Transcriptome Analysis Reveals the Molecular Mechanisms of Carrot Adaptation to Alternaria Leaf Blight.

Carrot ( L.) is an important vegetable crop that is rich in carotenoids and is widely cultivated throughout the world. Alternaria leaf blight (ALB), caused by infection with (), is the most serious fungal disease in carrot production.

Complete genome sequence of the carrot black rot pathogen Alternaria radicina isolate CBR2.

Black rot, caused by Alternaria radicina, seriously endangers carrots throughout the growing season, affecting both leaves and fleshy roots. In this study, we sequenced and assembled the genome of the A. radicina isolate CBR2.

First Report of Black Rot of Carrot Caused by Alternaria carotiincultae in China.

China is the world's largest producer and exporter of carrot (Daucus carota L. var. sativa), a well-known and nutritious root vegetable.

Lycopene ε-cyclase mediated transition of α-carotene and β-carotene metabolic flow in carrot fleshy root.

The accumulation of carotenoids, such as xanthophylls, lycopene, and carotenes, is responsible for the color of carrot (Daucus carota subsp. sativus) fleshy roots. The potential role of DcLCYE, encoding a lycopene ε-cyclase associated with carrot root color, was investigated using cultivars with orange and red roots.

Draft Genome Sequence of Carrot Alternaria Leaf Blight Pathogen .

The fungal genus , which causes a variety of crop diseases, is widely distributed in the world. Alternaria leaf blight, caused by , is one of the most common and destructive diseases in carrot. The infection of leads to dramatic decay on both foliage and taproot in severe cases, which results in significant yield losses.

Genome-wide identification and characterization profile of phosphatidy ethanolamine-binding protein family genes in carrot.

Members of the family of Phosphatidy Ethanolamine-Binding Protein (PEBP) have been shown to be key regulators of the transition of plants from vegetative to reproductive phases. Here, a total of 12 PEBP proteins were identified in the carrot ( L.) genome and classified into FT-like (4), TFL1-like (6), and MFT-like 2) subfamilies, that had different lengths (110-267 aa) and were distributed unevenly across seven chromosomes.

Differential hydroxylation efficiency of the two non-heme carotene hydroxylases: DcBCH1, rather than DcBCH2, plays a major role in carrot taproot.

Carotene hydroxylase plays an important role in catalyzing the hydroxylation of carotene to xanthopylls, including two types: non-heme carotene hydroxylase (BCH type) and heme-containing cytochrome P450 hydroxylase (P450 type). Two BCH-encoding genes were annotated in the carrot genome. However, the role of BCHs and whether there are functional interactions between the duplicated BCHs in carrot remains unclear.

Advances in engineering the production of the natural red pigment lycopene: A systematic review from a biotechnology perspective.

Background: Lycopene is a natural red compound with potent antioxidant activity that can be utilized both as pigment and as a raw material in functional food, and so possesses good commercial prospects. The biosynthetic pathway has already been documented, which provides the foundation for lycopene production using biotechnology.

Aim Of Review: Although lycopene production has begun to take shape, there is still an urgent need to alleviate the yield of lycopene.

Detection of Chromosomal Segments Introgressed from Wild Species of Carrot into Cultivars: Quantitative Trait Loci Mapping for Morphological Features in Backcross Inbred Lines.

Cultivated carrot is thought to have been domesticated from a wild species, and various phenotypes developed through human domestication and selection over the past several centuries. Little is known about the genomic contribution of wild species to the phenotypes of present-day cultivars, although several studies have focused on identifying genetic loci that contribute to the morphology of storage roots. A backcross inbred line (BIL) population derived from a cross between the wild species ssp.

The Response of COL and FT Homologues to Photoperiodic Regulation in Carrot (Daucus carota L.).

Carrot (Daucus carota L.) is a biennial plant requiring vernalization to induce flowering, but long days can promote its premature bolting and flowering. The basic genetic network controlling the flowering time has been constructed for carrot, but there is limited information on the molecular mechanisms underlying the photoperiodic flowering response.

Differentially Expressed Genes between Carrot Petaloid Cytoplasmic Male Sterile and Maintainer during Floral Development.

Petaloid cytoplasmic male sterility (CMS) is a maternally inherited loss of male fertility due to the complete conversion of stamens into petal-like organs, and CMS lines have been widely utilized in carrot breeding. Petaloid CMS is an ideal model not only for studying the mitochondrial-nuclear interaction but also for discovering genes that are essential for floral organ development. To investigate the comprehensive mechanism of CMS and homeotic organ alternation during carrot flower development, we conducted transcriptome analysis between the petaloid CMS line (P2S) and its maintainer line (P2M) at four flower developmental stages (T1-T4).

The dual role of phytoene synthase genes in carotenogenesis in carrot roots and leaves.

Carrot ( L.) is an important food crop and is useful for studying carotenogenesis due to the quantity and diversity of carotenoids in its roots. Phytoene synthase catalyzes the first committed step in the carotenoid biosynthesis pathway, and its overexpression is the main driving force in the orange phenotype.

[QTL mapping for contents of main carotenes and lycopene in carrot (Daucus carota L.)].

An F2 population derived from two carrot inbred lines, P50006 and HCM A.C. with high carotene accumulation, was developed and used to map and analyze quantitative trait locus (QTL) associated with the accumulation of alpha and beta-carotene, total carotene and lycopene.

Cucumis monosomic alien addition lines: morphological, cytological, and genotypic analyses.

Cucumis hystrix Chakr. (HH, 2n=24), a wild relative of the cultivated cucumber, possesses several potentially valuable disease-resistance and abiotic stress-tolerance traits for cucumber ( C. sativus L.
