Exempel på hur man kan använda AUXIN i en mening

• The apical bud produces a plant hormone, auxin (IAA), that inhibits growth of the lateral buds further down on the stem towards the axillary bud.

• Thimann – Founding Provost notable for his research in biology; in 1934, obtained and isolated pure auxin, an important plant-growth hormone and, with several coworkers, proved that auxin promotes cell elongation, formation of roots, and growth of buds, discoveries that led to the development of a widely used synthetic auxin, 2,4-D.
• Chemist and Actonian Prize winner, Louis Wain developed synthetic auxin selective herbicides 2,4-DB, MCPB and Bromoxynil at Wye in the 1950s alongside his other research into insecticides, plant growth regulators and fungicides.
• The culture medium is supplemented with plant growth regulators, such as auxin, cytokinin, and gibberellin, to initiate callus formation or somatic embryogenesis.
• By the end of 1941 it was clear to the Templeman group that MCPA was one of the most active compounds tested but other auxin herbicides including 2,4-D were also effective.
• After graduating from the University of Utrecht, The Netherlands in 1927 with a dissertation on the effects of the plant hormone auxin, Went then worked as a plant pathologist in the research labs of the Royal Botanical Garden in Buitenzorg, Dutch East Indies (now Bogor, Indonesia) from 1927 to 1933.
• Kinetin is often used in plant tissue culture to induce callus formation (in conjunction with auxin) and regenerate shoot tissues from callus (with lower auxin concentration).
• Studies using Brassica rapa indicate that the light quality and ratio available to seedlings is sensed in the cotyledons, which upregulates the production of auxin.
• Aux/IAA proteins bind to auxin response factor (ARF) proteins, forming a heterodimer, suppressing ARF activity.
• The effector interacts with host machinery to induce transcription for genes that regulate plant hormones such as gibberellin and auxin.
• His eldest son was the Dutch botanist Frits Warmolt Went, who in 1927 as a graduate student worked on plant hormones, specifically the role of auxin in phototropism.
• 2,4,5-Trichlorophenoxyacetic acid (also known as 2,4,5-T), a synthetic auxin, is a chlorophenoxy acetic acid herbicide used to defoliate broad-leafed plants.
• Cytokinin, another plant hormone, has also been seen to play a role in maintaining and developing the meristematic tissue of the root, and can often have an antagonistic relationship with auxin in root development.
• Currently, it is theorized the regulation of plant villins are caused by degradation via the binding protein auxin, which targets the headpiece domain (VHP).
• The export of auxins from cells is termed auxin efflux and the entry of auxin in to cells is called auxin influx.
• Dicamba is a synthetic auxin that functions by increasing plant growth rate, leading to senescence and cell death.
• Tryptophan is the precursor to 5-hydroxytryptophan and then serotonin, tryptamine, auxin, kynurenines, and melatonin.
• It is often used in combination with other chemically related herbicides such as 2,4-D, dicamba, and MCPA, which mimic the plant hormone IAA (auxin) and kill most broadleaf weeds by causing uncontrolled growth.
• He developed an auxin which is instrumental in preserving the style and stigma of the citron; these features figure prominently in determining the halachic status of individual citrons for use as etrogim.
