The American Naturalist, 1930
NATICA or the naticoici type holds a unique place in the ontogeny and phylogeny of the coiled Gastropoda. Its position in the history of the race has been admirably pointed out by Grabau1 in his " Studies of Gastropocla," and in his treatise on the "Phylogeny of Fusus and Its Allies. "9 There would be little cause at this time to take up the discussion

'Radicle' biochemistry: the biology of root-specific metabolism
Trends in Plant Science, 1999The roots of higher plants are a fascinating and largely unexplored biological frontier. One of their features is the ability to synthesize a remarkable diversity of secondary metabolites, and to adjust their metabolic activities in response to biotic and abiotic stress.

Probes for Detection of Free Radicles
2020Reactive species are reactive molecules, having one or two lone pairs that are naturally generated in biological environment via endogenous and exogenous method. These are non-avoidable by-product, highly reactive which are mainly produced by the Electron Transport Chain (ETC) of mitochondria by aerobic respiration.

Growth Movements of the Radicle of Striga
Nature, 1960THE directional growth of the radical (haustorium) of the root parasite Striga asiatica (= S. lutea) is normally controlled by a chemotropic factor diffusing from the host plant root1. The parasite seeds may be germinated by treatment with a solution in which the host roots (Sorghum vulgare, etc.) have been growing. In this case the radicle undergoes a

The Analogy between Radicles and Elements
Nature, 1915THE remarkable chemical analogy of the ammonium radicle and the alkali metals may be explained with the help of Bohr's theory of atomic structure. According to Bohr, the atom of nitrogen consists of a nucleus with a positive charge of 7e, surrounded by two rings of electrons, the inner containing 4, the outer 3 electrons.

Distribution of Vitamin C in the Tip of the Broad Bean Radicle
Nature, 1951IT was stated in an earlier communication1 that if 4-mm. portions of the broad bean radicle were assayed for vitamin C, the ninth portion from the tip contained an average of 112.96 mgm. of the vitamin per 100 gm. of fresh weight. This amount was thought to be present within the region of maximum growth. Following this statement, J. Read pointed out to

GRAFTING IN SEEDS, RADICLES, HYPOCOTYLS AND EPICOTYLS OF CHESTNUT
Acta Horticulturae, 2009Grafts of chestnut can be done on germinated seeds, the radicle of germinated seeds, and the hypocotyls and epicotyls. These grafting methods offer several advantages over conventional field grafting, including: no need for stock trees, grafting can be done indoors, timing is not critical and scions that have a small diameter can be used. In this study,
