Effects of intentionally treated water and seeds on the growth of Arabidopsis thaliana.

Objective: . A previously reported experiment indicated that Arabidopsis thaliana seeds with cryptochrome mutation His-CRY2 showed more robust photomorphogenic growth when hydrated with intentionally treated water as compared to untreated water. The present study attempted to replicate that outcome, adding a condition where the seeds were also intentionally treated.

FIN219/JAR1 and cryptochrome1 antagonize each other to modulate photomorphogenesis under blue light in Arabidopsis.

Plant development is affected by the integration of light and phytohormones, including jasmonates (JAs). To address the molecular mechanisms of possible interactions between blue light and JA signaling in Arabidopsis thaliana, we used molecular and transgenic approaches to understand the regulatory relationships between FAR-RED INSENSITIVE 219 (FIN219)/JASMONATE RESISTANT1 (JAR1) and the blue-light photoreceptor cryptochrome1 (CRY1). FIN219 overexpression in the wild type resulted in a short-hypocotyl phenotype under blue light.

Effects of Intentionally Treated Water on Growth of Arabidopsis thaliana Seeds with Cryptochrome Mutations.

Objective: A previous experiment suggested that consumption of intentionally treated tea influenced subjective mood under double-blind, controlled conditions. To investigate that effect objectively, again under double-blind, controlled conditions, we studied whether Arabidopsis thaliana seeds hydrated with intentionally treated vs. untreated water would show differences in hypocotyl length, anthocyanin, and chlorophyll.

Far-Red Light-Mediated Seedling Development in Arabidopsis Involves FAR-RED INSENSITIVE 219/JASMONATE RESISTANT 1-Dependent and -Independent Pathways.

Plant growth and development is often regulated by the interaction of environmental factors such as light and various phytohormones. Arabidopsis FAR-RED INSENSITIVE 219 (FIN219)/JASMONATE RESISTANT 1 (JAR1) participates in phytochrome A-mediated far-red (FR) light signaling and interacts with different light signaling regulators. FIN219/JAR1 is a jasmonic acid (JA)-conjugating enzyme responsible for the formation of JA-isoleucine.

Identification of microRNA 395a in 24-epibrassinolide-regulated root growth of Arabidopsis thaliana using microRNA arrays.

Brassinosteroids (BRs) are endogenous plant hormones and are essential for normal plant growth and development. MicroRNAs (miRNAs) of Arabidopsis thaliana are involved in mediating cell proliferation in leaves, stress tolerance, and root development. The specifics of BR mechanisms involving miRNAs are unknown.

New gene construction strategy in T-DNA vector to enhance expression level of sweet potato sporamin and insect resistance in transgenic Brassica oleracea.

Sporamin, an abundant storage protein in tuberous roots of sweet potato, possesses strong inhibitory activity against trypsin and pest-resistance. To promote consistent high-level expression of sporamin and insect resistance in transgenic Brassica plants, a wound-responsive sporamin promoter (Pspoa) alone or combined with matrix-attached-region-like DNA segment (spoMAR) were constructed for driving sporamin cDNA. The results showed the transgenic plants containing Pspoa-drived sporamin and spoMAR displayed the highest level and low inter-transformant variability of sporamin expression, and the ability of insect resistance of transformants positively correlated with sporamin activity.
