Abstract

The systematic relationships of Krameriaceae have changed considerably. The phylotranscriptomic data sets provide highly informative data for resolving deeper‐level phylogenetic relationships. The phylotranscriptomic analyses to infer evolutionary relationships of Krameriaceae in the order Zygophyllales using the Minimum Evolution, Maximum Parsimony and Maximum Likelihood methods recovered similar topology and taxon proximity. Under the Zygophyllales clade, Krameria lanceolata Torr. of the family Krameriaceae nested with Tribulus eichlerianus K.L. Wilson and Larrea tridentata (Sessé & Moc. ex DC.) Coville belonging to the family Zygophyllaceae with strong nodal support. The phylotranscriptomic analyses suggest that the family Krameriaceae is sister to Zygophyllaceae. Bangladesh J.

Highlights

The order Zygophyllales Link in the Fabids comprises two families viz. Zygophyllaceae R.Br. and Krameriaceae Dumort. (APG IV, 2016)
Wilson and Larrea tridentata (Sessé & Moc. ex DC.) Coville belonging to the family Zygophyllaceae, and Krameria lanceolata Torr. of the family Krameriaceae available in the SRA database from the study of ‘One Thousand Plant Transcriptomes Initiative’ (Leebens-Mack, 2019) were retrieved, and analyzed together with Rhus radicans L., Gleditsia triacanthos L. and Polygala lutea L. as representatives from Anacardiaceae, Fabaceae and Polygalaceae, respectively
The present study revealed the molecular phylogenetic analyses of 10376 parsimony informative sites of Tribulus eichlerianus, Larrea tridentata, Krameria lanceolata, Rhus radicans, Gleditsia triacanthos, Polygala lutea and Tetrastigma obtectum (Fig. 1)

Summary

Introduction

The order Zygophyllales Link in the Fabids comprises two families viz. Zygophyllaceae R.Br. and Krameriaceae Dumort. (APG IV, 2016). The systematic relationships of the Zygophyllaceae and Krameriaceae have often been debatable (APG IV, 2016).
