ISSUE ADDRESSED Populations in many developed countries continue to fail to meet vegetable consumption recommendations despite ongoing health promotion activities supported by public health policies. Novel ways to encourage vegetable consumption may help address this concern. The aim of the present study was to describe female consumers' perceptions about leafy green vegetables and identify con...

Major chloroplast pigments in five leafy vegetables (chicory-Cichorium intybus, cv. 'Anivip' and cv. 'Monivip', dandelion-Taraxacum officinale, garden rocket-Eruca sativa and wild rocket-Diplotaxis tenuifolia), commonly consumed in Mediterranean countries, have been separated by high-performance liquid chromatography (HPLC) on a reversed-phase column. Three classes of pigments were identified a...

The loss caused by the so-called minor diseases is not usually considered of sufficient importance to warrant the adoption of control measures such as those used in combating major diseases; nevertheless it has frequently been asserted that if the total loss due to the activities of all minor diseases could be estimated it would probably amount to more than is imagined. Further, a disease which...

Previous evidence indicates that changes in well-defined phases of dormancy in underground adventitious buds of leafy spurge in late summer and autumn are regulated by complex sensing and signaling pathways involving aboveground sugar signals. However, little information exists concerning seasonal photosynthesis and carbohydrate partitioning of leafy spurge, although such information would help...

Two demonstration sites in southeast Idaho were used to extend the scope of remote sensing of leafy spurge research toward investigating coarser scale detection limits. Hyperspectral images were obtained to produce baseline leafy spurge maps, from which spatially and/or spectrally degraded images were subsequently derived for comparative purposes with Landsat 5 Thematic Mapper (TM). The baselin...

Climatic oscillations and geological events play major roles in shaping species diversity and the distribution of plants. The mechanisms underlying the high level of plant species diversity in eastern Asia are hotly debated. In this study, five cpDNA regions, two mtDNA fragments and one nuclear gene (LEAFY) were employed to investigate species diversification and the historical biogeography of ...

The purpose of this study was to assess heavy metal contamination and health risks for residents in the vicinity of a tailing pond in Guangdong, southern China. Water, soil, rice, and vegetable samples were collected from the area in the vicinity of the tailing pond. Results showed that surface water was just polluted by Ni and As, while groundwater was not contaminated by heavy metals. The con...

In previous studies trace levels of perchlorate were found in lettuce (Lactuca sativa L.) irrigated with Colorado River water, which is contaminated with low levels of perchlorate from aerospace and defense related industries. In this paper, we report the results of a survey conducted across North America to evaluate the occurrence of perchlorate in leafy vegetables produced outside the lower C...

Auxin resistant 1/like aux1 (AUX/LAX), pin-formed (PIN) and ATP binding cassette subfamily B (ABCB/MDR/PGP) are three families of auxin transport genes. The development-related functions of the influx and efflux carriers have been well studied and characterized in model plants. However, there is scant information regarding the functions of auxin genes in Chinese cabbage and the responses of exo...
