Overexpression of ca1pase Decreases Rubisco Abundance and Grain Yield in Wheat.

abstract：:We understand few details about how the arrangement and interactions of cell wall polymers produce the mechanical properties of primary cell walls. Consequently, we cannot quantitatively assess if proposed wall structures are mechanically reasonable or assess the effectiveness of proposed mechanisms to change mechanic...
