Artificial selection optimizes clonality in chaya (Cnidoscolus aconitifolius)

open access: yesScientific Reports, 2021
The clonal propagation of crops offers several advantages to growers, such as skipping the juvenile phase, faster growth, and reduced mortality. However, it is not known if the wild ancestors of most clonal crops have a similar ability to reproduce ...

Temperature and inoculation method influence disease phenotypes and mortality of Eucalyptus marginata clonal lines inoculated with Phytophthora cinnamomi [PDF]

open access: yes, 2002
Survival of 1-year-old plants of three clonal lines of Eucalyptus marginata (jarrah), two ranked as resistant (RR1 and RR2) and one as susceptible (SS1) to Phytophthora cinnamomi, was assessed after pathogen inoculation with either mycelial mats ...

The human myeloproliferative disorders: molecular pathogenesis and clonal heterogeneity [PDF]

open access: yes, 2010
The classical myeloproliferative disorders (MPD), comprising essential thrombocythaemia (ET), polycythaemia vera (PV) and idiopathic myelofibrosis (IMF), are clonal premalignant haematopoietic neoplasms associated with activating mutations in signalling ...

Clonal Composition of Human Adrenocortical Neoplasms [PDF]

open access: yes, 1994
The mechanisms of tumorigenesis of adrenocortical neoplasms are still not understood. Tumor formation may be the result of spontaneous transformation of adrenocortical cells by somatic mutations.

STORAGE TIME EFFECT ON MINI-CUTTINGS ROOTING IN Tectona grandis LINN F. CLONES

open access: yesRevista Árvore, 2017
The study aimed to evaluate the influence of storage length on Tectona grandis mini-cuttings survival and rooting. A factorial arrangement (4 x 7) was utilized, based on four clones (Carapá, Ipê, GU5 and TB7) and seven time intervals from mini-cuttings ...

Evaluation of resistance to Phytophthora cinnamomi in seed-grown trees and clonal lines of Eucalyptus marginata inoculated in lateral branches and roots [PDF]

open access: yes, 2002
Seed-grown trees and six clonal lines of 3-5-4-5-year-old Eucalyptus marginata (jarrah) growing in a rehabilitated bauxite mine site in the jarrah forest were underbark-inoculated on lateral branches (1995) or simultaneously on lateral branches and ...

Flowering and vegetative propagation of pyrethrum (Chrysanthemum cinerariaefolium Vis.) in vivo and in vitro [PDF]

open access: yes, 1976
The influence of climatic conditions was investigated on flowering behaviour of pyrethrum ( Chrysanthemum cinerariaefolium Vis.). At low temperatures high numbers of plants initiated high numbers of flower heads.

Concurrent Effects of Sediment Accretion and Nutrient Availability on the Clonal Growth Strategy of Carex brevicuspis-A Wetland Sedge That Produces Both Spreading and Clumping Ramets

open access: yesFrontiers in Plant Science, 2017
Clonal plants producing both clumping and spreading ramets can adjust their growth forms in response to resource heterogeneity or environmental stress. They might produce clumping ramets to retain favorable patches, or produce spreading ramets to escape ...

Testing for clonal propagation

open access: yes, 2005
The conceptual basis for testing clonal propagation is reconsidered with the result that two steps need to be distinguished clearly: ( 1) specification of the characteristics of multilocus genotype frequencies that result from sexual reproduction ...
