The evolution of dioecy and herbicide resistance: a genomic and transcriptomic exploration of Amaranthus species
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2023-12-04 without embargo terms

Understanding the genetic basis of dioecy in waterhemp (Amaranthus tuberculatus) and palmer amaranth (Amaranthus palmeri)
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2022-05-01

Evolution of gynodioecy and dioecy: theoretical issues and the case of Bidens sandvicensis and B. cervicata
… populations, resulting in the evolution of subdioecy or dioecy. Conditions for the evolution of subdioecy from two classes of nucleo-cytoplasmic gynodioecy are found to be similar to, and in some cases less stringent than, those required for evolution of sub dioecy from nuclear gynodioecy. …

Recent advances using genetic analyses in waterhemp
… such as non-target-site herbicide resistance and dioecy, may contribute to the advancement of effective management strategies. Inheritance, segregation, and linkage mapping of non-target-site resistance was conducted in two A. tuberculatus populations, one from Illinois and the other from …

Understanding gender determination in dioecious Amaranthus weeds palmer amaranth (Amaranthus palmeri) and waterhemp (Amaranthus tuberculatus)
… is known, however, about the genetic basis of dioecy in Amaranthus species. Understanding dioecy in these weeds can help us in establishing a probable control strategy for both weeds. Thus, the major aim of this study is to identify the mechanism of sex-determination in both these weedy …

Characterization of the sex chromosomes in spinach
… autosomes of hermaphroditic species to maintain dioecy. The major barriers to sex chromosome characterization have been the inherent difficulties of working with a non-recombining sex determining region that make sequencing and mapping the Male-Specific region of the Y chromosome (MSY) …

Dissecting the evolutionary forces shaping sex chromosome evolution in papaya
… in papaya. Despite separate breeding systems of dioecy and gynodioecy, the X chromosomes are highly similar and cluster into a single group. This contrasts the two sub groups (gynodioecy and dioecy) observed in the autosome and three sub groups observed in the Y. The X chromosome has a tenfold …

Characterization of the hermaphroditic reproductive system and sexual development in the planarian Schmidtea mediterranea
… can drive the transition from hermaphroditism to dioecy.

Phenology and branching in eight selected species of the genus Cliffortia
… of sexuality, led to the prevalent acceptance of dioecy as the norm for the genus, while in truth, it is monoecy with dichogamy in this genus, as in many other wind-pollinated taxa.
-
Molecular analysis of sex chromosome evolution in papaya
… size differences between sexes suggest the dioecy seen in some Vasconcellea species and one Jacaratia species may be the result of independently evolved sex chromosomes, a finding that would be interesting to pursue in the future.

Dioecious Plants: Evolution And Sex Ratio And Asepen Decline
<p>Although dioecious species are rare in nature, the sexual system appears in a diverse number of families and across all life forms and global locations. We looked at the population dynamics of natural populations to determine why many dioecious populations display biased sex ratios. We also …

Female sterility and carpel development in plants
… of different sex types in plants. Stable dioecy results when the two functional genes affecting carpel and stamen development are linked in close proximity and their recessive alleles are linked in repulsion phase. The relatively low frequency of female sterile mutants in nature is …

Resolution of sex chromosomes in waterhemp and Palmer amaranth
