Phenylglycine is the organic compound with the formula C 6 H 5 CH(NH 2)CO 2 H. It is a non-proteinogenic alpha amino acid related to alanine, but with a phenyl group in place of the methyl group. It is a white solid. The compound exhibits some biological activity. [1]
Given the lack of knowledge of human infectious diseases at this time (and well into the 19th century) this was not an unusual conclusion, [15] but what is surprising is that while tulip mosaic disease has a far more impressive and documented history than any other plant virus, the realization that it was a communicable plant disease, let alone ...
N-Phenylglycine is an organic compound with the formula C 6 H 5 NHCH 2 CO 2 H. This white solid achieved fame as the industrial precursor to indigo dye . [ 1 ] It is a non-proteinogenic alpha amino acid related to sarcosine , but with an N - phenyl group in place of N - methyl .
It is analogous to the innate immune system found in animals, and commonly precedes a slower systemic (whole plant) response, which ultimately leads to systemic acquired resistance (SAR). [1] HR can be observed in the vast majority of plant species and is induced by a wide range of plant pathogens such as oomycetes, viruses, fungi and even ...
Injury in plants is damage caused by other organisms or by the non-living (abiotic) environment to plants. Animals that commonly cause injury to plants include insects, mites, nematodes, and herbivorous mammals; damage may also be caused by plant pathogens including fungi, bacteria, and viruses. Abiotic factors that can damage plants include ...
Over the millennia, pandemics that have killed millions of people have been caused by pathogens such as viruses, bacteria and fungi that crossed over to people from animals.
Plant viruses are generally transmitted by a vector, but mechanical and seed transmission also occur. Vectors are often insects such as aphids ; others are fungi , nematodes , and protozoa . In many cases, the insect and virus are specific for virus transmission such as the beet leafhopper that transmits the curly top virus causing disease in ...
References to diseases now known to be caused by phytoplasmas can be found as far back as 1603 (mulberry dwarf disease in Japan). [4]Such diseases were originally thought to be caused by viruses, which, like phytoplasmas, require insect vectors and cannot be cultured.
