Abstract:
A plant comprising a foreign DNA incorporated into the nuclear genome of its cells, said foreign DNA comprising:(a) a fertility-restorer DNA encoding a restorer protein or polypeptide; and(b) a first promoter directing expression of said fertility-restorer DNA at least in specific stamen cells of said plant, said fertility-restorer DNA being in the same transcriptional unit as, and under the control of, said first promoter;wherein said plant, when crossed to a male-sterile plant having a sterility DNA in its nuclear genome and an activity of selectively producing a sterility protein in specific stamen cells so as to kill or disable said cells, produces progeny comprising said sterility DNA and said fertility-restorer DNA, andwherein said progeny are male fertile due to neutralization, blocking, prevention or inhibition of the activity of said sterility protein by said restorer protein or polypeptide.
