Constitutive overexpression of the calcium sensor CBL5 confers osmotic or drought stress tolerance in Arabidopsis
Calcium serves as a critical messenger in many adaptation and developmental processes. Cellular calcium signals are detected and transmitted by sensor molecules such as calcium-binding proteins. In plants, the...

Isolation and characterization of a novel rice Ca2 +-regulated protein kinase gene involved in responses to diverse signals including cold, light, cytokinins, sugars and salts
We have isolated a cold-inducible gene (designated OsCK1) from Oryza sativa by a differential cDNA screening technique. Sequence analysis indicated that the open reading frame of the OsCK1 gene consists of 1350 b...

Identification of Mutator insertional mutants of starch-branching enzyme 1 (sbe1) in Zea mays L.
Starch-branching enzymes (SBE) alter starch structure by breaking an α-1,4 linkage and attaching the reducing end of the new chain to a glucan chain by an α1,6 bond. In maize, three isoforms of SBE have been i...

Molecular cloning and characterization of the Amylose-Extender gene encoding starch branching enzyme IIB in maize
The amylose-extender (Ae) gene encoding starch-branching enzyme IIb (SBEIIb) in maize is predominantly expressed in endosperm and embryos during kernel development. A maize genomic DNA fragment (−2964 to +20 4...

Separation of cis elements responsive to ethylene, fruit development, and ripening in the 5′-flanking region of the ripening-related E8 gene
The E8 gene is expressed at a high level during fruit ripening, and is transcriptionally activated by ethylene. We have identified a 428 bp fragment of the E8 5'-flanking region, from -1528 to -1100, that make...

Evolutionary conservation and expression patterns of maize starch branching enzyme I and IIb genes suggests isoform specialization
Expression of the maize (Zea mays L.) starch branching enzyme (SBE) genes Sbe1 and Sbe2 were characterized during kernel development and in vegetative tissues. The onset of Sbe1 and Sbe2 expression during endospe...

Two closely related cDNAs encoding starch branching enzyme from Arabidopsis thaliana
Two starch branching enzyme (SBE) cDNAs were identified in an Arabidopsis seedling hypocotyl library using maize Sbe1 and Sbe2 cDNAs as probes. The two cDNAs have diverged 5′ and 3′ ends, but encode proteins whic...
