Data from: A strong east-west Mediterranean divergence supports a new phylogeographic history of the carob tree (Ceratonia siliqua, Leguminosae) and multiple domestications from native populations
Aim: Phylogeography of fruit trees is challenging due to the recurrent exchanges between domesticated and wild populations. Here we tested the eastern refugium hypothesis (ERH) for the carob tree, Ceratonia siliqua, which supports its natural and domestication origins in the Eastern Mediterranean and a feral origin in the West. Location: Mediterranean basin Taxon: Ceratonia siliqua L., Leguminosae Methods: Divergence time of the divergence between the carob tree and its sister species (C. oreothauma) was estimated based on two nuclear and one plastid sequences. Variation from four plastid regions and 17 nuclear microsatellite loci were used to decipher genetic structure in the carob tree and to test coalescent-based models by an Approximate Bayesian Computation (ABC) approach. We assessed our hypotheses by examining palaeobotanical records and hindcasting the past distribution of the carob tree at the Mid-Holocene, Last Glacial Maximum (LGM) and Last Interglacial (LIG) using species distribution modelling (SDM). Results: The split between C. oreothauma and C. siliqua was estimated at 6.4 Ma, and a first divergence within C. siliqua at 1.3 Ma. After a presence since the Oligocene, Ceratonia was found in the Western and the Eastern Mediterranean in the fossil records during the Pleistocene. Plastid and nuclear markers, characterized by low allelic richness, revealed a strong west-east genetic structuring. Approximate Bayesian computation (ABC) analyses rejected the ERH. Main conclusions: Our study supports a severe population decline during LIG. The strong west-east divergence and the occurrence of four lineages within C. siliqua provided support for a new hypothesis of multiple domestications of the carob tree from native populations throughout the Mediterranean basin.
Data for: Assessing the biodiversity and the impact of pollinators on carob production
<p>As the current climate crisis intensifies, drought-resistant crops are becoming more important due to their ability to withstand the increasingly hotter and drier summers. Such crops are valuable for pollinators as they provide food resources for wild and managed species. The carob tree (<em>Ceratonia</em> <em>siliqua</em> L.) represents an example of a heat- and drought-resistant crop, able to grow in dry areas with practically no inputs. The current study assessed over two growing seasons the diversity of wild bees and other pollinators relying on carob flowers, as well as the contribution of animal pollination to carob production. Carob flowers were subjected to two treatments: Open pollination, where inflorescences were left untreated, and wind pollination, where inflorescences were bagged in a mesh during blooming. Weekly observations during blooming showed that <em>Apis</em> <em>mellifera</em> was the most frequent floral visitor followed by wild bees and wasps. Carob flowers were visited by at least 10 different wild bee species. Open-pollinated flowers produced significantly more pods, with the benefit ranging from 4 to 16 times higher production, depending on the region. Open pollination led to pods with greater weight, length and number of seeds compared to pods derived from wind pollination. The results of the current study highlight the importance of animal pollination to carob production, as well as the significance of carob trees to wild bee conservation.</p>
