“…It has 2n=14 chromosome and includes two median (m) and five submedian (sm) chromosomes ( Current data demonstrated that the karyotype formula of L. peltata is 1m+6sm, the karyotype formula of L. iberia is 3m+4 sm and the karyotype formula of L. canescens is 2m+ 5sm. However, Ozcan et al [10] findings regarding the karyotype formula conflicted with the present study. They found that three Lallemantia species had a karyotype formula of 6m+1sm [10].…”

“…However, Ozcan et al [10] findings regarding the karyotype formula conflicted with the present study. They found that three Lallemantia species had a karyotype formula of 6m+1sm [10]. Also, Dolatyari and Kamrani [25] showed that various Lallemantia species including L. iberica, L. canescens and L. peltata have 2n=2x=14 chromosomes.…”

“…Also, the present study determined that Lallemantia species are 2A based on Stebbins classification. However, Ozcan et al [10] demonstrated that L. canescens and L. iberica are 2A whereas L. peltata are 2B according to the Stebbins classification. In addition, the scatter diagram based on A1 and A2 showed that Lallemantia species exhibited close localisation (Figure 4).…”

The study aimed to karyologically analyse three species [(Lallemantia peltata (L.) Fisch. & Mey., Lallemantia iberica (Bieb.) Fisch. & Mey. and Lallemantia canescens (L.) Fisch. & Mey.)] from Lallemantia Fisch. & C.A.Mey. (Lamiaceae) grown in Turkey. Also, it was calculated various karyotype asymmetry and S/AI, CVCL and MC values in this study. Seed samples were given natural habitats and Feulgen staining method was used. The study showed that the chromosome numbers of Lallemantia species are 2n=14 and that they have median (m) and submedian (sm) centromeric chromosomes. The study also demonstrated karyotype analysis and asymmetry values and suggested that three species of Lallemantia genus were 2A based on Stebbins classifications. Furthermore, the study showed Pearson correlation using karyotype asymmetry values and a scatter diagram was formed using A1 and A2. The results obtained from the study were compared with the results of karyotype analysis performed by different literatures and it was concluded that there may be differences according to locality.

The traditional karyotype studies are widely used in plant systematics to evaluate the positions of species. However, studies sometimes can not solve systematic problems. In recent years, computer-based systems have gained importance in contributing to the solution of the taxonomical problems. The aim of this study was to identify three Lallemantia species by using the LBP (local binary pattern) texture operator based on chromosome images in mitosis. LBP is the one of the most powerful and easily applicable tool for identifying local image patterns. In this study, microphotographs of 641 cells in the metaphase stage of mitosis were used. The LBP involves preprocessing, feature extraction, feature selection, and classification. Decision tree (DT), linear discriminant (LD), support vector machine (SVM), K-nearest neighbor (KNN), bagged tree (BT) and ensemble subspace nearest neighbor (SNN) were used in the classification stage. This study found that the best acting classifier was SNN because achievement rate was one hundred percent. Also, a dendrogram was formed to measure the similarity among the three species. As a result, LBP can be accepted as a tool for classifying plants by using chromosome images.
