Unreported aspects in the sexual cycle of the marine dinoflagellate Lingulodinium polyedrum (Stein) Dodge were described. Our observations included the description of two types of hypnozygote formation, because culture planozygotes were observed to encyst in two different ways: an ecdysal sexual stage or a spiny resting cyst. Phosphate deficiency was the main nutritional condition required for fusing gamete pairs to form resting cysts, whereas replete conditions prevented their appearance and… 

NUCLEAR FEATURES AND EFFECT OF NUTRIENTS ON GYMNODINIUM CATENATUM (DINOPHYCEAE) SEXUAL STAGES 1

TLDR
The nuclear development of the cells during the sexual cycle and the effect of different nitrate and phosphate external levels on sexual stages were studied and suggested an uncoordinated meiosis in both encysting and non‐encysting zygotes.

MULTIPLE ROUTES OF SEXUALITY IN ALEXANDRIUM TAYLORI (DINOPHYCEAE) IN CULTURE 1

TLDR
A flow cytometry analysis showed that sexual induction and zygote formation were very fast and highly common processes, zygotes being nearly half of the population at days 3 and 5 after the induction of sexuality in the cultures.

Revision of the life cycle of the harmful dinoflagellate Margalefidinium polykrikoides (Gymnodiniales, Dinophyceae) based on isolates from Korean coastal waters

TLDR
The resting cyst of M. polykrikoides had a distinct germination process, and asexual and sexual life stages, and the mating behavior of the vegetative cells using a microscope equipped with high-resolution time-lapse digital camera.

Sexual processes and life cycle transitions of the tropical Pacific Alexandrium minutum (Dinophyceae)

Resting cysts of harmful marine dinoflagellates, including Alexandrium species, play an important role in their bloom dynamics, where massive cyst germination is regarded as the natural phenomenon

New life-cycle stages of Gymnodinium catenatum (Dinophyceae): laboratory and field observations

TLDR
The lack of a dormancy period in the sexual resting stage indicated that the advection of off- shore populations shoreward, rather than 'seed beds', is the main mechanism explaining G. catena- tum bloom formation in the Galician rias.

Life cycle stages and evidence of sexual reproduction in the marine dinoflagellate Prorocentrum minimum (Dinophyceae, Prorocentrales).

TLDR
The life cycle of P. minimum was investigated and sexual reproduction in culture was described for the first time, and changes in the DNA content were confirmed by quantitative image cytometry.

EFFECTS OF PARENTAL FACTORS AND MEIOSIS ON SEXUAL OFFSPRING OF GYMNODINIUM NOLLERI (DINOPHYCEAE) 1

TLDR
The regulation of the sexual processes by a multiple loci system is discussed based on the pattern of inheritance of the dormancy period and the number of sexual recombination events recorded within cultures with self‐CP capability.

Comparative study of the life cycles of Alexandrium tamutum and Alexandrium minutum (Gonyaulacales, Dinophyceae) in culture 1

TLDR
In both species, cyst appearance needed to be explained by the existence of more than two sexual types (+/–), which indicates a complex heterothallic mating type, however, planozygotes of both species may divide instead of encysting.

TLDR
This study revealed many similarities between the sexual stages and life cycle pattern of G. nolleri and the related G. catenatum and the existence under culture conditions of an alternative cycle between vegetative cells and zygotes without a hypnozygote stage.

Morphological development of resting cysts in cultures of the marine dinoflagellate Lingulodinium polyedrum (= L. Machaerophorum)

TLDR
The previously undescribed morphological development of resting cysts of the living marine dinoflagellate Lingulodinium ("Gonyaulax") polyedrum has been observed in laboratory cultures and planozygotes preparing to encyst showed a distinctive interstice in the peripheral cytoplasm and often displayed a characteristic swimming behavior.
