We have tested the hypothesis that reseeding is a plesiomorphic character state and that sprouting is a derived state inAspalathus linearis, and that the latter is an adaptation to ensure fire-survival in a fireprone environment. Samples of five seeder and four sprouter populations of A.linearis were examined by horizontal starch gel electrophoresis to assess the amount of genetic differentiation within and between sprouting and seeding populations, and to determine the extent of gene flow…

Resprouters Versus Reseeders: Are Wild Rooibos Ecotypes Genetically Distinct?
- Environmental Science, BiologyFrontiers in Genetics
- 2021
The hypothesis that wild rooibos ecotypes are distinct in genetic variability and that the ecotypes found in the Northern Cape are differentiated from those in the Cederberg that may be linked to a fire-survival strategy as well as distinct morphological and phytochemical differences is tested.
Fitness and evolution of resprouters in relation to fire
- Environmental SciencePlant Ecology
- 2011
Seven fitness benefits of post-fire resprouting are noted that centre around the rapid return to adult growth rates and early flowering and seed set without the risks of recruitment failure, indicating that seed plants have had a long evolutionary relationship with fire.

Results suggest that pioneer seeder behavior is largely promoted by wildfires that are, in turn, detrimental to slow-growing, late-sucessional tall shrubs and forest fire hazard risk management can be put into perspective.

Seasonal variation in the nitrogen nutrition and carbon assimilation in wild and cultivated Aspalathus linearis (rooibos tea)
- Biology
- 2014
Wild and cultivated rooibos tea had different methods of adapting to nitrogen (N) nutrition and carbon (C) assimilation during wet and dry seasons, and the wild plants were better able to tolerate summer drought by increased water use efficiency and maintaining higher levels of biological N2 fixation.

The level of genetic diversity maintained within L. latifolius populations, and the level of population divergence found, is strongly influenced by its status as a cultivated garden flower and its humanassociated mode of gene flow via seed dispersal.

In fynbos legumes sprouting and non-sprouting taxa differ in their habitat specificity, population densities, relative regional abundance, and in seed germination tempo, so problems relating to the use of sprouting versus non-Sprouting as a taxonomic character in fyn Bos legumes are addressed and possible solutions are given.
Isozymes and the Analysis of Genetic Structure in Plant Populations
- Biology

Genetic variation in plant populations is distributed nonrandomly, with marked genetic differences occurring over short distances, like the plants themselves, genes and genotypes tend to be clumped.
