Maize (Zea mays) floury3 (fl3) is a classic semidominant negative mutant that exhibits severe defects in the endosperm but fl3 plants otherwise appear normal. We cloned gene and determined it encodes PLATZ (plant AT-rich sequence zinc binding) protein. The mutation resulted an Asn-to-His replacement conserved domain, creating dominant allele. Fl3 specifically expressed starchy cells regulated by genomic imprinting, which leads to suppressed expression of when transmitted through male,...
Abstract Grain filling in maize (Zea mays) is regulated by a group of spatiotemporally synchronized transcription factors (TFs), but the that coordinate their expression remain unknown. We used promoter grain filling-specific TF gene Opaque2 (O2) to screen upstream regulatory and identified B3 domain TF, ZmABI19, directly binds O2 for transactivation. zmabi19 mutants displayed developmental defects endosperm embryo, mature kernels were opaque reduced size. The accumulation zeins, starch...
Abstract Dent and flint kernel architectures are important characteristics that affect the physical properties of maize kernels their grain end uses. The genes controlling these traits unknown, so it is difficult to combine advantageous both. We found mutation ARFTF17 in a dent genetic background reduces IAA content seed pericarp, creating flint-like phenotype. highly expressed pericarp encodes protein interacts with inhibits MYB40, transcription factor dual functions repressing PIN1...
Significance More than half a century ago, Oliver Nelson and Edwin Mertz at Purdue University found the maize opaque2 ( o2 ) mutation produces doubling of endosperm lysine content, creating foundation for quality protein (QPM) breeding. QPM has potential to benefit millions people in developing countries who consume as their sole source. However, breeding new hybrids takes longer regular hybrids, primarily because complex unknown components modification; this limited expansion worldwide. We...
Summary The endosperm‐specific transcription factor Opaque2 (O2) acts as a central regulator for endosperm filling, but its functions have not been fully defined. Regular o2 mutants exhibit non‐vitreous phenotype, so we used vitreous variety Quality Protein Maize to create EMS‐mutagenesis screening enhancers ( oen ). A mutant oen1 ) restored non‐vitreousness and produced large cavity in the seed due severely depleted filling. When was introgressed into inbred W64A with normal O2 gene, seeds...
Abstract The mechanism that creates vitreous endosperm in the mature maize kernel is poorly understood. We identified Vitreous 1 ( Ven1 ) as a major QTL influencing this process. encodes β-carotene hydroxylase 3, an enzyme modulates carotenoid composition amyloplast envelope. A619 inbred contains nonfunctional allele, leading to decrease polar and increase non-polar carotenoids amyloplast. Coincidently, stability of membranes increased during desiccation. lipid cells altered, giving rise...
Opaque2 (O2) functions as a central regulator of the synthesis starch and storage proteins O2 gene is transcriptionally regulated by hub coordinator seed development grain filling, ABSCISIC ACID INSENSITIVE 19 (ZmABI19), in maize (Zea mays). Here, we identified second coordinator, basic Leucine Zipper 29 (ZmbZIP29) that interacts with ZmABI19 to regulate expression. Like zmabi19, zmbzip29 mutations resulted dramatic decrease transcript protein levels thus significant reduction proteins....
Abstract Maize kernels are complex biological systems composed of three genetic sources, namely maternal tissues, progeny embryos, and endosperms. The lack gene expression profiles with spatial information has limited the understanding specific functions each cell population, hindered exploration superior genes in kernels. In our study, we conduct microscopic sectioning transcriptomics analysis during grain filling stage maize This enables us to visualize patterns all through electronical...
PLATZ proteins are a novel class of plant-specific zinc-dependent DNA-binding that classified as transcription factors (TFs). However, their common biochemical features and functions poorly understood. Here, we identified cloned 17 genes in the maize (Zea mays) genome. All ZmPLATZs were located nuclei, consistent with predicted role TFs. none was found to have intrinsic activation properties yeast. Our recent work shows FL3 (ZmPLATZ12) interacts RPC53 TFC1, two critical RNA polymerase III...
Deep-sowing is an effective measure to ensure seeds absorbing water from deep soil layer and emerging normally in arid semiarid regions. However, existing varieties demonstrate poor germination ability some key quantitative trait loci (QTL) or genes related deep-sowing remain be identified analyzed. In this study, a high-resolution genetic map based on 280 lines of the intermated B73×Mo17 (IBM) Syn10 doubled haploid (DH) population which comprised 6618 bin markers was used for QTL analysis...
Cell number is a critical factor that determines kernel size in maize (
Kernel weight is a critical factor that essentially affects maize (Zea mays) yield. In natural inbred lines, popcorn kernels exhibit overtly smaller sizes compared to dent corn kernels, and kernel weight, which controlled by multiple genetic loci, varies widely. Here, we characterized major quantitative trait locus on chromosome 1, responsible for controlling (qKW1) size. The qKW1 encodes protein containing seven in absentia domain with E3 ubiquitin ligase activity, expressed prominently...
Abstract Soil salinization is increasingly recognized as a critical environmental challenge that significantly threatens plant survival and agricultural productivity. To elucidate the mechanism of salt resistance in poplar，physiological transcriptomic analysis were conducted on 84 K poplar (Populus alba × P. glandulosa) under varying concentrations (0, 100, 200, 300 mM NaCl). As levels increased, observable damage to progressively intensified. Differentially expressed genes (DEGs) stress...
Cu and Zn are common potentially harmful heavy metals to plants, animals humans. Herein, we investigated the effects of stress on photosynthesis tolerance mechanism alfalfa plants ROS using fluorescence biochemical methods. The results showed that significantly reduced chlorophyll content leaves, while only Chl a content. Fv/Fm decreased under but was not affected by treatment. However, PIABS leaves were sensitive stress. Both resulted in weakening ability PQ library accept electrons, damage...
We examined the effects of Cd and Zn exposure on photosynthetic function tolerant mechanisms ROS metabolism in tobacco leaves. The results showed that photosynthesis inhibition caused by was due to limitation both stomatal non-stomatal factors, while only a significant effect Gs increased generation rate O2•– content H2O2, but did not lead burst. enhanced POD activity, inhibited SOD CAT activities. activities significantly under exposure. activity expression APX. up regulation GPX, GR GST...
Embryo and endosperm originate from the double fertilization, but they have different developmental fates biological functions. We identified a previously undescribed maize seed mutant, wherein embryo appears to be more severely affected than (embryo-specific, emb). In W22 background, emb arrests at transition stage whereas its nearly normal in size. At maturity, W22-emb is apparently small or even invisible. contrast, develops into relative cloned mutant gene on Chromosome 7L designated it...
Nitrogen dioxide (NO2) is recognized as a toxic gaseous air pollutant. However, atmospheric NO2 can be absorbed by plant leaves and subsequently participate in nitrogen metabolism. The metabolism of utilizes consumes the light energy that absorb. As such, it remains unclear whether consumption photosynthetic through decrease capacity or not. In this study, we fumigated mulberry (Morus alba L.) plants with 4 μL·L−1 analyzed distribution using gas exchange chlorophyll fluorescence technology,...
