The highest concentrations of herbicides measured in flowing surface waters are often only present for short periods of time. These herbicide pulses can reach concentrations that would affect aquatic plants if present over a long time. The aim of this
Mitosis in plants can be blocked by colchicine which has the capacity to bind microtubule subunits. In maize (Zea mays L.) breeding, it is frequently being used for doubling chromosome numbers of haploids for producing homozygous doubled haploids. However, colchicine
The sku6-1 mutant of Arabidopsis thaliana exhibits altered patterns of root and organ growth. sku6 roots, etiolated hypocotyls, and leaf petioles exhibit right-handed axial twisting, and root growth on inclined agar media is strongly right skewed. The touch-dependent sku6 root
Lipid bodies present in lipotubuloids of Ornithogalum umbellatum ovary epidermis take the form of a lens between leaflets of ER (endoplasmic reticulum) membrane filled with a highly osmiophilic substance. The two enzymes, DGAT1 [DAG (diacylglycerol) acyltransferase 1] and DGAT2 (DAG
Fibrillarin is known to play an important role in precursor ribosomal RNA processing and ribosome assembly. The present study describes a fibrillarin homolog gene isolated from tobacco BY-2 cells and its expression during the cell cycle. The cDNA for a
