• Premise of the study: Land‐plant plastid genomes have only rarely undergone significant changes in gene content and order. Thus, discovery additional examples adds power to tests for causes such genome‐scale structural changes. Methods: Using next‐generation sequence data, we assembled genome saguaro cactus probed nuclear transferred genes functionally related genes. We combined these results with available data across Cactaceae seed plants more broadly infer history loss assess strength...
Significance Convergent and parallel evolution (homoplasy) is widespread in the tree of life can obscure evidence about phylogenetic relationships. Homoplasy be elevated genomes because individual loci may have independent evolutionary histories different from species history. We sequenced five cacti, including iconic saguaro Sonoran Desert three other columnar to investigate whether previously uncharacterized features genome might explain long-standing challenges understanding cactus...
Background and AimsFlowering phenology is a critical life-history trait that influences reproductive success. It has been shown genetic, climatic other factors such as plant size affect the timing of flowering its duration. The spatial temporal variation in columnar cactus Stenocereus thurberi association with environmental cues was studied.
Premise of research. Biotic interactions have long been considered to be less importance in structuring desert systems than other ecosystem types, but biotic often play a critical role meeting the challenges posed by extreme conditions environments. The Sonoran Desert, particular, is home several textbook examples mutualisms, such as between iconic saguaro cactus and its bat pollinators. But what do we know about diversity, ecology, evolution plant-animal, plant-plant, plant-microbe their...
Bats are the main pollinators and seed dispersers of Stenocereus thurberi, a xenogamous columnar cactus northwestern Mexico good model to illustrate spatial dynamics gene flow in long-lived species. Previous studies this showed differences among populations type abundance pollinators, timing flowering fruiting. In study we analyzed genetic variability population differentiation populations. We used three primers ISSR analyze within variation from eight widely separated S. thurberi Sonora,...
• Premise of the study: It has been proposed that species columnar cacti from dry tropical areas depend on bats for their reproduction, whereas subtropical are also pollinated by other species. To test this hypothesis, we examined effects pollinator guild and variation in time space reproductive success a widespread Methods: Changes fruit set, seed activity through were recorded three widely separated populations Stenocereus thurberi . Breeding system sources pollination limitation...
The saguaro cactus is an iconic species of the Sonoran Desert. Its individual growth rates have been investigated for over 100 years. dynamics studied using phenomenological models intended to estimate growth, but not understand underlying biological processes. Most studies suggested summer rainfall as sole factor determining overlooking influence other factors related process growth.We analyzed annual 13 populations in Desert nonlinear models. These are better suited analyze since they...
Genetic differentiations and phylogeographical patterns are controlled by the interplay between spatial isolation gene flow. To assess extent of flow across an oceanic barrier, we explored effect separation peninsula Baja California on evolution mainland peninsular populations long-lived columnar cactus Stenocereus thurberi . We analyzed twelve throughout OPC distribution range to genetic diversity structure using chloroplast DNA sequences. was higher ( H d = 0.81), lower G ST 0.143) in vs...
