“…At the same time, the transcripts for selected known low Fe markers BHLH38, BHLH100, and PYE were up. FIT and PYE are major regulators of root Fe uptake (for review, see Brumbarova et al, 2015). PYE associates with similar BHLH transcription factors (Selote et al, 2015).…”

“…Research on Fe homeostasis in plants has mainly focused on Fe uptake mechanisms in the roots and Fe distribution within the plants, resulting in the identification of several molecular factors involved in wholeplant Fe homeostasis (for recent reviews, see Kobayashi and Nishizawa, 2012;Brumbarova et al, 2015, Krohling et al, 2016. In addition to Fe uptake and redistribution, plants can also acclimate their metabolism when Fe supply cannot meet all needs (López-Millán et al, 2013).…”

“…Cross talk between plant hormones and NO is also considered critical for Fe-deiciency signaling [81]. Evidence obtained in Arabidopsis suggests interplay between ET and NO for upregulation of genes (AtFIT, AtbHLH39, AtFRO2, AtNAS1, AtNAS2, AtFRD3, AtMYB72) related to Fe-deiciency [82].…”

Phytohormones - Signaling Mechanisms and Crosstalk in Plant Development and Stress Responses

Plants, being sessile, are concurrently exposed to various biotic and abiotic stresses. The perception of stress signals in plants involves a wide spectrum of signal transduction pathways that interact to induce tolerance against adverse environmental conditions. This functional overlapping among various stress signaling cascades also leads to the expression of genes that regulate biosynthesis or action of other hormones. Phytohormonal signals, activated by both developmental and environmental responses, play a crucial role to develop stress tolerance in plants. Nitric oxide (NO) is one of the major players in plant signaling networks. Emerging evidence supports that NO interplays with signaling pathways of auxins, gibberellins, abscisic acid, ethylene, jasmonic acid, brassinosteroids, and other plant hormones to control metabolism, growth, and development in plants. This chapter focuses on the current state of knowledge of cross talk between signaling pathways of NO and phytohormones in plants exposed to various abiotic stresses.

“…The mechanisms for the regulation of Fe mobilization in the soil, for entry, and for distribution of Fe in the plant are promising targets for the breeding of Fe-biofortified crops, which is a strategy of high potential for counteracting Fe deficiency in humans. Arabidopsis (Arabidopsis thaliana) serves as a model plant to dissect Fe signaling at the molecular level, and transcription factors have become known as important checkpoints of the regulatory mechanisms controlling Fe homeostasis (Brumbarova et al, 2015).…”
