The roles of proteinases and proteinase inhibitors in plant-nematode interactions
… the first part of this study, tomato and tobacco root cultures and seedlings aseptically grown in agar medium were developed to test the roles of proteinase inhibitor transgenes in enhancing plant resistance against nematodes. Root galling in cultured root and seedlings expressing inhibitor I or …

De novo Sequencing and Analysis of <em>Salvia hispanica</em> Transcriptome and Identification of Genes Involved in the Biosynthesis of Secondary Metabolites
… bp paired-end sequences from the chia leaf and root tissues. The sequences were de novo assembled into 103,367 contigs with average length of 1,445 bp. The resulted assembly represented 92.2% transcriptome completeness. Around 69% of the assembled contigs were annotated against the uniprot …

Investigating Root Storage and Exudation in the Brachypodium Genus
In plants, sources are the tissues where a specific nutrient is absorbed or fixed into a plant, and sinks are the tissues in the plant where the nutrients are dispersed after they are absorbed or fixed. In the case of carbon, leaves tend to be the source, as most photosynthesis occurs in the …

Vanadium uptake and transport in higher plants
… been examined. Studies utilizing excised Hordeum roots have revealed the uptake patterns of two different ionic species of vanadium (V02+ and V03) to be similar. Both ionic forms exhibited a large extracellular component in their uptake. This extracellular component was shown to be exchangeable …

Nitrate reductase in apple trees
… to optimize the assay conditions for various tissues of MM 106 apple trees. Optimum concentrations of nitrate and phosphate for in vivo nitrate reductase activities ranged from 50 to 100 mM and were tissue-specific. The optimum pH of the assay medium was 7.5. Vacuum infiltration and the …

Tolerance to barley yellow dwarf viruses in two pairs of sister oat lines
… and accumulates to similar levels in shoot and root tissues of these lines. RPV-IL titers were higher in the susceptible line than in tolerant lines.

Studies on lignin biosynthesis and structure
… and subsequent isolation of the lignin from the root tissue as its acetal derivative demonstrated the incorporation of the labelled feru1ic acid into the lignin component of the tissue. Through sim1lar administrations of (1-¹³C, 2-¹³C and 3-¹³C) ferul1c acid and subsequent analysis of the root …

Understanding the mechanism of salt tolerance in alfalfa (Medicago sativa L.)
… of organic compounds and elements in different tissues of the two alfalfa cultivars under five different salinity stresses, and 3) to identify differentially expressed gene(s) in leaf and root tissues at 12 dS m-1. The response of the alfalfa cultivars to salinity was studied for 12 weeks in …

Transcriptional and Post-Transcriptional Regulation of Nodule-Specific Gene Expression in Soybean
<p>Lateral roots and nodules are two important nutrient acquisition organs in soybean. The evolutionary origin of nodules from lateral roots has been highly hypothesized based on morphological similarities and genetic studies, but gene expression profiles during the formation of these organs have …

<i>In Planta</i> "Green Engineering" of Variable Sizes and Exotic Shapes of Gold Nanoparticles: An Integrative Eco-Friendly Approach
… plant species in accumulating gold in the root tissues ranging from 500 ppm (ryegrass) to 2500 ppm (alfalfa). Sunflower and oregano translocated significantly higher levels of gold into their aerial tissues compared to other species. This study thus suggested differential abilities of …

Phosphorus nutrition of Ilex crenata 'Helleri' grown in a pine bark medium
… pine bark P level increased to 10 ppm P, while root dry weight decreased with increasing pine bark P levels. Total mg of P in shoot tissues continued to increase with P treatments higher than 10 ppm, indicating luxury consumption of P. Total mg of P in root tissues increased to the 10 ppm P …

Plant Functional Traits and Ecosystem Functions in Experimental Grassland Stands
… compounds in nutrient solution cultures. III The Root Mineralisation Experiment (RME) aimed at evaluating potential implications of the identity of rhizosphere microflora on mineralisation performance of root tissues from H. lanatus and R. acris derived from RDE. Root biomass for the RME was …

Analysis of the Expression Profiles of Two Isoforms of the Antifungal Protein Osmotin from Gossypium hirsutum
… osmotin mRNAs are expressed constitutively in root tissues of cotton plants, and that they are rapidly induced in leaf and stem tissues upon ethylene treatment. Real time RT-PCR indicated that osmotin transcript levels were induced 2 to 4 h after treatment with ethephon. The osmotin mRNA levels …

New signalling network in plant abiotic stress discovered through a genetic approach
… regulation of the transgene in shoot and root organs, has been observed in one of the studied mutants, after salt and ABA treatments. And third, an enhanced expression of the RCI2A::luc transgene in root tissues after ethylene treatment, indicates the involvement of the phytohormone in the …

A cytochemical and biochemical study of acid hydrolases in developing plant cells, with particular reference to non-specific esterases
… naphthol AS BI phosphatase in dividing unfixed root cells of Vicia f aba do not act as a 'trigger 1 in the way suggested for animal cells, since there were significantly greater numbers of particles in mitotic cells as opposed to interphase cells in all 3 root tissues, apical initials, procortex …

Investigating the role of phytohormones during desiccation in two evolutionarily distinct resurrection plants
… plants, but also within their leaf and root tissues. ABA emerged as a central regulator of stress responses, while jasmonic acid (JA) appeared to play more of a supporting role, and the dynamics of OPDA, a precursor of JA, suggested a potential alternative signalling pathway that may …

Genome editing for engineering resilience to climate changes in grapevine
… evaluating sporangia density in inoculated leaf tissues, no significant differences were observed among genotypes in three different experiments. Our observation conducted on leaf discs explants suggest that stomatal density may not play a major role in controlling and limiting Plasmopara …
