Carrion flower Borneo and Sumatra. It can grow to be 3 feet across and weigh up to 15 pounds. "R. arnoldii" is a parasitic plant on "Tetrastigma" vine, which grows only in primary rainforests. It has no visible leaves, roots, or stem. It does not photosynthesize, but rather uses the host plant to obtain water and nutrients. Plants in the genus "Stapelia" are also called "carrion flowers". They are small, spineless, cactus-like succulent plants. Most species are native to South Africa, and are grown as potted plants elsewhere. The flowers of all species are hairy to varying degrees and generate the odor
Plant matrix metalloproteinase increase of transcript abundance with aging. In the leaves, the MMP gene was expressed in the phloem, developing xylem elements, neighboring mesophyll cell layers, and epidermal cells. The flowers were noted as having the gene in pistils, ovules, and receptacles. It was concluded that the At2-MMP has a physiological role in mature aging tissue and the possibility of being involved in plant senescence. The fungus Chondrostereum purpureum, the causal agent of silver leaf, was grown in liquid culture and agar, which caused it to secrete extracellular proteinases into the medium. The fluid dialysed by the activation of metal ions, which
