This study characterized the changes in proteinase activities in maize inbred line H60 and soybean cultivar Keller roots in response to anoxia. After 24 h of anoxia, crude protein extracts from both maize and soybean root tips (10 cm) were assayed for proteinase activities at pHs ranging from 4.5 to

Illumination of maize roots initiates changes in mRNA levels and in the activities of proteins within the root cap. Using Northern analysis we showed a 5-6 fold increase in the levels of three specific mRNAs and a 14-fold increase in plastid mRNA. This increase is rapid, occurring within 30 minutes
Synthesis of indole-3-acetic acid (IAA), using stable-isotope incorporation, was investigated in Zea mays L. Incorporation of 2H from ZH20 into IAA molecules was shown to occur in intact plantlets and excised primary roots cultured in vitro. This demonstrates the de-novo formation of IAA, a process
Oxygen is essential for aerobic life, although reactive oxygen intermediates can be highly toxic to cells. Superoxide radicals and hydrogen peroxide become particularly harmful __in vivo__ due to their reactivity with transition metals like iron, producing hydroxyl radicals, which are involved in DN
