Fig. 4From: Abnormal anther development leads to lower spikelet fertility in rice (Oryza sativa L.) under high temperature during the panicle initiation stageHistological 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.
