Foraging for nitrogen
As sessile organisms, plants rely on their ability to adapt the development and growth of their roots in response to changing nutrient conditions. One such response, known to be displayed by plants grown in low nitrogen conditions, is the elongation of primary and lateral roots to explore the surrounding soil. (2019-06-07)

Researchers generate plants with enhanced drought resistance without penalizing growth
Extreme drought is one of the effects of climate change that is already being perceived. A team led by the researcher at the Centre for Research in Agricultural Genomics (CRAG) Ana CaƱo-Delgado has obtained plants with increased drought resistance by modifying the signaling of the plant steroid hormones, known as brassinosteroids. The study, published in Nature Communications, is the first to find a strategy to increase plant hydric stress resistance without affecting overall plant growth. (2018-11-08)

Plant growth requires teamwork between 2 hormones
Two growth-promoting groups of substances, or phytohormones, the gibberellins and the brassinosteroids, are used independently of each other for the breeding and production of crop plants. A team of scientists at Technical University of Munich has now discovered that the two act in concert -- without brassinosteroids, a plant is unable to produce gibberellins. (2015-08-17)

Hormones that guide root growth rates revealed
A plant's roots grow and spread into the soil, taking up necessary water and minerals. The tip of a plant's root is a place of active cell division followed by cell elongation, with different zones all working together to expand into new depths of the soil. Achieving an optimal root growth rate is critical for plant survival under drought conditions. New work reports the mechanisms that together determine the rate of root growth. (2015-04-09)

Revealing the workings of a master switch for plant growth
In a discovery that could pave the way to higher crop and biomass productivity, scientists from RIKEN in Japan, along with colleagues from the University of Tokyo, have shed new light on the complex interplay that allows a master switch to control the growth of plants. In the research, published in The Plant Cell, the group discovered a new cell mechanism, centered around a protein called BSS1/BZR1, that allows for precise control of plant height by regulating plant brassinosteroid signaling. (2015-02-06)

How steroid hormones enable plants to grow
Plants can adapt extremely quickly to changes in their environment. Hormones, chemical messengers that are activated in direct response to light and temperature stimuli help them achieve this. Plant steroid hormones similar to human sex hormones play a key role here. In the current edition of Nature Communications, scientists describe a new signaling mode for the brassinosteroid class of hormones. (2014-08-19)

The study has been published in the prestigious science journal Nature Cell Biology. (2012-04-03)

Steroids control gas exchange in plants
Plants leaves are sealed with a gas-tight wax layer to prevent water loss. Plants breathe through microscopic pores called stomata on the surfaces of leaves. As the key conduits for CO2 uptake and water evaporation, stomata are critical for both our climate and plant productivity. Thus, not surprisingly, the total number and distribution of stomata are strictly regulated by plants to optimize photosynthesis while minimizing water loss. But the mechanisms for such regulation have remained elusive until now. (2012-02-05)

Lift weights, eat mustard, build muscles?
If you want to lean out, add muscle and get ripped, new research in the FASEB Journal suggests to look to your garden for help. Scientists have found that when a specific plant steroid was ingested by rats, it triggered a response similar to anabolic steroids with minimal side effects. The stimulatory effect of homobrassinolide on protein synthesis in muscle cells led to increases in lean body mass, muscle mass, and physical performance. (2011-09-29)

New component of a plant steroid-activated pathway discovered
Plant biologists have been working for years to nail down the series of chemical signals that one class of plant hormones, brassinosteroids, send from a protein on the surface of a cell to the nucleus.

(2011-01-23)

Unlocking the secrets of a plant's light sensitivity
Plants are very sensitive to light conditions, in part due to a signal that activates special photoreceptors that regulate growth, metabolism, and physiological development. Scientists believe that these light signals control plant growth and development by activating or inhibiting plant hormones. New research from Carnegie plant biologists has altered the prevailing theory on how light signals and hormones interact. Their findings could have implications for food crop production. (2010-12-13)

Mastermind steroid found in plants
Scientists have known how important plant steroids called brassinosteroids are for regulating plant growth and development. But until now, they did not know how extensive their reach is. Now Carnegie researchers have identified about a thousand brassinosteroid target genes showing links between the steroid and numerous cellular functions and other hormonal chain reactions. The study is the first comprehensive action map for a plant hormone and will help accelerate basic plant science and crop research. (2010-11-15)

Antagonistic genes control rice growth
Scientists at the Carnegie Institution, with colleagues, have found that a plant steroid prompts two genes to battle each other -- one suppresses the other to ensure that leaves grow normally in rice and the experimental plant Arabidopsis thaliana, a relative of mustard.
