Mimosa pudica was one of the four species that significantly extracted and bioaccumulated the pollutant into its leaves. [25] Other studies have found that Mimosa pudica extracts heavy metals such as copper, lead, tin, and zinc from polluted soils. This allows for the soil to gradually return to less toxic compositions.
Mimosa pudica also show thermotropism by the collapsing of leaf petioles leading to the folding of leaflets, when temperature drops. [1] The term "thermotropism" was originated by French botanist Philippe Van Tieghem in his 1884 textbook Traité de botanique. Van Tieghem stated that a plant irradiated with an optimum growth temperature on one ...
Collagen is a complex hierarchical material with mechanical properties that vary significantly across different scales. On the molecular scale, atomistic and course-grained modeling simulations, as well as numerous experimental methods, have led to several estimates of the Young's modulus of collagen at the molecular
Mimosa pigra was described as having an erect prickle between the pinnae and Mimosa asperata as having prickles in opposite pairs between the pinnae. [3] Further research showed that both leaf forms can occur on the same plant, and consequently both species were united under the name Mimosa asperata asperata, and later on, renamed Mimosa pigra.
Collagen IV has been the focus of extensive research ranging from biochemistry perspectives, to pathology, and genetic disorders. This is the only collagen type that is encoded by six different genes. The six α-chains of collagen IV can recognize each other with incredible specificity and will assemble into unique heterotrimers. After ...
Even though nitrogen is a necessary element for life, too much of it in water can have negative effects on aquatic ecosystems and endanger human health. Agricultural runoff, where fertilizers containing nitrogen compounds can seep into rivers, lakes, and groundwater, is one of the main sources of nitrogen in water.
The following species in the flowering plant genus Mimosa are accepted by Plants of the World Online. [1] About 90% of its hundreds of species are found in the Neotropics . [ 2 ]
Viburnum lesquereuxii leaf with insect damage; Dakota Sandstone (Cretaceous) of Ellsworth County, Kansas. Scale bar is 10 mm. Knowledge of herbivory in geological time comes from three sources: fossilized plants, which may preserve evidence of defense (such as spines) or herbivory-related damage; the observation of plant debris in fossilised animal feces; and the structure of herbivore mouthparts.
