Root responses of contrasting rice genotypes to low temperature stress.

Rice (Oryza sativa L.) ssp. indica is the most cultivated species in the South of Brazil.

Unraveling Rice Tolerance Mechanisms Against Mite Infestation.

Rice is the staple food for over half of the world's population. Infestation of (Acari: Tetranychidae) causes great losses in rice productivity. To search for rice genotypes that could better tolerate infestation, we evaluated morphological and production parameters in Brazilian cultivars, and identified two cultivars with contrasting responses.

High infestation levels of Schizotetranychus oryzae severely affects rice metabolism.

High levels of Schizotetranychus oryzae phytophagous mite infestation on rice leaves can severely affect productivity. Physiological characterization showed that S. oryzae promotes a decrease in chlorophyll concentration and the establishment of a senescence process in rice leaves.
