On root posets for noncrystallographic root systems [PDF]

Mathematics of Computation, 2014
We discuss properties of root posets for finite crystallographic root systems, and show that these properties uniquely determine root posets for the noncrystallographic dihedral types and type H 3 H_3 , while proving that there does not exist a poset satisfying all of the properties in type H 4

"GALVANOTROPISM" OF ROOTS [PDF]

Journal of General Physiology, 1927
1. New experiments, made in such a way to eliminate as completely as possible products of polarization and the migration of such products when formed, have shown that the exhibition of galvanotropic curvature in roots is mainly dependent upon such products, since no curvature appears when they are excluded. 2.

Phenotypic Approaches to Drought in Cassava: Review

Frontiers in Physiology, 2013
Cassava is an important crop in Africa, Asia, Latin America and the Caribbean. Cassava can be produced adequately in drought conditions making it the ideal food security crop in marginal environments. Although cassava can tolerate drought stress, it can

Genome-wide identification and expression analysis of the citrus calcium-dependent protein kinase (CDPK) genes in response to arbuscular mycorrhizal fungi colonization and drought

Biotechnology & Biotechnological Equipment, 2020
The calcium-dependent protein kinases (CDPKs, also termed CPKs) are a large, diverse protein family that play significant roles in biotic and abiotic stress responses in plants.
