The control of floral organ identity by homeotic MADS box genes is well established in eudicots. However, grasses have highly specialized outer organs, and the identities that regulate organs remain unclear. In this study, we characterized a MIKC-type gene, CHIMERIC FLORAL ORGANS (CFO1), which plays key role regulation rice (Oryza sativa). cfo1 mutant displayed defective marginal regions palea, chimeric ectopic organs. Map-based cloning demonstrated CFO1 encoded OsMADS32 protein....
Abstract The spikelet is a unique inflorescence structure of grass. molecular mechanism that controls the development remains unclear. In this study, we identified rice (Oryza sativa) mutant, multi-floret spikelet1 (mfs1), showed delayed transformation meristems to floral meristems, which resulted in an extra hull-like organ and elongated rachilla. addition, sterile lemma was homeotically converted rudimentary glume body palea degenerated mfs1. These results suggest MULTI-FLORET SPIKELET1...
Significance In cereal crops, the number of florets in a spikelet is an important factor affecting grain per panicle and then yield. wild-type rice, one produces fertile floret. This study characterized gain-of-function mutant lateral 1 ( lf1 ) rice. , developed with proper floral organ identities axil sterile lemma, showing that rice has potential to restore “three-florets spikelet” which may have existed ancestors. Therefore, it provides strong evidence supporting three-florets hypothesis...
As an important agronomic trait, leaf rolling in rice (Oryza sativa L.) has attracted much attention from plant biologists and breeders. Moderate increases the amount of photosynthesis cultivars hence raises grain yield. Here, we describe map-based cloning gene RL14, which was found to encode a 2OG-Fe (II) oxygenase unknown function. rl14 mutant plants had incurved leaves because shrinkage bulliform cells on adaxial side. In addition, displayed smaller stomatal complexes decreased...
To understand the molecular mechanisms of rice aerial organ development, we identified a mutant gene that caused significant decrease in width organs, termed ABNORMAL VASCULAR BUNDLES (AVB). Histological analysis showed slender organs were by cell number reduction. In avb, vascular bundles was reduced, whereas area increased. Ploidy and situ expression patterns histone H4 confirmed proliferation impaired during lateral primordia procambium cells greater ability to undergo division avb. RNA...
The "hot exciton" thermally activated delayed fluorescence (TADF) materials have attracted considerable research interest for their utilization of high-lying triplet excitons. In this work, we reported the mechanism photoluminescence by revealing spectral evolution from singlet to states in TADF molecules transient absorption (TA) spectra and sensitization experiments. internal conversion intersystem crossing are much faster than reverse (RISC), so that (Tn) difficult accumulate be observed...
Multiresonance thermally activated delayed fluorescence (MR-TADF) emitters are excellent candidates for high-performance organic light-emitting diodes (OLEDs) due to their narrowband emission properties. However, the inherent mechanism of regulating rate intersystem crossing (ISC) is ambiguous in certain MR-TADF skeletons. Herein, we propose a accelerating ISC B/S-based by peripheral modifications electron-donating groups (EDGs) without affecting property. The long-range charge transfer...
Multi‐resonance thermally activated delayed fluorescence (MR‐TADF) materials have great potential for applications in ultrahigh‐definition (UHD) organic light‐emitting diode (OLED) displays, that benefit from their narrowband emission characteristic. However, key challenges such as aggregation‐caused quenching (ACQ) effect and slow triplet‐to‐singlet spin‐flip process, especially blue MR‐TADF materials, continue to impede development due planar skeletons relatively large ΔESTs. Here, an...

Identifying quantitative trait loci (QTL) for yield traits using single-segment substitution lines (SSSL) is essential both targeted breeding and functional analysis of key genes. Here, a wide-grain rice chromosome segment line (CSSL), Z708, carrying four segments from Jinhui35 in the genetic background Xihui18, was used to identify QTL associated with grain size. Seven yield-related ( qGW4 , qRLW4 qGWT4 qGW5 qRLW5 qGWT5 qGPP5 ) were identified on fourth fifth chromosomes Z708. Subsequently,...
Abstract Precise doping is of vital significance for atomic engineering and the establishment structure‐property relationships in nanocluster (NC) chemistry. Herein, two novel trimetallic MAu 18 Cd 3 (M = Pd/Pt) NCs that are derived from M‐doped Au 25 templates 24 reported, which central M atom surface‐motif atoms concurrently achieved. Compared to original templates, Cd‐induced surface enhances rigidity structural framework enlarges HOMO‐LUMO gaps , significantly improving photoluminescent...
Rice chromosome segment substitution lines (CSSLs) are ideal for creating natural variation and dissecting complex quantitative traits. In addition, it builds a bridge molecular breeding accurate identification of trait loci (QTLs). this study, to construct an indica rice library single-segment (SSSLs) spanning the whole genome, CSSL-Z691 carrying four segments (4.07 Mb average length) was identified by marker-assisted selection (MAS) from restorer line “Jinhui35” in “Xihui18” genetic...
The de novo synthesis of purine nucleotides is crucial to all living organisms, but limited information available for plants. In this study, we isolated a virescent-albino leaf 1 (val1) mutant rice (Oryza sativa) that produces dynamic green-revertible albino and narrow-leaf phenotypes. leaves, chloroplast development was defective, pigment contents were reduced, cell division impaired compared with the wild-type. Map-based cloning revealed VAL1 encodes phosphoribosylamine-glycine ligase...
Abstract Background Grain size affects not only rice yield but is also an important element in quality of appearance. However, the mechanism for inheritance grain unclear. Results A chromosome segment substitution line Z1392, which harbors three segments and produces grains increased length, was identified. The were located on chromosomes 1, 5, 6, average length 3.17 Mb. Cytological analysis indicates that predominant cause Z1392 could be cell expansion glumes. Seven quantitative trait loci...
Abstract Leaf morphology is one of the most important features ideal plant architecture. However, genetic and molecular mechanisms controlling this feature in crops remain largely unknown. Here, we characterized rice (Oryza sativa) wide leaf 1 (wl1) mutant, which has wider leaves than wild-type due to more vascular bundles greater distance between small bundles. WL1 encodes a Cys-2/His-2-type zinc finger protein that interacts with Tillering Dwarf (TAD1), co-activator anaphase-promoting...
A dynamically rolled leaf mutant (rl10) was identified from a spontaneous mutation in an Oryza sativa L. subsp. indica line, II-32B. The chlorophyll content of rl10 is higher than that the wild type. Genetic analysis using 3 F2 segregating populations derived crosses between and rice lines Mian5B, II-32B, D62B, respectively, confirmed trait controlled by single recessive gene. Of 719 SSR primer pairs showed polymorphism D62B rl10, 151 were adopted to map RL10(t) gene population cross x which...
Abstract Background Chromosome segment substitution lines (CSSLs) can be used to dissect complex traits, from which single-segment (SSSLs) containing a target quantitative trait loci (QTL) developed, and they are thus important for functional analysis molecular breeding. Results A rice line with short wide grains, CSSL-Z563, was isolated advanced-generation backcross population (BC 3 F 6 ) derived ‘Xihui 18’ (the recipient parent) ‘Huhan 3’ donor parent). Z563 carried seven segments 3’,...
