Abstract

In plants, ferritin proteins play an important role in iron (Fe) storage which contributes to plant growth and development. However, the biological functions of ferritins in fruit trees are essentially unknown. In this study, three Ferritin genes were isolated from 'Zhentong No. 3' peach, which were named PpFer1-PpFer3. The expression levels of these genes were different in distinct tissues/organs. Notably, PpFer1 was the most abundantly expressed Ferritin family gene in all tested tissues of 'Zhentong No. 3' peach; its expression levels were significantly enhanced throughout the entire peach seedling under Fe toxicity and H2O2 stress, particularly in the leaves. In addition, over-expression of PpFer1 was effective in rescuing the retarded growth of Arabidopsis fer1-2 knockout mutant, embodied in enhanced fresh weight, primary root length, lateral root numbers, total root length, total leaf chlorophyll, stomatal conductance (Gs), net photosynthetic rate (Pn), transpiration rate, and tissue Fe concentration. This study provides insights into understanding the molecular mechanisms of Fe storage and sequestration in perennial fruit trees. [ABSTRACT FROM AUTHOR]

11. The Milk of Birds

Author

Sylvia Whitman and Sylvia Whitman

Abstract

This timely, heartrending novel tells the moving story of a friendship between two girls: one an American teen, one a victim of the crisis in Darfur.Know that there are many words behind the few on this paper… Fifteen-year-old Nawra lives in Darfur, Sudan, in a camp for refugees displaced by the Janjaweed's trail of murder and destruction. Nawra cannot read or write, but when a nonprofit organization called Save the Girls pairs her with an American donor, Nawra dictates her thank-you letters. Putting her experiences into words begins to free her from her devastating past—and to brighten the path to her future. K.C. is an American teenager from Richmond, Virginia, who hates reading and writing—or anything that smacks of school. But as Nawra pours grief and joy into her letters, she inspires K.C. to see beyond her own struggles. And as K.C. opens her heart in her responses to Nawra, she becomes both a dedicated friend and a passionate activist for Darfur. In this poetic tale of unlikely sisterhood, debut author Sylvia Whitman captures the friendship between two girls who teach each other compassion and share a remarkable bond that bridges two continents.
