Abstract Chlorophyll biosynthesis must be tightly coupled to light-harvesting chlorophyll a/b-binding protein (LHCP) biogenesis, as free and its precursors are phototoxic. However, precisely how these 2 processes coordinated in Arabidopsis (Arabidopsis thaliana) remains elusive. Our previous studies demonstrated the role of LHCP TRANSLOCATION DEFECT (LTD) delivering LHCPs chloroplast via signal recognition particle-dependent pathway. Here, we show that LTD interacts with stabilizes enzymes...
Male sterility is a valuable trait for genetic research and production application of wheat (Triticum aestivum L.). NWMS1, novel typical genic male mutant, was obtained from Shengnong 1, mutagenized with ethyl methane sulfonate (EMS). Microstructure ultrastructure observations the anthers microspores indicated that pollen abortion NWMS1 started at early uninucleate microspore stage. Pollen grain collapse, plasmolysis, absent starch grains were three characteristics abnormal microspores. The...
Tillers not only determine plant architecture but also influence crop yield. To explore the miRNA regulatory network restraining tiller development in a dwarf-monoculm wheat mutant (dmc) derived from Guomai 301 (wild type, WT), we employed miRNome and transcriptome integrative analysis, real-time qRT-PCR, histochemistry, determinations of key metabolites photosynthesis parameters. A total 91 differentially expressed miRNAs (DEMs) were identified between dmc WT. Among them, 40 DEMs targeted...
Complete differentiation of the spikes guarantees final wheat (Triticum aestivum L.) grain yield. A unique mutant that prematurely terminated spike (ptsd1) was obtained from cultivar Guomai 301 treated with ethyl methane sulfonate (EMS). The molecular mechanism study on ptsd1 showed senescence-associated genes (SAGs) were highly expressed, and related homeotic depressed. Cytokinin signal transduction weakened ethylene enhanced. enhanced expression Ca2+ accumulation reactive oxygen species...
Spotted leaf (spl) mutant is a type of lesion mimic mutants in plants. We obtained some from ethyl methane sulfonate (EMS)-mutagenized wheat (Triticum aestivum L.) cultivar Guomai 301 (wild type, WT), and one them was named as white stripe (wsl) because the stripes on its leaves. Here we report heredity gene mapping this novel wsl. There are many small scattered leaves wsl throughout whole growth period. As plants grew, became more severe necrotic area expanded. The grew only weakly before...
A dwarf, multi-pistil and male sterile dms mutant was previously reported by us. However, the genetic changes in this are unclear. To examine changes, single nucleotide polymorphism (SNP) association, chromosome counting, high-resolution fluorescence situ hybridization (FISH) techniques were employed. By comparing tall plants (T) with dwarf (D) offspring of plants, SNP association analysis indicated that most SNPs on 2A. There three types 42, 41 40 chromosomes respectively. High-resolution...
