Abstract The C-repeat binding factor (CBF) is crucial for regulation of cold response in higher plants. In Arabidopsis , the mechanism CBF3-caused growth retardation still unclear. Our present work shows that CBF3 shares similar repression bioactive gibberellin (GA) as well upregulation DELLA proteins with CBF1 and -2 . Genetic analysis reveals DELLAs play an essential role reduction mediated by CBF1, -2, -3 genes. vivo vitro evidences demonstrate GA2-oxidase 7 gene a novel regulon....
Drought is a major abiotic stress that impairs plant growth and development. Despite this, comprehensive understanding of drought effects on the photosynthetic apparatus lacking. In this work, we studied consequences 14-d treatment Arabidopsis thaliana. We used biochemical spectroscopic methods to examine membrane composition functionality. led disassembly PSII supercomplexes degradation core. The light-harvesting complexes (LHCII) instead remain in but cannot act as an antenna for active...
Two transgenic rice (Oryza sativa L.) lines, KMD1 and KMD2 at the R4 generation, transformed with a synthetic cry1Ab gene from Bacillus thuringiensis Berliner, were first evaluated for stem borer resistance in field during growing season of 1998 two areas Zhejiang Province, China. Both highly resistant to borers Chilo suppressalis (Walker) Scirpophaga incertulas (Walker), completely undamaged whole season. In contrast, damage plants untransformed parental control (Xiushui 11) was form...
INDUCER OF CBF EXPRESSION 1 (ICE1) encodes a MYC-like basic helix-loop-helix (bHLH) transcription factor playing critical role in plant responses to chilling and freezing stresses leaf stomata development. However, no information connecting ICE1 reproductive development has been reported. In this study, we show that controls male fertility via impacting anther dehydration. The loss-of-function mutation gene Arabidopsis caused indehiscence decreased pollen viability as well germination rate....
Damaged photosystem II reaction centers are the site of photoinhibition-related energy dissipation.
Light absorbed by chlorophylls of Photosystems II and I drives oxygenic photosynthesis. Light-harvesting complexes increase the absorption cross-section these photosystems. Furthermore, play a central role in photoprotection dissipating excess light energy an inducible regulated fashion. In higher plants, main light-harvesting complex is trimeric LHCII. this work, we used CRISPR/Cas9 to knockout five genes encoding LHCB1, which major component absence accumulation other LHCII isoforms was...
Vascular plants use carotenoids and chlorophylls a b to harvest solar energy in the visible region (400-700 nm), but they make little of far-red (FR) light. Instead, some cyanobacteria have developed ability FR light by redesigning their photosynthetic apparatus synthesizing red-shifted chlorophylls. Implementing this strategy is considered promising increase crop yield. To prepare for this, characterization light-induced changes necessary. Here, we explore behaviour Arabidopsis thaliana...
In 2003 and 2004, field studies were conducted at three sites in Zhejiang Province China to assess the impacts of Bacillus thuringiensis (Bt) Berliner rice expressing a fused gene cry1Ab cry1Ac on nontarget planthoppers leafhoppers. Populations Bt plots sampled with yellow sticky card traps, Malaise vacuum-suction machine, compared samples from non-Bt control (IR72) plots. The results trap samplings indicated no significant differences between species composition or densities each...
One major concern regarding the release of Bt rice is its potential impact through tritrophic interactions on nontarget arthropods, especially natural enemies. We studied effects two transgenic varieties, TT9- 3 and KMD1, expressing Cry1Ab/Cry1Ac Cry1Ab, respectively, a predatory ground spider [Ummeliata insecticeps (Bösenberg et Strand)] supplied with rice-fed brown planthopper [Nilaparvata lugens (Stål)] nymphs. Although immunoassays confirmed that U. ingested insecticidal protein when...
Chlorophyll fluorescence is a ubiquitous tool in basic and applied plant science research. Various standard commercial instruments are available for characterization of photosynthetic material like leaves or microalgae, most which integrate the overall signals above certain cut-off wavelength. However, wavelength-resolved (fluorescence appearing at different wavelengths having time dependent decay) contain vast information required to decompose complex processes into their underlying...
Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) catalyzes the reaction between gaseous carbon dioxide (CO2 ) and ribulose-1,5-bisphosphate. Although it is one of most studied enzymes, assembly mechanisms large hexadecameric RuBisCO still emerging. In bacteria in C4 plant Zea mays, a protein with distant homology to pterin-4α-carbinolamine dehydratase (PCD) has recently been shown be involved assembly. However, studies homologous PCD-like (RAF2, factor 2) C3 Arabidopsis thaliana (A....
We present a nonlinear spectroelectrochemical technique to investigate photosynthetic protein complexes. The PEC2DES setup combines photoelectrochemical detection (PEC) that selectively probes the photogenerated charges output with two-dimensional electronic spectroscopy (2DES) excitation spreads optical response of system in an excitation–detection map. PEC allows us distinguish contribution charge separation (CS) from other de-excitation pathways, whereas 2DES disentangle congested...

CAM plants are superior to C3 in drought resistance because of their peculiar photosynthesis pathway and morphological features. While those aspects have been studied for decades, little is known about the photosynthetic machinery plants. Here, we used a combination biochemical biophysical methods study apparatus Tillandsia flabellate, an obligatory plant. Most Photosystems super- sub-complexes properties very similar Arabidopsis, with main difference that PSI-LHCI complexes bind extra LHCI....

Transgenic rice expressing Bacillus thuringiensis Berliner (Bt) protein can effectively control target insects including stem borers and leaf folders. However, the potential effects of Bt on nontarget organisms herbivores have not been fully evaluated. In current study, ecological fitness parameters herbivore, Nephotettix cincticeps (Uhler) (Hemiptera: Cicadellidae), fed T1C-19 (Cry1C) or T2A-1 (Cry2A) were compared with non-Bt (MH63) under laboratory conditions. A 2-yr field trial was also...
A 2-yr field trial was conducted to assess the impacts of two new transgenic Bt rice lines, T1C-19 expressing Cry1C protein and T2A-1 Cry2A protein, on arthropod community sampled via vacuum. All arthropods were classified into five guilds, including herbivores, parasitoids, predators, detritivores, others. The seasonal density dominance distribution each guild community-level indices (species richness, Shannon-Wiener diversity index, Simpson evenness index) compared among types. Principal...

Photosynthesis is a fundamental process that converts photons into chemical energy, driven by large protein complexes at the thylakoid membranes of plants, cyanobacteria, and algae. In water-soluble plastocyanin (Pc) responsible for shuttling electrons between cytochrome b6f complex photosystem I (PSI) in photosynthetic electron transport chain (PETC). For an efficient turnover, transient must form PSI Pc PETC, which implies balance specificity binding strength. Here, we studied frequency...
