Project description:As a response to insect attack, maize (Zea mays) has inducible defenses that involve large changes in gene expression and metabolism. Piercing/sucking insects such as corn leaf aphids (Rhopalosiphum maidis) cause direct damage by acquiring phloem nutrients as well as indirect damage through the transmission of plant viruses. To elucidate the metabolic processes and gene expression changes involved in maize responses to aphid attack, leaves of inbred line B73 were infested with R. maidis for two to 96 hours.
Project description:These maize (Zea mays L.) B73 cellular RNA samples were prepared from seedlings treated in 2 h water and extracted cellular RNA directly from frozen 1-mm root tips. They are parallel experiment to compare to two other types of RNA extracted from isolated nuclei.
