The peanut plant (Arachis hypogaea L.) produces flowers aerially, but buries the recently fertilized ovules in the soil in order for the fruit and seeds to mature underground. The organ that carries the seeds into the soil is called the gynophore. The growth of the peanut gynophore is regulated primarily by indole-3-acetic acid (IAA). A monoclonal antibody raised against IAA was used to success...

We have conducted a comprehensive metabolic profiling on tomato (Lycopersicon esculentum) leaf and developing fruit tissue using a recently established gas chromatography-mass spectrometry profiling protocol alongside conventional spectrophotometric and liquid chromatographic methodologies. Applying a combination of these techniques, we were able to identify in excess of 70 small-M(r) metabolit...

Real-time quantitative PCR was used to study lipoxygenase (LOX) gene expression patterns in kiwifruit (Actinidia deliciosa [A. Chev.] C.F. Liang et A.R. Ferguson var. deliciosa cv. Hayward) during fruit ripening, and in response to ethylene and low temperature during post-harvest storage. Six LOX genes were identified and cloned from a kiwifruit EST database. All were expressed in vegetative ti...

Aging cylinders excised from ;Golden Delicious' apple (Pyrus malus L.) pulp, like the intact fruit, exhibit some characteristic phenomena such as rise in respiration (climacteric), ethylene synthesis, enzymic changes, and increase in ribosomes and mRNA. Aging of cylinders of pulp tissues may offer a useful physiological tool for the study of maturation and senescence.

A genomic clone encoding ascorbate oxidase was isolated from pumpkin (Cucurbita sp.). This gene is consisted of four exons and three introns. Analyses of the promoter fusion to beta-glucuronidase reporter gene by transient expression assay in pumpkin fruit tissues suggested the existence of a cis-acting region responsible for auxin regulation.

The article presents an analysis of the features weather conditions in 2020 Central Black Earth Region. It determines main deviations from average long-term values air temperature and humidity, as well distribution precipitation. shows influence climate change recent decades, which is destabilization water-temperature regime, on passage phenophases development fruit plants, including dormant pe...

1. The polysaccharide compositions of the cell walls of sycamore cambium and sycamore callus tissue have been analysed and found to be directly comparable. 2. Electrophoretic analyses of the whole pectins prepared from actively growing callus and cambial tissue have shown that these preparations contain, in addition to the neutral and weakly acidic components present in apple fruit, a strongly ...

Transient expression of foreign genes in plant tissues is a valuable tool for plant biotechnology. To shorten the time for gene functional analysis in fruits, we developed a transient methodology that could be applied to tomato (Solanum lycopersicum cv Micro Tom) fruits. It was found that injection of Agrobacterium cultures through the fruit stylar apex resulted in complete fruit infiltration. ...

Strawberry (Fragaria x ananassa) fruit contains several anthocyanins that give the ripe fruits their attractive red color. The enzyme that catalyzes the formation of the first stable intermediate in the anthocyanin pathway is anthocyanidin-3-O-glucosyltransferase. A putative glycosyltransferase sequence (FaGT1) was cloned from a strawberry fruit cDNA library and the recombinant FaGT1 transferre...

Methods are recommended and described for determining Pyrethrin I, Cinerin I, Pyrethrin II, Cinerin II and Jasmolin II with or without combination with synergists such as piperonyl butoxide, in milk, fish and meat, Lat and meat by-products of cattle, goats, hogs, horses, sheep, poultry tissues and eggs using g.l.c. arid t.l,c, It is probably adaptable to cereals, fruit and oilseeds.
