Vegetable oil's importance extends beyond human consumption to diverse industrial usages. The substantial rise in vegetable oil consumption compels the search for practical methods to enhance plant oil yields. The key genes responsible for the creation of maize grain oil biosynthesis remain largely uncharacterized. Utilizing oil content analysis, bulked segregant RNA sequencing, and mapping, the study determined that su1 and sh2-R genes are implicated in the reduction of ultra-high-oil maize kernel size and the increase in kernel oil content. KASP markers, functionally designed for the su1 and sh2-R genes, uncovered su1su1Sh2Sh2, Su1Su1sh2sh2, and su1su1sh2sh2 mutant phenotypes in a study of 183 sweet maize inbred lines. RNA-Seq data comparing two conventional sweet maize lines to two ultra-high-oil maize lines highlighted significant gene expression variations directly linked to linoleic acid, cyanoamino acid, glutathione, alanine, aspartate, glutamate, and nitrogen metabolism. Through BSA-seq analysis, a further 88 genomic intervals were discovered to be linked to grain oil content, 16 of which overlapped with previously reported maize grain oil QTLs. A combined examination of BSA-seq and RNA-seq information yielded candidate genes. The KASP markers of GRMZM2G176998 (putative WD40-like beta propeller repeat family protein), GRMZM2G021339 (homeobox-transcription factor 115), and GRMZM2G167438 (3-ketoacyl-CoA synthase) exhibited a noteworthy association with the quantity of oil in maize kernels. The final step of triacylglycerol synthesis was catalyzed by GRMZM2G099802 (a GDSL-like lipase/acylhydrolase), which demonstrated significantly greater expression in ultra-high-oil compared to conventional sweet maize lines. The genetic basis for the heightened oil production in ultra-high-oil maize lines, where grain oil contents exceed 20%, will be better understood through these significant findings. The KASP markers developed in this research hold the prospect of influencing the breeding of high-oil sweet corn varieties.
Cultivars of Rosa chinensis, known for their fragrant volatile oils, are essential to the perfume industry. Four rose cultivars, boasting a wealth of volatile substances, were introduced to Guizhou province. Using headspace-solid phase microextraction (HS-SPME) for extraction and two-dimensional gas chromatography quadrupole time-of-flight mass spectrometry (GC GC-QTOFMS) for analysis, volatiles from four Rosa chinensis cultivars were studied in this research project. The identification process revealed 122 different volatile substances; the dominant compounds in these specimens were benzyl alcohol, phenylethyl alcohol, citronellol, beta-myrcene, and limonene. Analysis of Rosa 'Blue River' (RBR), Rosa 'Crimson Glory' (RCG), Rosa 'Pink Panther' (RPP), and Rosa 'Funkuhr' (RF) samples revealed a respective count of 68, 78, 71, and 56 volatile compounds. The volatile contents demonstrated a descending order of concentration, with RBR being the highest, followed by RCG, then RPP, and lastly RF. Similar volatility characteristics were observed in four cultivated types, featuring alcohols, alkanes, and esters as prominent chemical groups, followed by aldehydes, aromatic hydrocarbons, ketones, benzene, and additional compounds. The chemical groups of alcohols and aldehydes were the most prolific, both in terms of the sheer number of compounds present and their percentage concentration. Different cultivars exhibit different aromatic profiles; the RCG cultivar prominently displayed high concentrations of phenyl acetate, rose oxide, trans-rose oxide, phenylethyl alcohol, and 13,5-trimethoxybenzene, indicative of a strong floral and rose-like aroma. RBR was rich in phenylethyl alcohol, and RF held a considerable quantity of 3,5-dimethoxytoluene. Employing hierarchical cluster analysis (HCA) on volatile compounds, three cultivars (RCG, RPP, and RF) displayed analogous volatile profiles compared to each other, contrasted significantly by the RBR cultivar. The biosynthesis of secondary metabolites displays the most distinctive metabolic profile.
Zinc (Zn) is an essential element for the healthy development of plants. A significant percentage of the inorganic zinc incorporated into the soil undergoes a change into an insoluble compound. The transformation of insoluble zinc into plant-available forms by zinc-solubilizing bacteria makes them a valuable alternative to supplementing zinc. The objective of this research was to explore the potential of native bacterial strains to solubilize zinc and assess their effect on wheat growth and zinc biofortification. At the National Agriculture Research Center (NARC) in Islamabad, Pakistan, a multitude of experiments were performed throughout the 2020-2021 period. Plate assays were used to evaluate the zinc-solubilizing activity of a collection of 69 strains, employing zinc oxide and zinc carbonate as insoluble zinc sources. A crucial part of the qualitative assay was the measurement of solubilization index and solubilization efficiency. To determine the quantitative Zn and phosphorus (P) solubility, the qualitatively identified zinc-solubilizing bacterial strains were further tested using a broth culture method. The experiment used tricalcium phosphate as a non-soluble phosphorus source. The results showed a negative correlation between the pH of the broth and the dissolution of zinc, particularly for ZnO (r² = 0.88) and ZnCO₃ (r² = 0.96). immediate recall Pantoea species, among ten novel promising strains, are noteworthy. A Klebsiella sp., strain NCCP-525, was observed and confirmed. Brevibacterium sp. designated as NCCP-607. NCCP-622, a Klebsiella species, is the subject of this report. In the study of bacterial strains, Acinetobacter sp. NCCP-623 was selected. NCCP-644, a strain of Alcaligenes sp. Of the Citrobacter species, NCCP-650 is a representative strain. The species Exiguobacterium sp., identified as NCCP-668. The strain NCCP-673, belonging to the Raoultella species. NCCP-675 and Acinetobacter sp. were observed. Strains NCCP-680, sourced from the Pakistani ecology and showcasing plant growth-promoting rhizobacteria (PGPR) characteristics, including the solubilization of Zn and P, in addition to positive nifH and acdS genes, were chosen for enhanced wheat crop experimentation. A control study was performed to ascertain the threshold zinc level affecting wheat growth before evaluating the efficacy of bacterial strains. Two wheat types (Wadaan-17 and Zincol-16) were exposed to diverse zinc concentrations (0.01%, 0.005%, 0.001%, 0.0005%, and 0.0001% from ZnO) in a sand culture within a glasshouse environment. The irrigation of wheat plants employed a zinc-free Hoagland nutrient solution. Therefore, the most significant critical level for wheat's growth was found to be 50 mg kg-1 of Zn from ZnO. Selected zinc-solubilizing bacterial strains (ZSBs) were inoculated onto wheat seeds, in either a solo or a collective manner, alongside or devoid of zinc oxide (ZnO), within a sterilized sand culture, at a critical zinc level of 50 mg kg⁻¹. ZSB inoculation in a ZnO-free consortium improved shoot length by 14%, shoot fresh weight by 34%, and shoot dry weight by 37%, as compared to the control. Introducing ZnO, however, caused a 116% enhancement in root length, a 435% rise in root fresh weight, a 435% upswing in root dry weight, and a 1177% escalation in shoot Zn content, measured against the control. Wadaan-17 exhibited superior growth compared to Zincol-16, though Zincol-16's shoot zinc concentration was 5% greater. Lung microbiome This investigation determined that the tested bacterial strains possess the capacity to act as ZSBs and are highly efficient bio-inoculants for addressing zinc deficiency in wheat. In a consortium, these strains performed better in promoting growth and zinc solubility compared to individual inoculation. The study's conclusion further stated that a zinc oxide dose of 50 mg kg⁻¹ had no detrimental effect on the growth of wheat; however, greater concentrations were detrimental to wheat's growth.
