Bacterial volatiles promote growth in Arabidopsis
Several chemical changes in soil are associated with plant growth-promoting rhizobacteria (PGPR). Some bacterial strains directly regulate plant physiology by mimicking synthesis of plant hormones,Expand
Root-Secreted Malic Acid Recruits Beneficial Soil Bacteria1[C][W][OA]
Beneficial soil bacteria confer immunity against a wide range of foliar diseases by activating plant defenses, thereby reducing a plant's susceptibility to pathogen attack. Although bacterial signalsExpand
Herbivore-infested plants selectively attract parasitoids
In response to insect herbivory, plants synthesize and emit blends of volatile compounds from their damaged and undamaged tissues, which act as important host-location cues for parasitic insects.Expand
Rhizobacterial volatile emissions regulate auxin homeostasis and cell expansion in Arabidopsis
Certain plant growth-promoting rhizobacteria (PGPR), in the absence of physical contact with a plant stimulate growth via volatile organic compound (VOC) emissions, through largely unknownExpand
An herbivore elicitor activates the gene for indole emission in maize.
Maize and a variety of other plant species release volatile compounds in response to herbivore attack that serve as chemical cues to signal natural enemies of the feeding herbivore.Expand
Soil bacteria confer plant salt tolerance by tissue-specific regulation of the sodium transporter HKT1.
Elevated sodium (Na(+)) decreases plant growth and, thereby, agricultural productivity. The ion transporter high-affinity K(+) transporter (HKT)1 controls Na(+) import in roots, yet dysfunction orExpand
De Novo Biosynthesis of Volatiles Induced by Insect Herbivory in Cotton Plants
In response to insect feeding on the leaves, cotton (Gossypium hirsutum L.) plants release elevated levels of volatiles, which can serve as a chemical signal that attracts natural enemies of theExpand
Soil bacteria augment Arabidopsis photosynthesis by decreasing glucose sensing and abscisic acid levels in planta.
Photosynthesis is regulated by environmental factors as well as endogenous sugar signals. Whereas light-driven sugar biosynthesis is essential for terrestrial organisms, as well as belowgroundExpand
Jasmonate‐deficient plants have reduced direct and indirect defences against herbivores
Plants employ a variety of defence mechanisms, some of which act directly by having a negative effect on herbivores and others that act indirectly by attracting natural enemies of herbivores. In thisExpand
A soil bacterium regulates plant acquisition of iron via deficiency-inducible mechanisms.
Despite the abundance of iron in nature, it is the third most limiting nutrient for plants due to its minimal solubility in most soils. While certain soil microbes produce chelating agents thatExpand
