The variability of essential oil characteristics in different phenological stages of Clinopodium pulegium from its natural habitat (Svrljiški Timok gorge, Serbia) and from cultivated plants (Niš, Serbia) was determined. The essential oils were obtained from aerial parts of the plants by hydrodistillation and analyzed by GC-MS. These are the first data on the essential oil characteristics of pla...

Five recombinant inbred lines (RILs) of Arabidopsis (Arabidopsis thaliana), previously selected from the Bay-0 x Shahdara RIL population on the basis of differential leaf senescence phenotypes (from early senescing to late senescing) when cultivated under nitrogen (N)-limiting conditions, were analyzed to monitor metabolic markers related to N assimilation and N remobilization pathways. In each...

Cu is an essential element for plant growth, but the molecular mechanisms of its distribution and redistribution within the plants are unknown. Here, we report that Yellow stripe-like16 (YSL16) is involved in Cu distribution and redistribution in rice (Oryza sativa). Rice YSL16 was expressed in the roots, leaves, and unelongated nodes at the vegetative growth stage and highly expressed in the u...

We characterized the absorption and short-term translocation of cadmium (Cd) in rice (Oryza sativa 'Nipponbare') quantitatively using serial images observed with a positron-emitting tracer imaging system. We fed a positron-emitting 107Cd (half-life of 6.5 h) tracer to the hydroponic culture solution and noninvasively obtained serial images of Cd distribution in intact rice plants at the vegetat...

The fungus Phymatotrichum omnivorum (Shear) Duggar, the cause of cotton root rot, has three known stages in its life history, namely, (i) a vegetative or Ozonium stage (^),^ (2) a conidial or Phymatotrichum stage {!), and {S) a sclerotial stage (4). Several investigators have shown that the sclerotia, or hold-over bodies, are usually present in the soil wherever the disease is found, and play a...

The coordination of chromosome segregation with cell growth is fundamental to the proliferation of any organism. In most unicellular bacteria, chromosome segregation is strictly coordinated with cell division and involves ParA that moves the ParB nucleoprotein complexes bi- or unidirectionally toward the cell pole(s). However, the chromosome organization in multiploid, apically extending and br...

Flowering occurs in angiosperms during a major developmental transition from vegetative growth to the reproductive phase. Squamosa promoter binding protein (SBP)-box genes have been found to play critical roles in regulating flower and fruit development, but their roles in grapevine have remained unclear. To better understand the functions of the grape SBP-box genes in both vegetative and repro...
