Examples
“When a terminal bud or growing tip is removed from the parent plant, a growth-suppression hormone called auxin is removed as well.”
ScrippsNews - current events, culture, commentary, community
“Arabidopsis thaliana that are defective in the formation of continuous vascular network: calling the auxin signal flow canalization hypothesis into question.”
“Building on previous observations, a group of scientists in the Department of Gerd Jürgens at the Max Planck Institute for Developmental Biology, together with scientists in Belgium, described the necessity of combining increased cell cycle activity and auxin, which is one of the major plant hormones, to give rise to an increase in root branching.”
“The plant hormone auxin, which is important for nearly every one of the plant's developmental processes, accumulates at the site of infection.”
“Leyser and her lab study the role of plant hormones, such as auxin, in plant growth.”
“The researchers found that GAs interact with other plant hormones such as auxin to tell the plant whether to concentrate on reaching for the sky or on building a bigger, better network of roots under ground.”
“These facts made me think that there must be a plant hormone, other than auxin, that is capable of inhibiting shoot branching-a branching-inhibiting hormone that this did not function in the mutant, resulting in excess shoot branching. ”
“Mist spray, constant heat of 28C, and auxin mixtures of IBA and NAA appear essential to good rooting (Zeijlemaker, 1976).”
“The mechanism where this is accomplished is differential growth, which is in turn (see p. 90) sparked by the greater activity of auxin on the shaded side of the growing tip of the stem.”
“The auxin solution is prepared as recommended by G.H. Poesch in the”
