The micromorphology of several populations of Brassica tournefortii in Egypt was investigated, showing that seed ornamentations can distinguish different morphological forms, and there is a clear correlation between soil variables and identified forms. Fungal species from anthers are related to morphological plasticity of B. tournefortii and ecological factors.
Several populations of Brassica tournefortii (Brassicaceae) occurring in Egypt are investigated from the micromorphological point of view (seed ornamentations). The species is known to show a notable phenotypic plasticity and five morphotypes was identified in the past. Furthermore, a soil analysis as well as a study of the fungal species from anthers were carried out. The aim of the study is to verify the taxonomic value of the morpholotypes of B. tournefortii and their ecologic relationship with soil variables. The results obtained demonstrated that the five morphological forms can be distinguished based on the seed sculpture. The Canonical Correspondence Analysis (CCA) exhibited a clear correlation between the soil variables and the identified forms. Six species of fungi were detected from the ecto-anthers in the Forms (F2-F4), while F1 was lacking the fungal species. The study revealed that the morphological plasticity of studied B. tournefortii depends on ecological factors. (c) 2021 The Authors. Published by Elsevier B.V. on behalf of King Saud University.
