Abstract:
... The gene NCED1 encodes 9-cis-epoxycarotenoid dioxygenase, which catalyzes oxidative cleavage of 9-cis-epoxycarotenoids neoxanthin and violaxanthin to xanthoxin, a key step in the biosynthesis of abscisic acid (ABA) in higher plants. In the present study, the complete NCED1 of 1 917 bp was cloned and characterized from rice (Oryza sativa L. cv. N22) as no earlier reports were available for its char ...

Abstract:
... Excess radiation is one of frequent natural environmental stresses that plants have to cope with on a daily basis. Therefore, plants have evolved many short- and long-term mechanisms to acclimate to high irradiance and tolerate it. Ureides, generated from purine degradation, have been proposed as compounds involved in environmental stress responses, including altered irradiance. In the present stu ...

Abstract:
... Opaque2 is a basic leucine-zipper transcription factor that regulates the expression of several genes involved in the development of maize endosperm. Among the different mutations so far characterized, the o2Italian (o2It) allele has a genomic deletion of 10 bp that interrupts the open reading frame by a premature stop codon. Curiously, the o2It allele still encodes a long o2 isoform (o2It-L) that ...

Abstract:
... It has been hypothesized that xylanase inhibitors play important roles in plant defense against microbial pathogens. Currently, there is little information available about xylanase inhibitor OsXIP in rice and its gene expression. We cloned a xylanase inhibitor gene OsXIP from rice (Oryza sativa L. cv. Nipponbare) genomic DNA. To determine the function of OsXIP, we generated OsXIP-overexpressing tr ...
