Polyploidization is important for the speciation and subsequent evolution of many plant species. Analyses of the duplicated genes produced via polyploidization events may clarify the origin and evolution of gene families. During terpene biosynthesis, 3-hydroxy-3-methylglutaryl coenzyme A synthase (HMGS) functions as a key enzyme in the mevalonate pathway. In this study, we first identified a total of 53 HMGS genes in 23 land plant species, while no HMGS genes were detected in three green algae species. The phylogenetic analysis suggested that plant HMGS genes may have originated from a common ancestral gene before clustering in different branches during the divergence of plant lineages. Then, we detected six HMGS genes in the allotetraploid cotton species (Gossypium hirsutum), which was twice that of the two diploid cotton species (Gossypium raimondii and Gossypium arboreum). The comparison of gene structures and phylogenetic analysis of HMGS genes revealed conserved evolution during polyploidization in Gossypium. Moreover, the expression patterns indicated that six GhHMGS genes were expressed in all tested tissues, with most genes considerably expressed in the roots, and they were responsive to various phytohormone treatments and abiotic stresses. The sequence and expression divergence of duplicated genes in G. hirsutum implied the sub-functionalization of GhHMGS1A and GhHMGS1D as well as GhHMGS3A and GhHMGS3D, whereas it implied the pseudogenization of GhHMGS2A and GhHMGS2D. Collectively, our study unraveled the evolutionary history of HMGS genes in green plants and from diploid to allotetraploid in cotton and illustrated the different evolutionary fates of duplicated HMGS genes resulting from polyploidization.

Plants of allotetraploid cotton, Gossypium hirsutum L. (2n = 4x = 52), which are monosomic for chromosome 9 or haplodeficient for the long arm of the chromosome, an Ah genome chromosome, produce a high frequency of aneuploid progeny. The aneuploids include monosomes, trisomes, and multiple monosomic and trisomic combinations that are the result of chromosome nondisjunction, which is induced by the deficiency of the long arm of chromosome 9. Loss of chromosomes occurs far more frequently than additions, and chromosomes of the Ah genome undergo nondisjunction at a significantly greater rate than do chromosomes of the Dh genome. Stained paraffin sections of ovules at different stages of development of monotelodisomic 9 and normal plants (TM1) were analyzed to determine the time and probable causes of nondisjunction during megasporogenesis. The most significant difference between mono 9 and TM1 was observed in ovules in stages of development just before and at the time of flowering. The mono 9 female gametophytes had supernumerary nuclei, indicating that chromosome nondisjunction occurs at the mitotic divisions of the embryo sac.Key words: chromosome nondisjunction, aneuploids, megasporogenesis, cotton, Gossypium hirsutum cytogenetics.
