A plant promoter being tissue specific for endosperm and embryo of a plant seed

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a plant promoter sequence that enables tissue-specific expression of proteins in the endosperm and, especially, the epidermis of the embryo in plant seeds. By using this promoter in genetic constructs, researchers or developers can ensure that desired genes are expressed specifically in these seed tissues, allowing targeted modification of seed traits. Such specificity is particularly useful for improving commercially important seed components such as oils, starch, and biosynthetic products.

Use CasesContent extracted from patent full text and abstract with AI.

• Selective enhancement of oil, fat, or lipid production in seeds of crops like rapeseed, sunflower, soybean, or pumpkin.
• Targeted delivery of nutritional or pharmacologically active compounds in seeds for food, feed, or pharmaceutical uses.
• Production of seeds with improved nutrient content by expressing transporters or biosynthetic enzymes only in seed endosperm and embryo.
• Research in plant developmental biology to study the function of specific genes during seed development by controlling where they are expressed.
• Generation of transgenic seeds specifically expressing resistance or protective proteins in the seed tissues without affecting the rest of the plant.

BenefitsContent extracted from patent full text and abstract with AI.

• Highly tissue-specific expression minimizes off-target effects and unwanted gene expression in non-seed tissues.
• Improves efficiency and yield of desired seed compounds (like oils or nutrients) by focusing modification on relevant seed tissues.
• Reduces potential side effects on plant growth or physiology that could arise from whole-plant gene expression.
• Facilitates creation of value-added crops with enhanced traits targeted to seeds, which are the main economic or nutritional product.
• Enables more precise studies and engineering of seed development and metabolism.
