Two Arabidopsis thaliana ABC transporter genes linked to auxin transport by various previous results were studied in a reverse-genetic fashion. Mutations in Multidrug Resistance-Like1 (MDR1) reduced ...

American Journal of Botany, Vol. 94, No. 11 (Nov., 2007), pp. 1745-1755 (11 pages) Axillary meristems play a fundamental role in inflorescence architecture. Maize (Zea mays) inflorescences are highly ...

What determines the pattern of root growth has until now been a mystery, but a new paper in PLoS Biology shows that the shape of the existing root can determine how further roots branch from it ...

Why are sunflowers always blooming with their “smile faces” to the Sun? This fascinating phenomenon is controlled by auxin existing in plants. Auxin, a plant hormone, is involved in regulating almost ...

Although the physiological function of most of these compounds has been studied for decades, the last 10 to 15 years have seen dramatic progress in our understanding of the molecular mechanisms of ...

Findings that two mutated genes alter plant growth and development could result in improved plants and enhanced cancer treatments, according to Purdue University researchers. WEST LAFAYETTE, Ind. - ...

A sophisticated mechanism that allows plant roots to quickly respond to changes in soil conditions has been identified by an international research team. Scientists from the John Innes Centre and ...

Auxin plays a central role in plant life. The hormone regulates various processes, from embryonic development to the formation of roots and the directional growth in response to light and gravity.

Leiden and Austrian researchers have succeeded in further uncovering how a plant cell passes on the growth hormone auxin in a directional manner to the next cell. Three proteins that cling together in ...

Astrounaut Ron Garan watering cucumber seeds in Japanese module of ISS. Scientists have untangled the competing influences of water and gravity on plant roots–by growing cucumbers during spaceflight.
