“…A new edition of the field guide "Key to the Flora of the Czech Republic" was published last year (Kaplan et al 2019a). Several taxonomically complicated groups were revised, and new species (Trávníček et al 2018, Király et al 2019, Lepší et al 2019 and hybrids (Hodková & Mandák 2018, Prančl et al 2018, Popelka et al 2019 were discovered. Additional plant taxa were recorded for the first time in this country, comprising previously unrecognized native ones (Roleček et al 2018, Velebil 2018 as well as introduced aliens (Danihelka 2019a, Lustyk & Doležal 2019.…”

“…Research focused on gene expression and regulation includes hybridization (Hodková & Mandák, 2018 ), phylogenetic (Li et al., 2022 ), and proteomic studies in relation to edaphoclimatic factors where cultivars are grown (Zhao et al., 2022 ). The main objective of genic expression studies has been to find the relationship between the agri‐environmental offer and the genetic variability associated with the greater production of seeds with high contents of vegetable proteins (El‐Hakim et al., 2022 ) and high‐value biocomposites (Campos‐Rodriguez et al., 2022 ).…”

Currently, the demand for healthy consumption and the use of alternatives to dairy proteins for the development of foods with good nutritional value are growing. Quinoa has received much attention because it contains a high content of proteins, essential amino acids, essential fatty acids, minerals, vitamins, dietary fibers, and bioactive compounds. Nevertheless, this content and the bioavailability of specific compounds of interest are related to the genotype, the agri‐environmental conditions, and management practices where quinoa is grown and postharvest management. This article aimed to analyze the research trends for three knowledge areas: quinoa plant breeding for nutraceutical properties, plant–soil relations focused on abiotic stresses, and postharvest and value‐added transformation activities. To this end, a specific methodological design based on bibliometrics and scientometrics methods was used. Through these analyses based on publications' keywords, titles, abstracts, and conclusions sections, for each knowledge area, the key research trends (scope and main topics), the classification of trends based on their development and relevance degree, and the core of knowledge were established. The trends comprise the current state of research. Finally, analyzing the conclusions, recommendations, and future research sections of key publications, a strong correlation among plant breeding research to obtain varieties with tolerance to biotic and abiotic stresses, nutritional and functional compounds of interest for food safety, and the development of products with higher added value established interest in further research on the potential bioactivity of quinoa and the verification of health benefits to humans.

“…and C. ficifolium Sm. carry the BB genome, and these two species have recently been shown to be cross-fertile (Hodkova and Mandak, 2018); however, identification of the A-genome ancestor may prove more difficult, with C. watsonii A. Nels. emerging as the leading candidate.…”

2019. New seed collections of North American pitseed goosefoot (Chenopodium berlandieri) and efforts to identify its diploid ancestors through whole-genome sequencing. Cien. Inv. Agr. 46(2): 187-196. Pitseed goosefoot (Chenopodium berlandieri) is an ecologically diverse wild/weedy North American species within the primary gene pool for improving South American quinoa (Chenopodium quinoa). Both taxa are 36-chromosome allotetraploids with subgenomes AA and BB. The A genome is found in a large number of diploids in the Americas, along with one Northeast Asian taxon, and was recently shown to be the maternal ancestor, while the paternal B genome is closely related to several extant Eurasian diploids. Two of our primary objectives were 1) to determine the extent of genetic diversity in the allotetraploid C. berlandieri-quinoahircinum complex and 2) to characterize the evolutionary path from polyploidization to domestication in these taxa. In an effort to survey genetic diversity, in 2018, we made seed collections of southern Texas, southern Great Plains, and New England coastal ecotypes of C. berlandieri as well as sympatric diploids. With respect to the second goal, we performed wholegenome sequencing of two Sonoran Desert Chenopodium A-genome diploids in subsection Cellulata and Andean cultivated C. pallidicaule in subsection Leiosperma. When paired reads were aligned to the whole-genome reference of C. quinoa strain 'QQ74', the match percentages were 99.31, 99.23, and 98.53 for C. watsonii, C. sonorense, and C. pallidicaule, respectively. These data strongly support C. watsonii as being the most closely related of these three species to the A-genome ancestor of quinoa. Ongoing sequencing efforts with a larger panel of diploids are aimed at identifying the maternal ancestor of C. quinoa and C. berlandieri, if extant.
