Membrane-Bound Transcriptional Activator NTL1 from Rapeseed Positively Modulates Leaf Senescence through Targeting Genes Involved in Reactive Oxygen Species Production and Programmed Cell Death.

J Agric Food Chem 2021 Apr 20. Epub 2021 Apr 20.

State Key Laboratory of Crop Stress Biology for Arid Areas and, College of Life Sciences, Northwest A & F University, Yangling, Shaanxi 712100, China.

Leaf senescence is the last stage of leaf development and is determined by various environmental and endogenous signals. Leaf senescence can determine plant productivity and fitness. Transcription factors (TFs) with the transmembrane domain constitute a special group of regulatory proteins that can translocate from the membrane system into nuclei to exert the transcriptional function upon endogenous or exogenous stimuli.

Chlorophyll breakdown in senescent cotyledons of rape, Brassica napus L.: Enzymatic cleavage of phaeophorbide a in vitro.

New Phytol 1995 Feb;129(2):237-246

Institut für Pflanzenbiologie, Universität Zürich, Zollikerstrasse 107, CH-8008 Zürich, Switzerland.

Solubilization of senescent thylakoids from rape cotyledons in the presence of Triton X-100 was employed to establish an in vitro system that allowed the assessment of enzymatic conversion of phaeophorbide a into an uncoloured fluorescent chlorophyll catabolite, Bn-FCC-2. The action of the putative dioxygenase responsible for the cleavage of the porphyrin macrocycle depends on reduced ferredoxin as reductant. Apart from this thylakoidal catalyst, stromal protein is also required for the production of FCC-2 in vitro. Read More

Individual Rather Than Simultaneous Priming with Glutathione and Putrescine Reduces Chromium Cr Toxicity in Contrasting Canola (Brassica napus L.) Cultivars.

Bull Environ Contam Toxicol 2021 Apr 10. Epub 2021 Apr 10.

Institute of Molecular Biology and Biotechnology, The University of Lahore, Lahore, Pakistan.

The chromium (Cr) toxicity mechanisms have not been fully revealed yet in plants mainly due to its complex electronic chemistry. Both putrescine (PUT) and glutathione (GSH) are reported to be involved in plethora of plant cellular processes. Therefore, we hypothesized that exogenous individual or co-application of PUT and GSH could alleviate the Cr stress in genetically diverse canola cultivars. Read More

Drought Intensity-Responsive Salicylic Acid and Abscisic Acid Crosstalk with the Sugar Signaling and Metabolic Pathway in .

Plants (Basel) 2021 Mar 23;10(3). Epub 2021 Mar 23.

Department of Animal Science, Institute of Agricultural Science and Technology, College of Agriculture & Life Science, Chonnam National University, Gwangju 61186, Korea.

The aim of this study was to characterize hormonal crosstalk with the sugar signaling and metabolic pathway based on a time course analysis of drought intensity. Drought intensity-responsive changes in the assimilation of newly fixed carbon (C) into soluble sugar, the content of sugar and starch, and expression of genes involved in carbohydrate metabolism were interpreted as being linked to endogenous abscisic acid (ABA) and salicylic acid (SA) levels and their signaling genes. The ABA and SA levels in the drought-stressed leaves increased together during the early drought period (days 0-6), and additional ABA accumulation occurred with depressed SA during the late period (days 6-14).

Acylation of nonspecific phospholipase C4 determines its function in plant response to phosphate deficiency.

Plant J 2021 Apr 1. Epub 2021 Apr 1.

National Key Laboratory of Crop Genetic Improvement, Huazhong Agricultural University, Wuhan, 430070, China.

Nonspecific phospholipase C (NPC) is involved in plant growth, development and stress responses. To elucidate the mechanism by which NPCs mediate cellular functions, here we show that NPC4 is S-acylated at the C-terminus and the acylation determines its plasma membrane (PM) association and function. The acylation of NPC4 was detected using NPC4 isolated from Arabidopsis and reconstituted in vitro. Read More

Genome-wide analysis of long noncoding RNAs, 24-nt siRNAs, DNA methylation and H3K27me3 marks in Brassica rapa.

PLoS One 2021 31;16(3):e0242530. Epub 2021 Mar 31.

Institute of Scientific and Industrial Research, Osaka University, Mihogaoka, Ibaraki-city, Osaka, Japan.

Long noncoding RNAs (lncRNAs) are RNA fragments that generally do not code for a protein but are involved in epigenetic gene regulation. In this study, lncRNAs of Brassica rapa were classified into long intergenic noncoding RNAs, natural antisense RNAs, and intronic noncoding RNAs and their expression analyzed in relation to genome-wide 24-nt small interfering RNAs (siRNAs), DNA methylation, and histone H3 lysine 27 trimethylation marks (H3K27me3). More than 65% of the lncRNAs analyzed consisted of one exon, and more than 55% overlapped with inverted repeat regions (IRRs). Read More

Expression of a Bacterial Trehalose-6-phosphate Synthase otsA Increases Oil Accumulation in Plant Seeds and Vegetative Tissues.

Front Plant Sci 2021 10;12:656962. Epub 2021 Mar 10.

Department of Biology, Brookhaven National Laboratory, Upton, NY, United States.

We previously demonstrated that exogenous trehalose 6-phosphate (T6P) treatment stabilized WRINKLED1 (WRI1), a master transcriptional regulator of fatty acid (FA) synthesis and increased total FA content in () embryo suspension cell culture. Here, we explore lines heterologously expressing the T6P synthase (otsA) or T6P phosphatase (otsB) to refine our understanding regarding the role of T6P in regulating fatty acid synthesis both in seeds and vegetative tissues. 35S: transgenic seeds showed an increase of 13% in fatty acid content compared to those of wild type (WT), while seeds of 35: transgenic seeds showed a reduction of 12% in fatty acid content compared to WT.

L2,1-norm regularized multivariate regression model with applications to genomic prediction.

Bioinformatics 2021 Mar 28. Epub 2021 Mar 28.

Systems Biology and Mathematical Modeling Group, Max Planck Institute of Molecular Plant Physiology, Am Mühlenberg 1, 14476 Potsdam-Golm, Germany.

Motivation: Genomic selection (GS) is currently deemed the most effective approach to speed up breeding of agricultural varieties. It has been recognized that consideration of multiple traits in GS can improve accuracy of prediction for traits of low heritability. However, since GS forgoes statistical testing with the idea of improving predictions, it does not facilitate mechanistic understanding of the contribution of particular single nucleotide polymorphisms (SNP).

Mitigation of yield-scaled nitrous oxide emissions and global warming potential in an oilseed rape crop through N source management.

J Environ Manage 2021 Mar 24;288:112304. Epub 2021 Mar 24.

Departamento de Química y Tecnología de Alimentos, ETSI Agronómica, Alimentaria y de Biosistemas, Universidad Politécnica de Madrid (UPM), Madrid, Spain; Centro de Estudios e Investigación para la Gestión de Riesgos Agrarios y Medioambientales (CEIGRAM), Universidad Politécnica de Madrid (UPM), Madrid, Spain.

Enhanced-efficiency nitrogen (N) fertilizers, such as those containing nitrification or urease inhibitors, can mitigate the carbon (C) footprint linked to the production of bioenergy crops through a reduction in direct nitrous oxide (NO) emissions and indirect NO losses. These indirect emissions are derived from ammonia (NH) volatilization, which also have important environmental and health implications. The evaluation of the global warming potential (GWP) of different N sources using site-specific data of yield and direct and indirect emissions is needed for oilseed rape under rainfed semi-arid conditions, especially when meteorological variability is taken into account.
