WebbAphids are small insects which feed by inserting their very fine mouthparts (stylets) into plant tissue, where they feed on cell sap (Fig. 1 A + B). As an aphid inserts its stylets into plant tissue it secretes a stylet sheath around the stylets (Fig. 2 A + B). When the stylets are withdrawn the stylet sheath remains in the tissues of the plant ... Webb7 apr. 2024 · Phloem sap transport is essential for plant nutrition and development since it mediates redistribution of nutrients, metabolites and signaling molecules. However, its biochemical composition is not so well-known because phloem sap sampling is difficult and does not always allow extensive chemical analysis. In the past years, efforts have …
