Isolation of RNA from plants rich in secondary metabolites using commercial kits often results in contaminated preparations which are not suitable for downstream applications. Although many specific protocols appropriate for plants with a high content of phenolics, anthocyanins and polysaccharides have been developed, these are often expensive, time consuming and not applicable to different typ...

is added to grapefruit pulp the pulp acts as a bland filler and makes an apple pie. If peach is added it makes a peach pie. Citric acid, sugar and peel oil give excellent orange, grapefruit and tangerine jams. A little' peel oil, sunset yellow, No. 6 and sugar makes a good ice cream mix. Add more sugar and you have a good sundae topping. Cake fillings were made from the jams but they gave troub...

Social odours, conspecific chemical signals, have been demonstrated in every class of vertebrate except birds. The apparent absence is surprising, as every bird examined has a functional olfactory system and many produce odours. The crested auklet (Aethia cristatella), a monogamous seabird, exhibits a distinctive tangerine-like scent closely associated with courtship. Using T-maze experiments, ...

Carotenoids are vital components of photosynthetic cells, where they play important accessory roles in light harvesting and energy transfer to the chlorophylls, maintain structural integrity of the photosynthetic apparatus, and provide photoprotection against the damaging effects of reactive oxygen species that are by-products of photosynthesis. Violaxanthin and neoxanthin also serve as precurs...

Relevance . When creating tomato varieties and hybrids, much attention is paid not only to the commercial component (yield, appearance uniform ripening), but also taste qualities of products. Salad with yellow, tangerine, pink fruits are increasingly in demand. As a rule, these do store for long time, so it necessary increase their storability transportability. Fruits this group tomatoes have h...

The photosynthetic responses to moderately high temperatures (38 degrees C, imposed at 21% or 2% O(2) in air and 1500 mumol m(-2) s(-1)) were compared in wheat (Triticum aestivum L.) cultivars grown in northern regions of Ukraine and expected to be relatively sensitive to high temperatures ('North' cultivars) and in cultivars grown in southern regions and expected to be relatively heat-tolerant...

Leaf extracts of 27 `Yuzu' and related acid citrus cultivars were analyzed using polyacrylamide gel electrophoresis for isozyme variation of glutamate oxaloacetate transaminase (GOT) and shikimate dehydrogenase (SDH). SDH yielded 12 different isozyme phenotypes and six cultivars were discriminated by this enzyme alone. GOT produced 10 different isozyme phenotypes and four cultivars were separat...
