Plant Infertility
|
D051479 |

Plant Lectins
|
D037121 |
[Protein or glycoprotein substances of plant origin that bind to sugar moieties in cell walls or membranes. Some carbohydrate-metabolizing proteins (ENZYMES) from PLANTS also bind to carbohydrates, however they are not considered lectins. Many plant lectins change the physiology of the membrane of BLOOD CELLS to cause agglutination, mitosis, or other biochemical changes. They may play a role in plant defense mechanisms.

Plant Necrosis and Chlorosis
|
D000084483 |
[Plant diseases affecting mostly leaves where either plant cells or tissues are dead and/or collapsed (necrosis) or yellowed due to loss of CHLOROPHYLL (chlorosis).

|
Plant Nectar
|
D057048 |
[Sugar-rich liquid produced in plant glands called nectaries. It is either produced in flowers or other plant structures, providing a source of attraction for pollinating insects and animals, as well as being a nutrient source to animal mutualists which provide protection of plants against herbivores.

Plant Poisoning
|
D010939 |
[Poisoning by the ingestion of plants or its leaves, berries, roots or stalks. The manifestations in both humans and animals vary in severity from mild to life threatening. In animals, especially domestic animals, it is usually the result of ingesting moldy or fermented forage.

Plant Root Cap
|
D018518 |
[A cone-shaped structure in plants made up of a mass of meristematic cells that covers and protects the tip of a growing root. It is the putative site of gravity sensing in plant roots.
