2,2,2-Trichloro-N-(3-nitro-phen-yl)acetamide.

In the title compound, C(8)H(5)Cl(3)N(2)O(3), the dihedral angle between the nitro-phenyl ring and the acetamide group is 5.47 (6)°. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into chains running parallel to the b axis.

Differential response of tomato and tobacco to Agrobacterium mediated transformation with cytokinin independent -1 (CKI-1) gene as influenced by cytokinin levels.

Cytokinin independent-1 (CKI-1) gene was identified through its ability to confer cytokinin independent growth in Arabidopsis which has led to this gene being advocated as a selectable marker in plant transformation. Keeping this in view, CKI-1 gene was assessed as a selectable marker by transformation of tobacco (Nicotiana tabacum) and tomato (Lycopersicon esculentum L.).

Synthesis, characterization and antimicrobial activity of some disubstituted 1,3,4-oxadiazoles carrying 2-(aryloxymethyl)phenyl moiety.

Disubstituted 1,3,4-oxadaiazoles (4a-z, 4a'-f'), Mannich bases (6a-p) and S-alkylated derivatives (7a-t) have been synthesized from 2-(aryloxymethyl)benzoic acids (1a-d) through a multi-step reaction sequence. The structures of new compounds were established on the basis of their elemental analyses, IR, (1)H NMR, (13)C NMR and mass spectral data. All the synthesized compounds were screened for their in vitro antibacterial and antifungal activity and some of them exhibited good activity.
