Artificial induction of autogamy inParamecium caudatum [PDF]
Genetical Research, 1979 SUMMARYThree methods of artificial induction of autogamy inParamecium caudatumwere described: (1) treatment with KCl+papain, (2) treatment with KCl and then with KCl + papain and (3) ordinary mating reaction and then treatment with papain. As expected, one-to-one segregation ratios were obtained in the progeny from the parents heterozygous for the two ...

Preventing self-fertilization: Insights from Ziziphus species [PDF]
Frontiers in Plant Science, 2023 The fitness of self-progeny individuals is inferior to that of their outcrossed counterparts, resulting in a reduction in a plant population’s ability to survive and reproduce.

Does autogamy contribute to invasion in Lilium formosanum?
South African Journal of Botany, 2008 The Taiwanese geophyte Lilium formosanum is invasive in the eastern parts of South Africa. Although it is capable of autogamy, a pollinator, the hawkmoth Agrius convolvuli, is present. Reproduction may therefore take place both by self- and cross-fertilisation. The relative importance of these modes of pollination for seed production is evaluated using

Floral and pollination biology of dragon fruit reveals strategies for enhancing productivity through pollination management and reproductive window extension [PDF]
Scientific ReportsDragon fruit (Selenicereus undatus (Haw.) D.R. Hunt) is emerging as a high-value crop globally. However, its reproductive biology remains poorly characterized, with conflicting reports ranging from strict self-incompatibility (allogamy) to self ...

Pollination strategy of Gennaria diphylla (Orchidaceae) on the Canary Islands and on Madeira
Mediterranean Botany, 2022 Gennaria diphylla (Link) Parl. is a terrestrial, inconspicuous green orchid. Its distribution includes the central and western Mediterranean region as well as the Canary Islands and Madeira. Investigations on its pollination biology are scarce.

Exchanging Genes Within a City: Analysis of Pollen Flow Patterns in a Narrow Endemic Plant Species Threatened by Urbanisation. [PDF]
Ecol EvolAnthropogenic habitat fragmentation can severely disrupt gene flow in endemic plants that depend on species‐specific native pollinators with limited dispersal ability. Using paternity analysis across fragmented and continuous populations, we found that pollen flow was maintained in intact bushland but was completely absent between fragments separated ...

Study of autogamy in the ciliate euplotes minuta
, 1971 1. Autogamy, or self-fertilisation in the marine ciliate Euplotes minuta has been studied by genetic and cytological means. The naturally occurring, between stock variation in four characters was used to contrast the genetic consequences of both conjugation and autogamy. 2.
