A hardy grain crop, rye, grown in northern climates. It is the most frequent host to ergot (CLAVICEPS), the toxic fungus. Its hybrid with TRITICUM is TRITICALE, another grain.

A genus of ascomycetous fungi, family Clavicipitaceae, order Hypocreales, parasitic on various grasses (POACEAE). The sclerotia contain several toxic alkaloids. Claviceps purpurea on rye causes ergotism.

Complex nucleoprotein structures which contain the genomic DNA and are part of the CELL NUCLEUS of PLANTS.

Chitinase is an enzyme that catalyzes the hydrolysis of chitin, a polysaccharide that makes up the exoskeleton of insects and the cell walls of fungi, into simpler sugars.

Seeds from grasses (POACEAE) which are important in the diet.

A plant genus of the family POACEAE that is the source of EDIBLE GRAIN. A hybrid with rye (SECALE CEREALE) is called TRITICALE. The seed is ground into FLOUR and used to make BREAD, and is the source of WHEAT GERM AGGLUTININS.

Deoxyribonucleic acid that makes up the genetic material of plants.

The encapsulated embryos of flowering plants. They are used as is or for animal feed because of the high content of concentrated nutrients like starches, proteins, and fats. Rapeseed, cottonseed, and sunflower seed are also produced for the oils (fats) they yield.

Proteins found in plants (flowers, herbs, shrubs, trees, etc.). The concept does not include proteins found in vegetables for which VEGETABLE PROTEINS is available.
