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 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...
Zebra leaf mutants are an important resource for studying colour in rice. In most such mutants, the zebra phenotype results from defective chloroplast biogenesis. The molecular mechanism by which leaves develop remains unclear, so additional zebra-leaf need to be identified.We isolated a novel rice mutant, named 15 (z15), showed transversely striped with yellow-green or white-green sectors, structure was disturbed. Transmission electron microscopy revealed that of various organelles impaired...
Abstract As the basic unit of rice ( Oryza sativa L.) inflorescence, spikelet has a profound influence on grain size, weight, and yield. However, molecular mechanism that underlies development spikelets never been fully elucidated. In this study, we characterized mutant, multi‐grains 1 mg1 ), which was derived from treatment ‘Xinong 1B’ with ethyl methanesulfonate. developed two florets an extra lemma‐like organ increased number inner floral organs. Notably, could produce multi‐grains. These...
<p indent=0mm>The important agronomic traits, such as grain type, plant height, and panicle composition, are closely related to rice yield, their gene inheritance is complex. Chromosome segment substitution lines (CSSLs) useful materials for studying these complex traits. An excellent CSSL, Z746, containing seven segments with an average length of 3.99 Mb, was identified from Nipponbare a recipient ‘Xihui 18’ donor parent. There were significant differences in composition size between Z746...
The motion detection of birds around airports is a fundamental assignment for preventing bird strikes. With the growth image processing algorithms, optical radar can achieve like electromagnetic radar. Unfortunately, with restriction position in airports, change illumination, and influence bad weather, captured by unclear lose detail color texture. In this paper, multiple methods, such as flow, background subtraction, frame difference, are proposed modified to implement control airports. We...
The spikelet is a unique inflorescence structure in grasses. However, the molecular mechanism that regulates its development remains unclear, and we therefore characterize mutant of rice (Oryza sativa L.), aberrant-floral 1 (afs1), which was derived from treatment Xinong 1B with ethyl methanesulfonate. In afs1 mutant, developed an additional lemma-like organ alongside other normally floral organs, paleae were degenerated to differing degrees or without inner organs. Genetic analysis revealed...
Abstract Leaf morphology is one of the most important features ideal plant architecture. However, genetic and molecular mechanisms controlling leaf in crops remain largely unknown, despite their central importance. Here we demonstrate that APC/C TAD1 -WL1-NAL1 pathway regulates width rice, mutation WL1 leads to variation. interacts with degraded by , loss function resulting narrow leaves. The protein directly binds regulatory region NAL1 recruits corepressor TOPLESS-RELATED PROTEIN inhibit...
