An unexpected outcome of atmospheric CO2 enrichment
Mycorrhizae help plants acquire soil nutrients but also drain substantial carbon from plants. Whether mycorrhizae help or hinder plant growth depends upon the balance between nutrient benefits and carbon costs. The forthcoming issue of Ecology Letters demonstrates that enrichment of atmospheric CO2 and soil N interacts with mycorrhizae to structure the species composition of experimental plant communities. This study emphasizes the need to consider mycorrhizal interactions when predicting plant community responses to global change factors. (2003-05-22)

Genetics may lie at the heart of crop yield limitation
You might think that plants grow according to how much nutrition, water and sunlight they are exposed to, but new research by Dr. Nick Pullen and a team from the John Innes Centre, UK shows that the plant's own genetics may be the real limiting factor. (2017-07-04)

'Thermometer' protein regulates blooming
As average temperatures rise every year, it is no longer rare to see plants flower as early as February. Behind this phenomenon is a complex of proteins whose activity is controlled by temperature changes, as has just been demonstrated by researchers. The Evening Complex regulates the expression of genes involved in plant growth and flowering, as a function of exterior temperatures, but the research team has shown that only one protein acts as a thermosensor. (2020-03-23)

New insights into radial expansion of plants can boost biomass production
Besides the obvious longitudinal growth, plants also enlarge in the radial sense. This thickening of plant stems and roots provides physical support to plants, provides us with wood and cork, and plays a major role in sequestering atmospheric carbon into plant biomass. The tissues responsible for this radial expansion are the vascular tissues which transport water and nutrients around plants and are visible as concentric circles in tree trunks known as annual growth rings. (2019-02-08)

A molecular break for root growth
The dynamic change in root growth of plants plays an important role in their adjustment to soil conditions. Depending on the location, nutrients or moisture can be found in higher or lower soil layers. This is why, depending on the situation, a short or a long root is advantageous. Caroline Gutjahr, Professor of Plant Genetics at the Technical University of Munich (TUM), and her team investigate how plant hormones influence the growth of roots. (2020-10-26)

Soy protein-based seed coating acts as biostimulant
Researchers developed a seed coating for broccoli seedlings using soy flour as a binder in a soy flour, cellulose, and diatomaceous earth coating formulation. Soy flour acted as a biostimulant to enhance plant growth and nitrogen uptake in the plants. Soy flour-coated seeds had greater seedling root and shoot growth, and when applied at 30 percent, 40 percent, and 50 percent, soy flour increased total nitrogen per plant compared with the noncoated control. (2016-11-14)

Not just another brick in the (plant cell) wall
In a new study revealing key steps for controlling plant growth, Australian researchers have shown how the assembly of components of the plant cell wall regulates growth of root hairs.

Research highlights the importance of 'self-DNA' for maintaining diversity among species
In natural plant communities, diversity is maintained by limits set on each plant by itself. This involves a detrimental effect of self-DNA -- DNA from the same species released during decomposition -- on the plant's and its offspring's growth. New research finds that this process not only regulates plant populations but may also be generalized to a range of additional organisms including algae, protozoa, fungi, and animals. (2015-04-20)

Salt-tolerant gene found in simple plant nothing to sneeze at
Whether a plant withers unproductively or thrives in salty conditions may now be better understood by biologists. The cellular mechanism that controls salt tolerance has been found in the arabidopsis plant by Texas AgriLife Research scientist Dr. Hisashi Koiwa, and an international team. Complex-N-glycan, a carbohydrate linked to a protein in plant cells, was previously thought to have no helpful function for plant growth and to cause certain allergies in humans, said Koiwa. (2008-04-07)

Research identifies possible on/off switch for plant growth
New research from UC Riverside identifies a protein that controls plant growth -- good news for an era in which crops can get crushed by climate change. When the protein, IRK, is present, the root perceives a signal telling cells not to divide. (2020-01-13)

Understanding plants' overactive immune system will help MU researchers build better crops
A plant's immune system protects the plant from harmful pathogens. If the system overreacts to pathogens, it can stunt plant growth and reduce seed production. Now, University of Missouri researchers have identified important suppressors that negatively regulate the responses of the immune system in the plant species Arabidopsis thaliana. Understanding the immune system of plants would allow breeders to create better yielding crop plants. (2009-05-27)

(2002-02-28)

The balancing act between plant growth and defense
Kumamoto University researchers have pinpointed the mechanism that regulates the balance between plant growth and defense. Excessive accumulation of hormones that protect against pathogen infection significantly hinders plant growth. Researchers found that the DEL1 gene plays a role in balancing growth and defense of plants infected with nematodes. This finding is expected to contribute to the improvement of agricultural crop varieties and the identification of infection mechanisms of various pathogens. (2020-06-16)

Researchers identify new target to boost plant resistance to insects and pathogens
Plants have evolved unique and sophisticated immune systems to defend themselves against insects and pathogens. Plant hormones called jasmonates play an important role in this defense, but jasmonates have been found to also be important for plant growth. Now, researchers have discovered a gene in the jasmonate pathway that controls plant defenses but does not play a detectable role in plant development. These findings could be applied to improve crop resistance in agriculture. (2013-05-23)
