(Submitter supplied) Phosphorus (P) and iron (Fe) deficiency are major limiting factors for plant productivity worldwide. White lupin (Lupinus albus L.) has become a model plant for understanding plant adaptations to P and Fe deficiency, because of its ability to form cluster roots, bottle-brush-like root structures that play an important role in the uptake of P and Fe from soil. However, little is known about the signaling pathways involved in sensing and responding to P and Fe deficiency. more...

(Submitter supplied) Iron (Fe) and phosphorus (P) are essential nutrients for plants growth. Despite their abundance in soils, they are barely available for plants. In order to overcome these nutritional stresses, plants have evolved strategies including physiological, biochemical and morphological adaptations. Biosynthesis and release of low molecular weight compounds from the roots play a crucial role in P and Fe mobilization. more...

(Submitter supplied) Phosphorus, in its orthophosphate form (P(i)), is one of the most limiting macronutrients in soils for plant growth and development. However, the whole-genome molecular mechanisms contributing to plant acclimation to P(i) deficiency remain largely unknown. White lupin (Lupinus albus) has evolved unique adaptations for growth in P(i)-deficient soils, including the development of cluster roots to increase root surface area. more...

(Submitter supplied) Iron (Fe) deficiency is a yield-limiting factor for a variety of field crops across the world and generally results from the interaction of limited soil Fe bioavailability and susceptible genotype cultivation. Tomato, a Strategy I, model plant for Fe deficiency, is an important economical crop. Tomato responses in order to improve Fe uptake are based on acidification of rhizosphere, reduction of Fe3+ to Fe2+ and transport of Fe2+ into the cells.

(Submitter supplied) Soybean (Glycine max) is an important agricultural crop, but nutrient deficiencies frequently limit soybean production. While research has advanced our understanding of plant responses to long-term nutrient deficiencies, less is known about the signaling pathways and immediate responses to certain nutrient deficiencies, such as Pi and Fe deficiencies. Recent studies have shown that sucrose acts as a long-distance signal that is sent in increased concentrations from the shoot to the root in response to various nutrient deficiencies. more...

(Submitter supplied) Fe deficiency stimulates a coordinated response involving reduction, transport and redistribution of Fe in the roots. The expression of genes regulated by Fe deficiency in the two contrasting Arabidopsis thaliana ecotypes, Tsu-1 and Kas-1, shows that different ecotypes can respond in diverse ways, with different Fe regulated overrepresented categories. We use microarrays to analyze the Fe deficiency responses of contrasting Arabidopsis thaliana ecotypes (Tsu-1 and Kas-1).

(Submitter supplied) In the early stages (30 days) of phosphorus deficiency stress, Epimedium pubescens leaves cope with short-term phosphorus deficiency by increasing the expression of related genes such as carbon metabolism, flavonoid synthesis and hormone signal transduction pathways, producing sufficient energy, scavenging ROS, and adjusting plant morphology. However, with the extension of stress duration to 90 days, the expression of genes related to phosphorus cycling and phosphorus recovery (PHT1-4, PHO1 homolog3, PAP) was upregulated, and transcriptional changes and post-transcriptional regulation (miRNA regulation and protein modification) were enhanced to resist long-term phosphorus deficiency stress. more...

(Submitter supplied) The antagonistic interaction between iron (Fe) and phosphorus (P) has been noted in the area of plant nutrition. To understand the physiology and molecular mechanisms of this interaction, we studied the growth performance, nutrient concentration, and gene expression profiles of root and shoot segments derived from 10-d-old rice (Oryza sativa) seedlings under four different nutrient conditions: (1) full strength of Fe and P (+Fe+P); (2) full strength of P and no Fe (-Fe+P); (3) full strength of Fe and no P (+Fe-P); and (4) without both Fe and P (-Fe-P). more...
