Hormonal and plant factors regulating the development of the inhibited cotyledonary buds of Lycopersicon esculentum Mill. cv. ;Fireball' seedlings were studied. Excision of the immature plumular leaves of 5- to 20- millimeter length significantly stimulated bud development after 2 to 4 days, but excision of leaves exceeding 20-millimeter length was without effect. Apical application of 20 micro...

A stable Agrobacterium-mediated transformation system was established using bialaphos as the selective agent in soybeans [Glycine max (L.) Merr.]. The cotyledonary node explants of the soybean cultivar ‘NY-1001’ were inoculated with the Agrobacterium tumefaciens strain EHA105, harboring the vector pCAMBIA3301 containing the gus gene as the reporter gene and the bar gene conferring bialaphos res...

In pregnant sheep, maternal:fetal exchange occurs across placentomes composed of placental cotyledonary and uterine caruncular tissues. Recently, we reported that fetal weights of obese (OB) ewes [fed a diet of 150% of National Research Council (NRC) recommendations] were approximately 30% greater than those of control (C) ewes (fed a diet 100% of NRC recommendations) at midgestation (MG), but ...

A method for regenerating pigeonpea {Cajanus cajan (L.) Millsp.} plants has been developed using cotyledonary nods and embroyonic axes of mature seeds as explants. A large number of shoot buds were induced directly from explants of genotypes Pusa-9 and Bahar when cultured on different basal media fortified with a range of BAP concentrations (0–2 mg/l) and 0–0.5 mg/l gibberellic acid (GA ) eithe...

Obesity of women at conception is increasing, a condition associated with offspring obesity. We hypothesized that maternal obesity increases placental fatty acid transporter (FATP) expression, enhancing delivery of fatty acids to their fetuses. Sheep are a commonly utilized biomedical model for pregnancy studies. Nonpregnant ewes were randomly assigned to a control group [100% of National Resea...

The sensitive plant Mimosa pudica has long attracted the interest of researchers due to its spectacular leaf movements in response to touch or other external stimuli. Although various aspects of this seismonastic movement have been elucidated by histological, physiological, biochemical, and behavioral approaches, the lack of reverse genetic tools has hampered the investigation of molecular mech...
