Histological changes of the anthers during anther development in LYPJ and SY63 plants. A, B, C, and D show anther cross-sections at stage 8b. E, F, G, and H show anther cross-sections at stage 9. I, J, K, and L show anther cross-sections at stage 11. M, N, O, and P show anther cross-sections at stage 13. Ep, epidermis; En, endothecium; Msp, microspores; Ta, tapetal layer; Mp, mature pollen; Vt, vascular tissue; Ct, connective tissue; St, stomium. Scale bars = 50 μm. CK, control temperature; HT, high temperature
