Summary: This study explored the medicinal value of carrot leaves and isolated six flavone glycosides from them. A method using NMR and HPLC/UV was developed for their quantitation. Enzymatic deglycosylation of the flavone glycosides was assessed, and the enzyme-treated carrot leaves showed higher inhibitory effects on TNF-a and IL-2 expression. These findings highlight the importance of carrot leaves and provide baseline data for commercial development.

Summary: The experiment revealed that DcAOX2a plays a dual role in carrot tap root secondary growth and cold stress response, while DcAOX1 shows less correlation. Cold stress generally up-regulated DcAOX2a without consistent effects on DcAOX1, indicating a potential key role of DcAOX2a in the response to stress. The identification of cis-acting regulatory elements at the promoters of both genes showed putative sequences involved in cold stress responsiveness and growth, with DcAOX2a promoter presenting more CAREs related to hormonal pathways than DcAOX1.

Summary: A genotyping by sequencing (GBS) approach was used to analyze the genetic diversity in V. pubescens and V. chilensis. The cultivated V. pubescens exhibited low genetic diversity and differentiation, while V. chilensis showed high genetic diversity. Critical SNPs/INDELs associated with stress responses and development were identified. These results will be beneficial for future breeding and conservation programs.

Summary: Plant class III peroxidases are involved in essential plant processes, and this study identified and classified 75 carrot peroxidases into seven subgroups based on phylogenetic analysis. The gene structure and conserved motif analyses revealed characteristic features of carrot peroxidases. Tandem duplication was found to be the main contributor to the expansion of this gene family, and RNA sequencing identified candidate genes related to lignification and pigmentation mechanisms.

Summary: The biodiversity of carrot is important for human diet as it provides useful and necessary components. Eight carrot genotypes with different root colors were distinguished using amplified fragment length polymorphism (AFLP) markers. Three sets of primer pairs produced 92 loci, including 60 polymorphic ones. The genetic distances between the genotypes were calculated using Nei's coefficient. The AFLP method can be used for genetic diversity assessment in carrot breeding accessions with slight modifications including gel staining.

Summary: Understanding the population structure and genetic diversity of wild populations is crucial for stock management and conservation. This study investigated the population structure and genetic diversity of common carp in the Southern Caspian basin using genotyping-by-sequencing. The results showed low differentiation between populations and high within population variation. Frequent migration events were observed, but each population still had distinct genetic profiles. However, high inbreeding and low heterozygosity were detected, indicating the need for additional conservation efforts.

Summary: The present study characterized a diverse collection of purple and non-purple carrot accessions for their concentration of anthocyanins, phenolics, carotenoids, and antioxidant capacity. Significant variation was found among the accessions, with acylated anthocyanins being the most dominant pigment. Purple carrots exhibited higher levels of anthocyanins, phenolics, and antioxidant capacity compared to non-purple carrots. Antioxidant capacity was positively correlated with anthocyanin content and total phenolic content, but not with carotenoids. Certain accessions were identified as potential sources for food dyes or increased nutraceutical value.

Summary: Early assessment of crop development is crucial in precision agriculture. This study aimed to predict the yield of four maize hybrids using vegetation indices. Ten vegetation indices were evaluated at different stages after sowing, and a multivariate analysis was conducted. The results showed significant correlations between vegetation indices and plant cover at specific stages, particularly at 51 days after sowing. The inclusion of certain vegetation indices improved the prediction model's precision. The use of unmanned aerial vehicles in crop monitoring can optimize resource utilization and aid in timely decision-making in agriculture.

Summary: This study developed and evaluated genomic prediction strategies to identify valuable breeding material in crop germplasm collections. The models had moderate ability to predict trait values of evaluated germplasm accessions, suggesting that genomic selection may allow for the identification of valuable germplasm accessions without extensive field evaluation.

Summary: The spatial heterogeneity of soil properties affects crop growth, making it challenging to adopt site-specific crop management practices. Traditional laboratory-based analyses are costly and data extrapolation for mapping soil properties using high-resolution imagery is time-consuming. This study explored the feasibility of using Google Earth Engine (GEE) to develop a digital soil mapping approach using high-resolution reflectance imagery derived from a thermal infrared and multispectral camera. The results indicate that the predictions based on spectral indices, in combination with machine learning algorithms, are superior to those based on individual spectral bands, and the inclusion of a digital surface model improves the prediction accuracy.

Summary: This study used high-throughput Illumina MiSeq sequencing to explore the composition, diversity, and functions of fungal and bacterial communities in Quinoa affected by monocropping in Peru. The results showed that monocropping and soil types significantly changed the structure of bacterial and fungal communities. There was an increase in Actinobacteria and a decrease in Proteobacteria in monocropped soils, as well as a decrease in the presence of Ascomycota and an increase in Basidiomycota. This research provides a starting point to investigate the importance and effects of microorganisms in degraded soils and their impact on the growth and quality of quinoa crops.
