Material characterization of engineered silk material for in planta applications. a) Solubility of Cs–silk fibroin blends (Cs_xxSF_yy) in simulated sap fluid. Cs dramatically increases the solubility of CsSF blends, resulting in materials that can easily biodegrade in a sap‐like environment. b) CD spectra of CsSF blends with various Cs content. c) Mechanical properties of CsSF films with various Cs content under tension. d) Hydrogen peroxide preservation in SF, Cs₁₀SF₉₀, and Cs₂₀SF₈₀. e) HRP preservation in SF, Cs₁₀SF₉₀, and Cs₂₀SF_80. f) Agrobacterium preservation in SF and Cs₂₀SF₈₀. Data are mean ± s.d (n is at least 3).
