Turnip (Brassica rapa var. rapa L.), beetroot (Beta vulgaris L.) and carrot (Daucus carota L.) are common vegetables in South Africa. The allelopathic potential of aqueous leaf and root extracts of Aloe ferox Mill.a highly valued medicinal plantwas evaluated against seed germination and seedling growth of the three vegetables in Petri dish experiments. The extracts were tested at concentrations...

Stress-adaptive cell plasticity in target tissues and cells for plant biomass growth is important for yield stability. In vitro systems with reproducible cell plasticity can help to identify relevant metabolic and molecular events during early cell reprogramming. In carrot, regulation of the central root meristem is a critical target for yield-determining secondary growth. Calorespirometry, a t...

Chronic lymphocytic leukemia (CLL) is one of the chronic lymphoproliferative disorders (lymphoid neoplasms). It is characterized by a progressive accumulation of functionally incompetent lymphocytes. Patients with leukemia often seek unconventional treatments not prescribed by hematologist in order to improve their cancer treatment outcome or to manage symptoms. In the present report, a 76-year...

Carrot cultivars grown in New York were evaluated for susceptibility to the fungal leaf blight pathogens Alternaria dauci (1999) and Cercospora carotae (2000–03) in an experimental field under continuous carrot cultivation since 1996. Replicated plots were established in a randomized complete block design. Plants were rated for disease incidence and severity at regular intervals. Cultivar susce...

Domesticated carrots, Daucus carota subsp. sativus, are the richest source of β-carotene in the US diet, which, when consumed, is converted into vitamin A, an essential component of eye health and immunity. The Y2 locus plays a significant role in beta-carotene accumulation in carrot roots, but a candidate gene has not been identified. To advance our understanding of this locus, the genetic bas...

Root-knot nematodes limit carrot production around the world by inducing taproot forking and galling deformities that render carrots unmarketable. In warmer climates, Meloidogyne javanica and Meloidogyne incognita are most prevalent. In F2 and F3 progeny from the cross between an Asian carrot resistant to M. javanica, PI 652188, and a susceptible carrot, resistance response was incompletely dom...

BACKGROUND Onychodystrophy refers to the various abnormalities in nail morphology due to changes in the attachment of the nail plate, changes in nail surface or color. The treatment principle of onychodystrophy largely relies on the discovery and verification of the cause. However, preventive treatment methods offer little help to the patient due to poor compliance, and the effect of corticoste...

bryogenesis is usefu1 for isolating genes expressed during embryogenesis, as embryegenic competence and the expressien of certain embryo-specific genes increases with increased stress. Fluorescent differential display (FDD) was perfonmed to isolate stress-induced genes in carrot somatic embryos, and five genes were isolated as embryonic tissue-specific genes. One ofthese genes was expressed unt...

The prevalence of non-autonomous class II transposable elements (TEs) in plant genomes may serve as a tool for relatively rapid and low-cost development of gene-associated molecular markers. Miniature inverted-repeat transposable element (MITE) copies inserted within introns can be exploited as potential intron length polymorphism (ILP) markers. ILPs can be detected by PCR with primers anchored...
