Nodulation is controlled by a variety of processes, both external (heat, acidic soils, drought, nitrate) and internal (autoregulation of nodulation, ethylene). Autoregulation of nodulation controls nodule numbers per plant through a systemic process involving the leaf. Leaf tissue senses the early nodulation events in the root through an ...
Nod factor. The structure of the major Nod factor produced by Sinorhizobium meliloti. Nod factors ( nodulation factors or NF ), are signaling molecules produced by soil bacteria known as rhizobia in response to flavonoid exudation from plants under nitrogen limited conditions. Nod factors initiate the establishment of a symbiotic relationship ...
The partner choice hypothesis proposes that the plant uses prenodulation signals from the rhizobia to decide whether to allow nodulation, and chooses only noncheating rhizobia. There is evidence for sanctions in soybean plants, which reduce rhizobium reproduction (perhaps by limiting oxygen supply) in nodules that fix less nitrogen.
Polyphenol oxidase is an enzyme found throughout the plant and animal kingdoms, including most fruits and vegetables. PPO has importance to the food industry because it catalyzes enzymatic browning when tissue is damaged from bruising, compression or indentations, making the produce less marketable and causing economic loss.
The grass family includes most of the known C 4 species – around 5000. They are only found in subfamilies of the PACMAD clade. Major C 4 crops such as maize, sugarcane, sorghum and pearl millet belong in this family. The only known species with C 3, C 4 and intermediate variants, Alloteropsis semialata, is a grass.
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite. This is in accordance with Justus von ...
Root vegetable. Carrot roots in various shapes and colors. Root vegetables are underground plant parts eaten by humans as food. In agricultural and culinary terminology, the term applies to true roots such as taproots and tuberous roots as well as non-roots such as bulbs, corms, rhizomes, and stem tubers. [1]
New World crops are those crops, food and otherwise, that are native to the New World (mostly the Americas) and were not found in the Old World before 1492 AD. Many of these crops are now grown around the world and have often become an integral part of the cuisine of various cultures in the Old World. Notable among them are the "Three Sisters ...
