N-(2-Chloro-4-pyridyl)-N'-phenylurea (CPPU) is a highly active cytokinin-like plant growth regulator that promotes chlorophyll biosynthesis, cell division, and cell expansion. It also increases fruit set and accelerates fruit enlargement. However, there has been no report about the effect of CPPU on fruit development and its physiological mechanism in macadamia. In this study, we investigated t...

In the title compound, C(16)H(17)ClN(4)O(2), the aromatic ring is twisted slightly with respect to the plane of the diazene group [N-N-C-C torsion angle = -3.9 (4)°]. The NO(2) group is twisted by 16.2 (4)° relative to the aromatic ring. The two ethyl chains are positioned such that one ethyl chain lies above and the other below the ring.

To understand the molecular mechanisms that control seed formation, we selected a seed-preferential gene (CvADH1) from the ESTs of developing watermelon seeds. RNA blot analysis and in situ localization showed that CvADH1 was preferentially expressed in the nucellar tissue. The CvADH1 protein shared about 50% homology with short-chain alcohol dehydrogenase including ABA2 in Arabidopsis thaliana...

In the title compound, C(13)H(11)Cl(2)NO(2)S, the conformations of the N-C bonds in the C-SO(2)-NH-C segment have gauche torsions with respect to the S=O bonds. Further, the conformation of the N-H bond is syn to the ortho-methyl group in the sulfonyl benzene ring. The torsion angle of the C-SO(2)-NH-C segment in the mol-ecule is 55.0 (2)°. The two benzene rings are tilted relative to each othe...
