We have previously visualized three Ca2+ transients, generated by release from intracellular stores, which are associated with cytokinesis during the early cell division cycles of zebrafish embryos: the furrow positioning, propagation and deepening transients. Here we demonstrate the requirement of the latter for furrow deepening, and identify the Ca2+ release channels responsible for generatin...
Deep tillage of compacted soils can improve potato (Solanum tuberosum L.) tuber yield and quality if no other production factors are limiting. We hypothesized that within-row subsoiling and N placement would affect tuber yields and availability of plant nutrients. Potato (cv. Russet Burbank) was grown after winter wheat (Triticum aestivum L.) in 1989 and after dry bean (Phaseolus vulgaris L.) i...
Cortical compartments partition proteins and membrane at the cell surface to define regions of specialized function. Here we ask how cortical compartments arise along the plasma membrane furrows that cellularize the early Drosophila embryo, and investigate the influence that this compartmentalization has on furrow ingression. We find that the zygotic gene product Nullo aids the establishment of...
Aims: Optimization of machine parameters (type flail blade and number strip-till blades per flange) operational (rotor shaft speed forward speed) for the development stubble manager cum crop planter conservation agriculture.
 Study Design: Split plot (3 factors); Type blade/number flange as main rotor sub plots.
 Place Duration Study: Dr. NTR College Agricultural Engineering, Bapatla,...
The physical interaction of the plasma membrane with the associated cortical cytoskeleton is important in many morphogenetic processes during development. At the end of the syncytial blastoderm of Drosophila the plasma membrane begins to fold in and forms the furrow canals in a regular hexagonal pattern. Every furrow canal leads the invagination of membrane between adjacent nuclei. Concomitantl...
To investigate yield and water use efficiency (WUE) of potato with tape and furrow irrigations, an experiment was performed at Hamadan Agricultural and Natural Resources Research Center (Ekbatan station) in 2004. The experiment was arranged in a split-plot experimental design based on completely randomized block with 3 replications of irrigation water amount as the main factor (75%, 100%, 125% ...
Plasma membrane furrow formation is crucial in cell division and cytokinesis. Furrow formation in early syncytialDrosophila embryos is exceptionally rapid, with furrows forming in as little as 3.75 min. Here, we use 4D imaging to identify furrow formation, stabilization, and regression periods, and identify a rapid, membrane-dependent pathway that is essential for plasma membrane furrow formati...
The soil-borne fungus Rhizoctonia solani causes damping-off on sugar beet seedlings. Growers rely fungicides to protect in fields affected by R. solani. Quinone outside inhibitor (QoI) fungicides, such as azoxystrobin, have been applied in-furrow and foliar sprays manage solani, but repeated use of QoI pose risks fungicide resistance. Penthiopyrad is a novel with the succinate dehydrogenase (SD...
In this research, the hydraulic behavior of furrow irrigation was investigated under cut-back, Walker-Skogerboe and conventional methods at the three experimental farms of Lavark, Shervedan, and Isfahan University of Technology for three irrigation events. In each farm, data were collected for each of the above methods with at least three replications including furrow shape, furrow length, furr...
