Key planting factors that influence corn stand establishment includes uniform depth and spacing of seed, correct seed population and optimizing the soil environment for rapid germination and uniform emergence. Other variables affecting stand establishment are seedbed quality (including soil moisture and temperature), seed quality and planter speed. Differences among fields for stand establishme...

Stand establishment problems occur frequently in Arkansas rice fields and are commonly associated with cool soil temperatures (early planting) and saturated soils. There are several factors that affect rice stand establishment including diseases and insects. It is important to understand what pathogens or pests are the cause of stand problems in rice for managing stand establishment problems. I...

Mitotic spindle orientation is a conserved, dynamic, and highly complex process that plays a key role in dictating the cleavage plane, fate, and positioning of cells within a tissue, therefore laying the blueprint for tissue structure and function. While the spindle-positioning pathway has been extensively studied in lower-model organisms, research over the past several years has highlighted it...

By using fluorescent labelling techniques, the distribution and dynamics of proteins can be measured within living cells, allowing to study in vivo the response of cells to a triggering event, such as DNA damage. In order to evaluate the reaction rate constants and to identify the proteins and reactions that are essential for the investigated process, mechanistic models are used, which often co...

Snail shells can be left-handed or right-handed, sometimes within one species. For over a century, it has commonly been assumed that mirror-image shell coiling in snails is correlated with a mirror- image reversal of early spindle orientation and cleavage. The results of an exciting and elegant new study refute this model, showing that right doesn't have to be the mirror image of left.
