Globally, a substantial proportion of existing indigenous and naturalized foods are often neglected thereby narrowing the food-base available to humans. The current study explored the use and contribution of indigenous and naturalized plants to the households’ food-pool among 12 communities in the North West Province of South Africa. An ethnobotanical survey was conducted among 133 rural households across the 12 selected communities from the four district municipalities in North West Province, South Africa. We analyzed the utilization patterns for 31 selected indigenous and naturalized plants (grains, fruits, and vegetables) among the 133 households using two ethnobotanical indices. In reference to the checklist of 31 plants, the sampled households utilize approximately 94% (29) as staple foods, beverages, fruits and fodder. Sorghum bicolor, Vigna unguiculata, Amaranthus sp., Sclerocarya birrea, Persea americana, and Mimusops zeyheri were among the top-six plants based on the Relative Frequency of Citation (RFC, 40–83%). In terms of the different crop-types, Sorghum bicolor (grain), Amaranthus sp. (vegetable), and Sclerocarya birrea (fruit) were the top-ranked plants based on the Species Popularity Index (SPI, 0.53–0.83) among the participants. Overall, there is a need for a renaissance of indigenous and naturalized plants, which has the potential to encourage rural farmers to further embrace the cultivation of these plants on a larger scale so as to enhance food security in the rural communities.

“…However, photographs of living specimens do provide additional insights especially when exact locality, date, and time information is included, and photos showcase three dimensional aspects not captured in the pressing process. Some herbaria have even begun integrating photography into their collections to facilitate this new source of information (Gómez-Bellver et al, 2019; Heberling et al, 2019; Heberling & Isaac, 2018).…”

Following the switch to remote online teaching in the wake of the COVID-19 pandemic, the plant taxonomy course at the University of Georgia (UGA) switched to iNaturalist for the specimen collection portion of the course requirements. Building off extant rubrics, the instructors designed project guidelines for a fully online plant collection experience to alleviate plant awareness disparity. Researchers collected stratified samples from the UGA iNaturalist project along with four other institutions projects to determine if rubrics and project guidelines could improve the quality of observations to make them useful in plant science research. The specific rubric was shown to improve quality of iNaturalist observations. Researchers found that iNaturalist increased engagement as a student-centered tool but did not enhance their manual keying skills as the app uses automatic identification. Instructors recommend continuing to use iNaturalist to supplement physical collection and keying along with a detailed rubric and guidelines for collection.

“…Pooling tissues from multiple individuals from a seed population is inadvisable. For an individual without enough tissue for an experimental material as well as a voucher specimen, a photo voucher can be an alternative choice 53 . Phylogenetic analysis of additional reliable reference sequences of nuclear DNA from voucher specimens with morphological diagnostic characters would allow correct species identification for these original seed populations and inbred lines of the Medicago HapMap project.…”

Plastid phylogenomics uncovers multiple species in Medicago truncatula (Fabaceae) germplasm accessions

Medicago truncatula is a model legume that has been extensively investigated in diverse subdisciplines of plant science. Medicago littoralis can interbreed with M. truncatula and M. italica; these three closely related species form a clade, i.e. TLI clade. Genetic studies have indicated that M. truncatula accessions are heterogeneous but their taxonomic identities have not been verified. To elucidate the phylogenetic position of diverse M. truncatula accessions within the genus, we assembled 54 plastid genomes (plastomes) using publicly available next-generation sequencing data and conducted phylogenetic analyses using maximum likelihood. Five accessions showed high levels of plastid DNA polymorphism. Three of these highly polymorphic accessions contained sequences from both M. truncatula and M. littoralis. Phylogenetic analyses of sequences placed some accessions closer to distantly related species suggesting misidentification of source material. Most accessions were placed within the TLI clade and maximally supported the interrelationships of three subclades. Two Medicago accessions were placed within a M. italica subclade of the TLI clade. Plastomes with a 45-kb (rpl20-ycf1) inversion were placed within the M. littoralis subclade. Our results suggest that the M. truncatula accession genome pool represents more than one species due to possible mistaken identities and gene flow among closely related species.
