Aluminum Alleviation of Iron Deficiency Chlorosis Is Conserved in Wild Rice Relative <i>Oryza rufipogon</i> and in Maize.

ABSTRACT: Aluminum (Al), an element that has no biological function described in plants, is commonly found in acidic soils, reducing plant growth, despite some beneficial effects reported in the literature. Iron (Fe) is an essential nutrient for plants, and Fe deficiency causes leaf interveinal chlorosis. Remarkably, rice (Oryza sativa), a C₃ crop considered tolerant to Al, shows alleviation of Fe deficiency chlorosis when exposed to Al, suggesting that Al can positively impact Fe homeostasis. However, whether this effect is observed only in rice or is common to other plant species is unknown. The rice wild progenitor Oryza rufipogon is closely related to the domesticated species, sharing several traits such as a semi-aquatic habit and use of the combined strategy for Fe upt
