Abstract

The roots of the "shy plant" Mimosa pudica L. emit a cocktail of small organic and inorganic sulfur compounds into the environment, including SO2, methylsulfinic acid, pyruvic acid, lactic acid, ethanesulfinic acid, propane sulfinic acid, 2-mercaptoaniline, S-propyl propane 1-thiosulfinate, and thioformaldehyde, an elusive and highly unstable compound never before reported to be emitted by a plant. When soil around the roots is dislodged or when seedling roots are touched, an odor is detected. The perceived odor corresponds to emission of higher amounts of propanesulfenic acid, 2-mercaptoaniline, S-propyl propane 1-thiosulfinate, and phenothiazine. The mechanosensitivity response is selective. Whereas touching the roots with soil or human skin resulted in odor detection, agitating the roots with other materials such as glass did not induce a similar response. Light and electron microscopy studies revealed the presence of microscopic sac-like root protuberances. Elemental analysis of these hairs by energy dispersive X-ray spectroscopy revealed them to contain higher levels of K+ and Cl- compared to the surrounding tissue. Exposing the hairs to stimuli that caused in odor emission resulted in a reduction in the levels of K+ and Cl- in the touched area. The mechanistic implications of the variety of sulfur compounds observed vis-à-vis the pathways for their formation are discussed.

Attention Score in Context

This research output has an Altmetric Attention Score of 209. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 July 2020.
All research outputs
#105,530
of 18,110,549 outputs
Outputs from Plant Physiology
#2
of 10,382 outputs
Outputs of similar age
#2,468
of 377,072 outputs
Outputs of similar age from Plant Physiology
#1
of 71 outputs
Altmetric has tracked 18,110,549 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 99th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 10,382 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.3. This one has done particularly well, scoring higher than 99% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 377,072 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 99% of its contemporaries.
We're also able to compare this research output to 71 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 99% of its contemporaries.
