Meiotic chromosomal studies in family Zygophyllaceae R. Br. from Rajasthan
TLDR
Four genera and 5 species belonging to family Zygophyllaceae collected from various localities of Rajasthan have been cytologically worked out for the first time from India and the presence of B-chromosomes makes the first report of the species from world level.Abstract:
Present paper deals with the cytomorphological study of 4 genera and 5 species belonging to family Zygophyllaceae collected from various localities of Rajasthan. Three cytomorphovariants of Tribulus terrestris have been observed with 2n=24, 36 and 48. Peganum harmala with 2n=12 (based on x=6) is reported for the first time from world level, earlier the species is based on x=12. The presence of B-chromosomes also makes the first report of the species from world level. Fagonia cretica (2n=22), Tribulus alatus (2n=24) and Zygophyllum simplex (2n=16) have been cytologically worked out for the first time from India.read more

TL;DR: Parsimony analysis of nucleotide sequences of the plastid gene rbcL and non-coding trnL-F region was used to examine phylogenetic relationships of 36 members of Zygophyllaceae, especially of the four genera forming subfamily Zygophicallloideae.

Size and Alkaloid Content of Seeds in Induced Autotetraploids of Datura innoxia, Datura stramonium and Hyoscyamus niger
TL;DR: The increased size and alkaloid content makes tetraploid seeds of Datura innoxia, D. stramonium and Hyoscyamus niger a better source of alkaloids than diploid Seeds.
