The present invention discloses methods and apparatus for installing printed circuit boards within an electronic assembly. One embodiment of the present invention is an electro-magnetic interference shielding apparatus for an electronic assembly comprising a shielding partition that separates a first compartment from a second compartment. The apparatus further comprises a top enclosure capable of engaging with the shielding partition to form a plurality of contact seams. The contact seams are capable of restricting electro-magnetic interference from passing through the shielding apparatus. The top enclosure can be capable of tool-free installation and removal to provide access to the interior of the electronic assembly.

The plant of claim 4, wherein said male-sterility DNA encodes a ribonuclease. 16. The plant of claim 5, wherein said male-sterility DNA encodes a ribonuclease. 17. The plant of claim 8, wherein said male-sterility DNA encodes a ribonuclease. 18. The plant of claim 10, wherein said male-sterility DNA encodes a ribonuclease. 19. The plant of claim 1, wherein said male-sterility DNA encodes a barnase. 20. The plant of claim 3, wherein said male-sterility DNA encodes a barnase. 21. The plant of claim 4, wherein said male-sterility DNA encodes a barnase. 22. The plant of claim 5, wherein said male-sterility DNA encodes a barnase. 23. The plant of claim 8, wherein said male-sterility DNA encodes a barnase. 24. The plant of claim 10, wherein said male-sterility DNA encodes a barnase. 25. The plant of claim 1 or 3, wherein said male-sterility DNA encodes: a Dnase; a protease; a glucanase; a lipase, a lipid peroxidase; a cell wall inhibitor; or a bacterial toxin. 26. The plant of claim 1, wherein said male-sterility DNA encodes an enzyme which catalyzes synthesis of a phytohormone. 27. The plant of claim 1, wherein said foreign DNA further comprises a first DNA encoding a transit peptide capable of transporting said protein or polypeptide into a chloroplast or mitochondrion of said stamen cells; said first DNA being in the same transcriptional unit as said male-sterility DNA and said first promoter and between said male-sterility DNA and said first promoter. 28. The plant of any one of claims 1, 3, 12 or 14 wherein said foreign DNA further comprises: (c) a marker DNA encoding a marker RNA, protein or polypeptide which, when present at least in a specific tissue or in at least specific cells of said plant, renders said plant easily separable from other plants which do not contain said marker RNA, protein or polypeptide in said specific tissue or specific cells; and (d) a second promoter capable of directing expression of said marker DNA at least in said specific tissue or specific cells; said marker DNA being in the same transcriptional unit as, and under the control of, said second promoter. 29. The plant of claim 28, wherein said marker DNA encodes a protein inhibiting or neutralizing action of an herbicide. 30. The plant of claim 29, wherein said marker DNA is an herbicide resistance gene. 31. The plant of claim 30, wherein said marker DNA is a gene conferring resistance to a glutamine synthetase inhibitor. 32. The plant of claim 31, wherein said marker DNA is a gene conferring resistance to phosphinothricin. 33. The plant of claim 32, wherein said marker DNA is a sfr or sfrv gene. 34. The plant of claim 29, wherein said marker DNA is a gene encoding a modified target enzyme for an herbicide which (1) has a lower affinity for the herbicide and (2) is a modified 5-enolpyruvylshikimate-3 phosphate synthase as a target for glyphosate, or a modified glutamine synthetase as a target for a glutamine synthetase inhibitor. 35. The plant of claim 28, wherein said marker DNA is a gene encoding a protein or a polypeptide conferring a color to at least said specific tissue or specific cells; a gene encoding a protein or a polypeptide conferring a stress tolerance to said plant, a gene encoding a protein or a polypeptide conferring a disease or pest resistance, a gene encoding a Bacillus thuringiensis endotoxin that confers insect resistance, or a gene encoding a bactericidal peptide that confers a bacterial resistance. 36. The plant of claim 28, wherein said second promoter is: a constitutive promoter or a wound-inducible promoter. 37. The plant of claim 29, wherein said second promoter is a constitutive promoter or a promoter which directs gene expression selectively in plant tissue having photosynthetic activity. 38. The plant of claim 37, wherein said second promoter is a CaMV 35S promoter or a ribulose bisphosphate carboxylase SSU promoter. 39. The plant of claim 30, wherein said
