We develop an efficient snapshot algorithm that needs no control messages and does not require channels to be first-in-first-out. We also show that several stable properties (e.g., termination, deadlock) can be detected with uncoordinated distributed snapshots. For such properties, our algorithm can be further simplified.
Isoetes L. is an ancient genus of heterosporous lycopsids with a unique phylogenetic position. Repeated adaptations to environmental changes over time have contributed to occupying a variety of niches in Isoetes. However, we know little about how they adapt to the environmental changes, and the sequence resources are very limited in public databases.… (More)
Crassulacean acid metabolism (CAM) is widespread in terrestrial and aquatic species, plastic in response to environmental changes. Isoetes L. is one of the earliest basal vascular plants and CAM is popular in this genus. Isoetes sinensis Palmer is an amphibious species, alternating frequently between terrestrial and aquatic environments. Given this, we… (More)

Potamogeton is one of the most difficult groups to clarify in aquatic plants, which has an extensive range of interspecific morphological and ecological diversity. Internal transcribed spacer (ITS) is prevalent for phylogenetic analysis in plants. However, most researches demonstrate that ITS has a high percentage of homoplasy in phylogenetic datasets. In… (More)
LEAFY COTYLEDON1 (LEC1) is a HAP3 subunit of CCAAT-binding transcription factor. The species in the genus Isoetes L. from China include I. hypsophila, I. yunguiensis, I. sinensis, I. orientalis, and I. taiwenensis. In this study, we initially gathered substantial samples from wide geographic ranges in China. Then we explored the evolutionary characteristics… (More)
