Natural Variation in Physiological Responses of Tunisian Hedysarum carnosum Under Iron Deficiency

Natural allelic variation of FRO2 modulates Arabidopsis root growth under iron deficiency

Low availability of Fe significantly limits crop yields in many parts of the world. However, it is largely unknown which genes and alleles adjust plant growth in Fe limited environments. Using natural variation of a geographically restricted panel of Arabidopsis thaliana accessions, we identify allelic variation at the FRO2 locus associated with root length under iron deficiency. We show that n...

Improving soybean leaf physiological responses under drought stress by increasing seed zinc and iron concentration

To study the effects of both drought stress and seed zinc and iron concentrations on the photosynthesis, chlorophyll fluorescence, and proline and carbohydrate accumulations in soybean (Glycine max (L.) Merr. cv. M9) leaf, a split plot experiment was carried out in 2012 based on a randomized complete block design with three replications in greenhouse conditions at Yasouj University. Drought str...

Pumping iron: conserved iron deficiency responses in the plant lineage.

Elevated carbon dioxide improves plant iron nutrition through enhancing the iron-deficiency-induced responses under iron-limited conditions in tomato.

The increases in atmospheric carbon dioxide (CO(2)) concentrations can enhance plant growth and change their nutrient demands. We report that when tomato (Lycopersicon esculentum 'Zheza 809') plants were grown in iron (Fe)-limited medium (with hydrous ferric iron oxide) and elevated CO(2) (800 microL L(-1)), their biomass and root-to-shoot ratio were greater than plants grown in ambient CO(2) (...

Physiological basis of drought tolerance in potato grown under long-term water deficiency

Coping with water shortages without compromising tuber yield is a majorchallenge for potato (Solanum tuberosum L.) production in northern China. In thisstudy, we used three potato cultivars with different sensitivities to drought toevaluate the effect of long-term drought stress on morphological and physiologicalcharacteristics under field conditions during three growing seasons (2009-2011).Our...
