Metabolite diffusion into bundle sheath cells from c(4) plants: relation to c(4) photosynthesis and plasmodesmatal function.

abstract：:The emergence of sterile individuals in the hybrid backcross progeny of wild and cultivated rice limits the use of wild rice alleles for improving cultivated rice, but the molecular mechanisms underlying this sterility remain unclear. Here, we identified the semisterile introgression line YIL42, derived from a cross b...
