!--[if gte mso 9]> In plants, class III T2 RNases involve two groups ofstructurally similar proteins, but with different biological functions:S-RNases and non-S-RNases. S-RNases have been involved in self-incompatibilitywhile non-S-RNases have been implicated in stress responses. Here we report anovel class III RNase gene termed NaPi/Sx-RNase,which works both in self-incompatibility and in response to phosphatedeficiency. The NaPi/Sx-RNasewas identified  in roots of Nicotiana alata grown in the absence ofinorganic phosphate. Phylogenetic analysis showed that NaPi/Sx-RNase was included within the cl
