The vascular tissue of higher plants is organized into a continuous and unified system that undergoes a transition between two highly differentiated structures, the root and the shoot. This transition was studied in tomato by investigating the genetic basis of morphological variation between Lycopersicon esculentum and L. hirsutum LA407. Our analysis concentrated on morphology in stem cross sec...

Glutamine synthetase was localized in leaves and cotyledons of young tomato (Lycopersicon esculentum Mill.) plants using immunogold techniques coupled to transmission electron microscopy. The enzyme occurs only in chloroplasts and is most probably a stroma constituent.

Net ammonium and nitrate influx were independent of transpiration rate for intact seedlings of both a wild species of radish (Raphanus raphanistrum) and a wilty tomato mutant (Lycopersicon esculentum Mill. cv RR flacca).

This study of functional diversity considers symbiotic associations between two plant species, Medicago truncatula and Lycopersicon esculentum, and seven species of arbuscular mycorrhizal fungi (AMF). The objective was to integrate physiological analyses with molecular techniques to test whether functional diversity between AMF species is not only apparent at the level of mycorrhiza formation, ...

Pteridium is a cosmopolitan genus that acts as an invasive species in many parts of the world. Most research on this genus has occurred in Europe, and there is a lack of data on it from South America, in spite of causing considerable conservation problems. We compared the biomass allocation of P. esculentum subsp. arachnoideum in two ecosystems in Brazil - Atlantic forest and Brazilian savanna....

The eVect of dietary supplements on the longevity of male and female Gonatocerus ashmeadi, G. triguttatus and G. fasciatus (Hymenoptera: Mymaridae), was determined in the laboratory. Treatments included: water only, 3:1 honey–water solution, Xoral and extraXoral nectars from Wve diVerent plants (excised stems from Fagopyrum esculentum, Lobularia maritima, Phacelia tanacetifolia, Anethum graveol...

Bu çalışmanın amacı farklı konsantrasyonlarda (0-12 g/100g) karabuğday unları (Fagopyrum esculentum) ile zenginleştirilmiş dut pestillerin bazı fiziko-kimyasal, renk, biyoaktif ve duyusal özelliklerini araştırmaktır. Dut protein içerikleri 5.87-6.89 g/100g aralığında değişmiş unu ilavesiyle anlamlı bir artma bulunmuştur (P

lead (pb), has, for decades, being known for its adverse effects on various body organs and systems. in the present study, the damage of pb on the liver tissue apoptosis was investigated, and lycopersicon esculentum as an antioxidants source was administered orally to prevent the adverse effects of pb. eighteen wistar rats, randomized into three groups (n=6), were used for this study. animals i...

Erysiphe is the largest genus of powdery mildews (PMs), a group obligate plant pathogenic fungi. Exploration biodiversity generally relies on regional surveys and our aim to investigate PMs in Taiwan. Collections fungi five species around agricultural environments were subjected morphological molecular characterization, using both internal transcribed spacer (ITS) β-tubulin gene (TUB2) regions ...
