis network is well characterized in Arabidopsis thaliana and remains poorly understood in monocotyledon species such as rice (Oryza sativa L.). Recent investigation of the rice Fe homeostasis network revealed OsIRO3, a basic Helix–Loop–Helix (bHLH) TF as a putative negative regulator of genes involved in Fe uptake, transport, and storage. …”

Role of phosphoenolpyruvate carboxylase in the adaptation of a tropical forage grass to low-phosphorus acid soils por Begum, Hasna Hena, Osaki, Mitsuru, Nanamori, Masahito, Watanabe, Toshihiro, Shinano, Takuro, Rao, Idupulapati M.

“…‘Mulato’ has adapted to acid soils with extremely low phosphorus (P) contents, its low-P-tolerance mechanisms were investigated and compared with those of wheat (Triticum aestivum L.) and rice (Oryza sativa L. cv. ‘Kitaake’). Among the three plant species, the highest P-use efficiency (PUE) in low-P soil was recorded in the Brachiaria hybrid, which increased remarkably under P-deficiency and soil acidity, while P-deficiency had less effect on the PUE of wheat and rice. …”
