The Diversity and Dynamics of Sex Determination in Dioecious Plants

open access: yesFrontiers in Plant Science, 2021
The diversity of inflorescences among flowering plants is captivating. Such charm is not only due to the variety of sizes, shapes, colors, and flowers displayed, but also to the range of reproductive systems. For instance, hermaphrodites occur abundantly

The Ethylene Biosynthesis Gene CpACO1A: A New Player in the Regulation of Sex Determination and Female Flower Development in Cucurbita pepo

open access: yesFrontiers in Plant Science, 2022
A methanesulfonate-generated mutant has been identified in Cucurbita pepo that alters sex determination. The mutation converts female into hermaphrodite flowers and disrupts the growth rate and maturation of petals and carpels, delaying female flower ...

Reproductive biology of two Lagenaria (Curcubitaceae) species

open access: yesBotanica, 2022
The genus Lagenaria (Cucurbitaceae) members are underutilised, neglected and on the verge of being threatened to extinction. An investigation of their reproductive biology will serve as the basis for effective strategic planning towards their ...

Macroevolutionary patterns in the Aphidini aphids (Hemiptera: Aphididae): diversification, host association, and biogeographic origins. [PDF]

open access: yesPLoS ONE, 2011
Due to its biogeographic origins and rapid diversification, understanding the tribe Aphidini is key to understanding aphid evolution. Major questions about aphid evolution include origins of host alternation as well as age and patterns of diversification

Male reproductive success is not strongly affected by phenological changes in mate availability in monoecious Sagittaria latifolia

open access: yesRoyal Society Open Science, 2023
Many plants express their female and male sex roles at different times (dichogamy), with important consequences for mating. Dichogamy can yield mate limitation via biased floral sex ratios, particularly at the beginning and end of the flowering season ...

Sex expression in Serbian dendroflora: A case study of Fraxinus ornus var. angustifolia [PDF]

open access: yesArchives of Biological Sciences, 2012
Out of a total number of tree species in Serbian flora, 28% are hermaphrodites, 43% are monoecious and 29% are dioecious. The dendroflora appears to have a larger proportion of unisexual than hermaphrodite species.

Default Sex and Single Gene Sex Determination in Dioecious Plants

open access: yesFrontiers in Plant Science, 2020
A well-established hypothesis for the evolution of dioecy involves two genes linked at a sex-determining region (SDR). Recently there has been increased interest in possible single gene sex determination.

The Andromonoecious Sex Determination Gene Predates the Separation of Cucumis and Citrullus Genera. [PDF]

open access: yesPLoS ONE, 2016
Understanding the evolution of sex determination in plants requires the cloning and the characterization of sex determination genes. Monoecy is characterized by the presence of both male and female flowers on the same plant. Andromonoecy is characterized

Evolutionary lability of a complex life cycle in the aphid genus Brachycaudus

open access: yesBMC Evolutionary Biology, 2010
Background Most aphid species complete their life cycle on the same set of host-plant species, but some (heteroecious species) alternate between different hosts, migrating from primary (woody) to secondary (herbaceous) host plants.

Mapping a Partial Andromonoecy Locus in Citrullus lanatus Using BSA-Seq and GWAS Approaches

open access: yesFrontiers in Plant Science, 2020
The sexual expression of watermelon plants is the result of the distribution and occurrence of male, female, bisexual and hermaphrodite flowers on the main and secondary stems. Plants can be monoecious (producing male and female flowers), andromonoecious
