The present invention relates to the field of plant breeding and in particular to the regeneration of plants from cells and other tissues. More particularly, the invention provides methods and means for improving callus and shoot formation and regeneration of plants using hyperphyllin or derivatives thereof.

This disclosure provides a stress-responsive polypeptide sequence for fusion with a polypeptide to specifically induce stability of the fusion polypeptide under stress conditions, such as drought, high salt and high temperature, in plants. Also disclosed includes an expression vector for expressing a fusion polypeptide comprising the stress-responsive peptide in plants transformed therewith, and a method for generating a transgenic plant with enhanced tolerance to environmental stresses, comprising introducing into the transgenic plant a polynucleotide encoding a fusion polypeptide which comprises the stress-responsive peptide as disclosed and a plant anti-stress gene, such as the plant senescence-associated gene SSPP. A plant expressing the expression vector that have an enhanced stress tolerance, including Arabidopsis and soybean, is also provided.

The present disclosure relates to settling devices for separating particles from a bulk fluid with applications in numerous fields. The particle settling devices of the present disclosure may include a stack of truncoconical cones that may be arranged in opposite orientation, apex to base. Other embodiments include several concentric vertical tubes attached to conical surfaces at the bottom, with inclined settling strips attached to the vertical tubes in annular regions between the tubes. These devices are useful for separating small (millimeter or micron sized) particles from a bulk fluid with applications in numerous fields, such as biological (microbial, mammalian, plant, insect or algal) cell cultures, solid catalyst particle separation from a liquid or gas and waste water treatment.

The invention relates to a Canola hybrid variety designated 1CN0152, essentially derived variants of that Canola hybrid variety, to the seeds, plants, and plant parts of this Canola hybrid variety 1CN0152. The invention also relates to methods for producing a canola plant containing in its genetic material one or more traits introgressed into 1CN0152 through backcross conversion and/or transformation, and to the Canola seed, plant and plant part produced thereby.

Provided is a method of producing plant embryos having improved embryo quality or germination frequency comparing to embryos developed by conventional methods. The method entails the steps of (a) incubating plant embryogenic suspensor mass (ESM) in, or on, a standard development medium supplied with glucose for a first incubation period to develop immature somatic embryos; (b) mass transferring the immature somatic embryos to a modified development medium near or at cotyledon stage; and (c) incubating the immature somatic embryos in, or on, the modified development medium for a second incubation period to develop mature somatic embryos. The modified development medium contains reduced concentration of glucose or is glucose-free and the osmolality of the modified development medium is adjusted to compensate for the loss of osmolality due to reduction or removal of glucose.

Provided herein are double flowered New Guinea Impatiens cultivars comprising rippled, twisted, incurved petals. Methods for breeding the disclosed Impatiens are also provided.

The present disclosure describes a DNA fragment mixture for the prevention or for the treatment of at least one pathogenic, parasitic or infesting species of plants or of the environment, wherein the DNA mixture consists of random fragments of total DNA of at least one pathogenic, parasitic, or infesting species, and/or at least one phylogenetically similar species, against which the prevention and treatment are directed. Further, the disclosure describes a process and related system for improvement of the production/growth of microorganisms at high yield in bioreactors or photobioreactors, or of plants in different culture systems, where the nucleic acids of the organisms produced/grown by such a process are removed from the culture medium and the culture medium, deprived of these nucleic acid, is used again in the process.
