Other auxin-like compounds are used as selective weed killers (e.g., to disturb the leaf growth of dicotyledonous plants either in fields containing monocotyledonous cereal crops or on lawns) and as agents that remove leaves from dicotyledonous plants (defoliating agents). (britannica.com)
The downward growth of roots is also associated with a greater quantity of auxin in their lower halves. (britannica.com)
This effect, which is the opposite to that found in coleoptiles, is attributed to an inhibitory action of auxins on root growth, but this aspect of auxin action is not yet fully understood. (britannica.com)
In plants, auxin is made from tryptophan and related to serotonin. (smallfarmcanada.ca)
Quantitative real-time PCR was used to test the expression of ZmCAMTA genes under several abiotic stresses (drought, salt, and cold), various stress-related hormones [abscisic acid, auxin, salicylic acid (SA), and jasmonic acid] and biotic stress [rice black-streaked dwarf virus (RBSDV) infection].

Research conducted by three independent groups and reported in The Plant Cell shows that fundamental developmental processes controlled by the plant hormone auxin are regulated by microRNAs in the model plant Arabidopsis thaliana. (sciencedaily.com)
The plant hormone indole-3-acetic acid (IAA), commonly referred to as auxin, plays a major role in regulating plant growth and development. (sciencedaily.com)
Auxin influences development by affecting the expression of numerous genes that control the processes of cell division and cell expansion in specific plant tissues at specific stages during the plant life cycle - e.g. for leaves, roots, and floral organs to develop in the correct patterns and correct time sequence. (sciencedaily.com)
Research reported in The Plant Cell shows that microRNAs control the accumulation of transcription factor proteins that regulate the expression of genes in the auxin response pathway. (sciencedaily.com)
Auxin is known to be a major regulator of adventitious root formation and normal Arabidopsis plants form multiple adventitious roots on the hypocotyl (stem just above the root) when treated with auxin but the ago1 mutants do not. (sciencedaily.com)
Although there is ample evidence that the inhibition of bud outgrowth by auxin from the shoot apex is linked to stem elongation and highly branched auxin biosynthesis or signaling mutants are dwarf, the third theory proposed in the 1930s, the indirect theory, that explains apical dominance as auxin-induced stem growth indirectly inhibits bud outgrowth has been overlooked. (frontiersin.org)
Since a growing stem is a strong sink for sugars, and sugar is indispensable for shoot branching, the indirect theory of apical dominance might now be explained as auxin-induced stem growth inhibits bud outgrowth by diverting sugars away from buds. (frontiersin.org)
Soon after the discovery that the apical signal that inhibits axillary bud outgrowth is the plant hormone auxin ( Thimann and Skoog, 1933 ), three theories - direct, diversion, and indirect (Figure 1 ) - were proposed to explain the phenomenon of apical dominance (reviewed in Snow, 1937 ). (frontiersin.org)
The direct theory explains apical dominance as auxin synthesized in the shoot apex moves down the stem into buds and inhibits their growth. (frontiersin.org)
According to this theory, apically derived auxin inhibits buds from synthesizing their own auxin necessary for their growth. (frontiersin.org)
The second, diversion, theory of the 1930s explains the phenomenon of apical dominance as auxin from the shoot apex prevents growth promoting factors synthesized in roots and cotyledons from entering into buds and stimulate bud outgrowth. (frontiersin.org)

In fact, a greatly reduced supply of phosphorus is already sufficient to trigger the development into a carnivorous plant, according to the scientist. (sciencedaily.com)
This work provides an important contribution to our understanding of plant development. (sciencedaily.com)
Cell signaling in plant development usually involves a receptor (i.e. for a hormone or light molecule) and a signal transduction pathway, which concludes with a cellular response that is relevant to the plants development. (hightimes.com)
Background: Mining-related waste materials are characterized to determine if they are suitable for sustaining plant growth and development. (cdc.gov)
One thousand days refers to the period from pregnancy through a child's second birthday, when optimal nutrition is critical for brain development, healthy growth, and setting children on a trajectory for lifelong health. (cdc.gov)
Iodine is essential for the growth and development of children. (cdc.gov)

From the genomes we can also get molecular data to see how the plants evolve. (lu.se)

Amending large landscape beds with organic matter is always better than simply amending a planting hole. (clemson.edu)
For a landscape bed, evenly apply a 1 to 1½-inch deep layer of organic matter over the planting bed, and then thoroughly mix by tilling to 6 or 7 inches deep. (clemson.edu)

We describe some of the results that suggest an interaction at the transcriptional level between ethylene, other hormones, and stress signals. (nih.gov)
