Abstract: An LED lighting device includes a seat, an optical assembly and a light source. The seat has a baseplate and a sidewall. A chamber is formed between the baseplate and the sidewall. The optical assembly completely covers a light-emitting side of the LED lighting device. The light source is disposed in the chamber of the seat and includes multiple LED arrays. Each LED array includes an LED chip. The optical assembly includes an optical unit. The optical unit includes multiple first optical members and multiple second optical members corresponding to the first optical members. The LED arrays correspond to the first optical members. Each first optical member possesses an effect of light diffusion resulting from its own material property. Each second optical member includes one or more sets of optical walls. Each set of optical walls surrounds one of the first optical members.

Abstract: The present invention generally relates to methods and materials involved in producing tobacco plants having reduced levels of conversion of nicotine to nornicotine. In certain embodiments, the invention is directed to mutations in a nicotine demethylase gene, tobacco plants comprising mutations in a nicotine demethylase gene, and tobacco compositions and products thereof. In other embodiments, the invention is directed toward nicotine demethylase RNA interference, tobacco plants comprising a nicotine demethylase RNA interference transgene, and tobacco compositions and products thereof.

Abstract: Provided herein are genetic markers and a coding sequence associated with a low- or ultra-low anatabine trait in tobacco.

Abstract: The present disclosure includes methods and compositions for improving leaf quality in low-alkaloid tobacco plants, e.g., by combining inducible promoters and non-coding RNAs for suppression of an ornithine decarboxylase (ODC) gene. Also provided are low alkaloid tobacco plants with normal, suppressed, or otherwise altered polyamine levels. Further provided are tobacco plants with altered total alkaloid, nicotine levels, commercially acceptable leaf grade, their development via breeding or transgenic approaches, and production of tobacco products from these tobacco plants.

Abstract: The present disclosure provides tobacco Nic1b locus and associated genes (e.g., a group of ERF genes). Also provided are tobacco plants with altered total alkaloid and nicotine levels and commercially acceptable leaf grade, their development via breeding or transgenic approaches, and production of tobacco products from these tobacco plants. Further provided are compositions and methods for producing tobacco plants having novel mutations or alleles to reduce nicotine levels. Further provided are sequence polymorphisms and molecular markers for breeding tobacco with reduced nicotine or alkaloids while maintaining tobacco leaf grade and tobacco product quality.
