42 results about "Trichome" patented technology

Trichomes (/ˈtraɪkoʊmz/ or /ˈtrɪkoʊmz/), from the Greek τρίχωμα (trichōma) meaning "hair", are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent.

Application of ZaSPL7 gene in regulation and control of hairy body and parthenocarpy of plant

The invention discloses application of a ZaSPL7 gene in regulation and control of hairy bodies and parthenocarpy of plants, and belongs to the technical field of gene engineering. The gene ZaSPL7 for regulating and controlling organ development of the green prickleyash is separated from cDNA of the green prickleyash and is overexpressed in a plant, the number and density of epidermal hair of the transgenic plant are obviously increased, meanwhile, the number of fruit seeds is obviously reduced, even part of plants have seedless fruit phenotypes, and the unisexual setting rate is increased. The results show that the green prickleyash SPL7 gene may coordinate epidermal hair and fruit development by integrating development stage signals, and has important application value in regulation and control of epidermal appendages (such as thorns and hair) formation and apomixis, and the mechanism provides a new idea for simultaneous improvement of plant stress resistance (by reducing the thorns) and fruit commodity (by seedless). Important theoretical basis and technical support are provided for breeding of the green prickleyash, and the method has a wide application prospect.

Application of cucumber CsLSGT gene as target spot in regulation and control of formation of silicification layer on fruit gland hair surface

The invention discloses an application of a cucumber CsLSGT gene as a target spot in regulating formation of a silicification layer on the surface of a fruit gland hair. The formation of the silicification layer on the surface of the cucumber gland hair is reduced by reducing the expression quantity of the CsLSGT gene. It is found through screening that the cucumber CsLSGT gene is related to formation of a silicification layer on the cucumber fruit gland hair surface. In a cucumber mutant, the silicon element content of fruit glandular hair is obviously reduced compared with that of a wild type '649'. Meanwhile, a grafting experiment shows that the function of the CsLSGT gene depends on the overground part, which indicates that the reduction of the silicon element on the surface of the glandular hair is mediated by an overground part factor. The gene can be used for screening cucumber fruits with few silicon elements and improving the commodity quality traits of the cucumber fruits.

A plant trichome isolation apparatus

This invention relates to the field of trichome separation equipment technology, and more particularly to a plant trichome separation device. The technical solution includes a box, a fixing frame, and a separation assembly. An inlet pipe is fixedly installed on the left side of the box, extending into the interior of the box. A recycling bin is slidably installed on one side of the bottom of the box. This invention uses a hollow, cone-like roller structure to tumble the plants, allowing them to roll and separate internally while gradually moving to one side. After separation, the plants automatically move to the waste bin for discharge, preventing the accumulation of large amounts of plant material from affecting subsequent separation. Furthermore, by adjusting the roller's rotation speed, the separation effect of the trichomes can be adjusted through centrifugal force. By introducing high-pressure gas or refrigerant into the plastic film and mounting base, the plastic film expands, opening the cone-shaped roller to contact the plants, increasing the friction on the plant surface, thereby promoting efficient trichome separation.
