Characterization of SSR markers from draft genome assembly and genotypic data in (Zingiberaceae).

The plant family Zingiberaceae consists of many medicinally important tropical herbs. Here, we provide a contig level genome assembly for , one of the medicinally utilized species in this family We used genome assembly to identify candidate Simple Sequence Repeat (SSR) markers in the nuclear, chloroplast and mitochondrial compartments. We identified a total of 60,695 SSRs, which consisted of di-, tri-, tetra-, penta- and complex repeat types, and primers were designed for 14,851 SSR loci from both coding and non-coding parts of the genome.

Evolutionary patterns of variations in chromosome counts and genome sizes show positive correlations with taxonomic diversity in tropical gingers.

Premise: Cytogenetic traits such as an organism's chromosome number and genome size are taxonomically critical as they are instrumental in defining angiosperm diversity. Variations in these traits can be traced to evolutionary processes such as polyploidization, although geographic variations across cytogenetic traits remain underexplored. In the pantropical monocot family Zingiberaceae (~1500 species), cytogenetic traits have been well documented; however, the role of these traits in shaping taxonomic diversity and biogeographic patterns of gingers is not known.

Himalayan orogeny and monsoon intensification explain species diversification in an endemic ginger (Hedychium: Zingiberaceae) from the Indo-Malayan Realm.

The Indo-Malayan Realm is a biogeographic realm that extends from the Indian Subcontinent to the islands of Southeast Asia (Malay Archipelago). Despite being megadiverse, evolutionary hypotheses explaining taxonomic diversity in this region have been rare. Here, we investigate the role of geoclimatic events such as Himalayan orogeny and monsoon intensification in the diversification of the ginger-lilies (Hedychium J.
