A method for Agrobacterium-mediated transformation of hybrid
poplar (Populus alba x P. grandidentata) suspension cultures and
regeneration of transformed plants is described. The best protocol
was one in which suspension cultures were inoculated with
Agrobacterium tumefaciens to a density of 10⁷ cfu's/ml, cocultivated
for 48 hours, plated to cellulose acetate...
Truancy and dropout are two issues plaguing school districts across the nation. The short- and long-term consequences of both problems are complex and far reaching, affecting students, families, and communities.

The cultivated sunflower (Helianthus annuus L., x=17) is one of the most important annual oilseed crops in the world. There are very few publicly shared sequence-based DNA markers and genetic maps in sunflower, even though molecular DNA markers and genetic maps have become widely used in all areas of genetic...
Boron sprays produced fruit set increases in 'Barcelona'
hazelnut orchards in 1984 and in 1985. The absolute fruit set was
correlated with leaf B content but not with nut B. With relative
fruit set (RFS), B content of nuts in May (r = 0.63**) was more
strongly related to set...
Victoria blight, caused by fungus Cochliobolus victoriae, is a disease originally described on oats and recapitulated on Arabidopsis. Victoria blight is used as a model plant disease that conforms to an inverse gene-for-gene interaction. C. victoriae virulence is dependent upon its production of victorin, a host-specific toxin that induces programmed...
Emerging adults often encounter obstacles and adversity in pursuit of occupational identity. College counselors are responsible for delivering mental health, wellness, and career services to distressed students facing unprecedented challenges to enter the workplace.
