Most plants can reproduce both sexually and vegetatively, and the balance between the two reproductive modes may vary widely between and within species. Extensive clonal growth may affect the evolution of life history traits in many ways. First, in some clonal species, sexual reproduction and recru...
Here we investigated a sympatric occurrence of sexual and asexual reproduction in the pineapple mealybug,Dysmicoccus brevipes. This pest invaded southwestern Japan, including Okinawa and Ishigaki Islands, in the 1930s in association with imported pineapple plants. Our recent censuses demonstrated that ...
Six estimates of resource allocation to sexual reproduction (nectar concentration, nectar volume, sugar production, pollinator visitation rates, fruit-set, and seed production) and a single estimate of resource allocation to asexual reproduction (the rate of rooted-branch production) were examined for ...
Phytochromes are important in allowing plants to sense and react to environmental changes. We investigated the similarities and differences of sexual and asexual offspring of a tropical liverwort (Marchantia inflexa). We expected that both types of dispersing offspring will have similar germination respon...
Fungi are thus appropriate organisms for studies of the reasons for the selection of sexuality or clonality and of the mechanisms underlying this selection. Magnaporthe oryzae, an Ascomycete causing blast disease on rice, reproduces mostly asexually in natura. Sexual reproduction is possible in vitro...
The frequency and dynamics of sexual and asexual reproduction were investigated in a dioecious epixylic hepatic, Anastrophyllum hellerianum, which has decl... M Pohjamo,S Laaka-Lindberg - 《Perspectives in Plant Ecology Evolution & Systematics》 被引量: 91发表: 2004年 ...
Molecular and Morphological Data Support the Existence of a Sexual Cycle in Species of the Genus Paracoccidioides (HMG) domain (MAT1-2), led to the identification of the formation of young ascocarps with constricted coiled hyphae related to the initial stage of ... MDM Teixeira,RC Theodoro,...
Sexual reproduction in heterothallic ascomycete fungi is controlled by a single mating-type locus calledMAT1with two alternate alleles or idiomorphs,MAT1-1andMAT1-2. These alleles lack sequence similarity and encode different transcriptional regulators. A large number of phytopathogenic fungi including...
Genetic processes in arbuscular mycorrhizal fungi Arbuscular mycorrhizal (AM) fungi (Glomeromycota) colonize roots of the majority of land plants and facilitate their mineral nutrient uptake. Consequently,... TE Pawlowska - 《Fems Microbiology Letters》 被引量: 94发表: 2010年 AFLP and single-strand...
In Hieracium, the formation of seeds through sexual and apomictic processes differ in two aspects: meiosis is avoided during apomictic female gametophyte formation (apomeiosis), which is controlled by the loss of apomeiosis ( LOA) locus; and embryo and endosperm develop autonomously, a process cont...
