| phytohemagglutinin | A phytomitogen from plants that agglutinates red blood cells. The term is commonly used specifically for the lectin obtained from the red kidney bean (Phaseolus vulgaris) which is also a mitogen that stimulates T lymphocytes more vigorously than B lymphocytes. Synonym: phytolectin. (05 Mar 2000) |
| phytohemagglutinins | Mucoproteins isolated from the kidney bean (phaseolus vulgaris); some of them are mitogenic to lymphocytes, others agglutinate all or certain types of erythrocytes or lymphocytes. They are used mainly in the study of immune mechanisms and in cell culture. (12 Dec 1998) |
| phytohormone | <plant biology> Substances that, at low concentration, influence plant growth and differentiation. Formerly referred to as plant hormones or phytohormones, these terms are now suspect because some aspects of the hormone concept, notably action at a distance from the site of synthesis, do not necessarily apply in plants. Also called plant growth regulators. The major classes are absicisic acid, auxin, cytokinin, ethylene and gibberellin, others include steroid and phenol derivatives. (31 Dec 1997) |
