Anatomical Alterations in Plant Tissues Induced by Plant-Parasitic Nematodes
Plant-parasitic nematodes (PPNs) interact with plants in different ways, for example, through subtle feeding behavior, migrating destructively through infected tissues, or acting as virus-vectors for nepoviruses. They are all obligate biotrophic parasites as they derive their nutrients from living cells which they modify using pharyngeal gland secretions prior to food ingestion. Some of them ca...
متن کاملOxidation of paraffins by plant tissues.
Paraffins are fotund in almost every organism, plants (2), animals (13), and microorganismiis (14). The most common biological source of paraffins appears to be the surface lipids of plants (2), the chain length of the most abulndant paraffin being most often C., or C.:. These natural paraffins cant be readily catabolized by soil organisms (5) and to a limited extent bv an,inlals (6). The mecha...

as far as possible. The precautions described above have been found to be necessary in order to achieve this. It was thought at first that a certain amount of hydrogen chloride, as well as carbon dioxide, would diffuse into the alkali. Accordingly, ION-phosphoric acid was tried instead of hydrochloric acid, but this did not liberate all the carbon dioxide, even after heating for 24 hr. at 1500....

case that brought down South Korean stem cell researcher Hwang Woo Suk early this year”. The Los Angeles Times editorial page bemoaned that, “Science took an unnecessary leap forward Wednesday,” by attempting to find a technological fix to address political and religious objections to stem-cell research. “It’s an impressive advance, but scientists — and society — would be better off if they cou...
متن کاملApoplastic synthesis of nitric oxide by plant tissues.
Nitric oxide (NO) is an important signaling molecule in animals and plants. In mammals, NO is produced from Arg by the enzyme NO synthase. In plants, NO synthesis from Arg using an NO synthase-type enzyme and from nitrite using nitrate reductase has been demonstrated previously. The data presented in this report strongly support the hypothesis that plant tissues also synthesize NO via the nonen...
