Genome-wide identification, structure characterization, and expression pattern profiling of aquaporin gene family in cucumber.

Background: Aquaporin (AQP) proteins comprise a group of membrane intrinsic proteins (MIPs) that are responsible for transporting water and other small molecules, which is crucial for plant survival under stress conditions including salt stress. Despite the vital role of AQPs, little is known about them in cucumber (Cucumis sativus L.).

Identification of cucumber circular RNAs responsive to salt stress.

Background: Circular RNAs (circRNAs) are 3'-5' head-to-tail covalently closed non-coding RNA that have been proved to play essential roles in many cellular and developmental processes. However, no information relate to cucumber circRNAs is available currently, especially under salt stress condition.

Results: In this study, we sequenced circRNAs in cucumber and a total of 2787 were identified, with 1934 in root and 44 in leaf being differentially regulated under salt stress.

Ethyl 7-(2-chloro-phen-yl)-5-trifluoro-meth-yl-4,7-dihydro-1,2,4-triazolo[1,5-a]pyrimidine-6-carboxyl-ate.

In the title compound, C(15)H(12)ClF(3)N(4)O(2), the dihydro-pyrimidine ring exhibits an envelope conformation. The dihedral angle between the mean planes of the dihydro-pyrimidine and phenyl rings is 83.94 (6)°.

5-Amino-7-(4-bromo-phen-yl)-3,7-di-hydro-2H-thieno[3,2-b]pyran-6-carbo-nitrile 1,1-dioxide.

In the title compound, C(14)H(11)BrN(2)O(3)S, the 2,3-dihydro-thio-phene ring is almost planar [maximum deviation = 0.006 (1) Å]. The pyran ring is in an envelope conformation [puckering parameters Q = 0.

3-Ethyl 5-methyl 2-hydr-oxy-6-methyl-4-(4-nitro-phen-yl)-2-trifluoro-methyl-1,2,3,4-tetra-hydro-pyridine-3,5-dicarboxyl-ate.

In the title compound, C(18)H(19)F(3)N(2)O(7), the tetrahydropyridine ring adopts a half-chair conformation. The nitro group is disordered over two sites with occupancies of 0.780 (15) and 0.
