Transcriptomic Analysis Reveals the Regulation Mechanism of Sporogenesis in Ulva prolifera

open access: yesFrontiers in Marine Science, 2022
Ulva prolifera, the main causative species of green tide, has drawn much attention. Spore reproduction was one of the main reproduction strategies that could be induced by changing environmental factors, but the mechanism of spore formation remains ...

Origin of the Diplazium hachijoense complex (Athyriaceae) [PDF]

open access: yesPhytoKeys, 2019
We analyzed the phylogeny of the Diplazium hachijoense complex using plastid trnL-F and low-copy nuclear marker AK1 DNA sequences. Based on allele constitution, triploid apogamous species of the D. hachijoense complex appeared to have originated from the

Cytoembryological aspects of reduced seed setting in Ranunculus ficaria L. subsp. bulbifer (Marsden-Jones) Lawalrée

open access: yesActa Societatis Botanicorum Poloniae, 2014
Highly disturbed micro- and macro-sporogenesis in R. ficaria L. subsp. bulbifer gives rise to cytologically and genetically unbalanced reproductive cells. In plants from different papulatians, pollen degenerates in various percentages.
