Corn lily or California false hellebore (Veratrum californicum Durand), a perennial species native to the western United States, produces several alkaloid compounds. A derivative of these alkaloid compounds, primarily veratramine and cyclopamine, shows promise as a therapeutic agent for treatment of a variety of tumor types. Here we report the first study of corn lily cultivated in greenhouse. Growth response of corn lily was examined under two light levels (ambient and supplemental), two fertilization types (20 N-4.4 P-16.6 K Peat-lite special and 15N-2.2P-12.5K CalMag special) at 100-mg·L-1 total nitrogen, and three irrigation cycles [sub-irrigation every day (wet), every third day …

Acclimation of plants with an abiotic stress can impart tolerance to some biotic stresses. Such a priming response has not been widely studied. In particular, little is known about enhanced defense capacity of drought stress acclimated plants to fungal and bacterial pathogens. Here we show that prior drought acclimation in Nicotiana benthamiana plants imparts tolerance to necrotrophic fungus, Sclerotinia sclerotiorum, and also to hemi-biotrophic bacterial pathogen, Pseudomonas syringae pv. tabaci. S. sclerotiorum inoculation on N. benthamiana plants acclimated with drought stress lead to less disease-induced cell death compared to non-acclimated plants. Furthermore, inoculation of P. syringae pv. tabaci on N. …
Light Level Does Not Alter Ethylene Sensitivity In Radish Or Pea, Joseph F. Romagnano, Bruce Bugbee
Light Level Does Not Alter Ethylene Sensitivity In Radish Or Pea, Joseph F. Romagnano, Bruce Bugbee

Ethylene accumulation occurs in many plant growth environments. In some instances, low photosynthetic photon flux (PPF) is also a stress factor. Ethylene helps regulate the shade-avoidance mechanism and synthesis rates can be altered by light. We thus hypothesized that ethylene sensitivity in whole plants may be altered in low light. Radish (Raphanus sativus) and pea (Pisum sativum) plants were selected as models due to their rapid growth, use in previous studies and difference in growth habit. We first characterized radish and pea sensitivity to ethylene. Radish vegetation was less sensitive to ethylene than pea vegetation. Pea reproductive yield was highly …
