Crop residue incorporation is a common practice to increase or restore organic matter stocks in agricultural soils. However, this often increases emissions of the powerful greenhouse gas nitrous oxide (N2O). Previous meta-analyses have linked various biochemical properties crop residues N2O emissions, but relationships between these been overlooked, hampering our ability predict from specific residues. Here we combine comprehensive databases for and characteristics with random-meta-forest...
Crop residues are important inputs of carbon (C) and nitrogen (N) to soils thus directly indirectly affect nitrous oxide (N2 O) emissions. As the current inventory methodology considers N by crop as sole determining factor for N2 O emissions, it fails consider other underlying factors processes. There is compelling evidence that emissions vary greatly between with different biochemical physical characteristics, concentrations mineralizable decomposable C in residue biomass both enhancing...
Many plant phytochemicals constitute binary enzyme–glucoside systems and function in defence. In brassicas, the enzyme myrosinase is confined to specific myrosin cells that separate from its substrate; glucosinolates. The myrosinase-catalysed release of toxic bioactive compounds such as isothiocyanates, upon activation or tissue damage, has been termed 'the mustard oil bomb' characterized a 'toxic mine' removal triggers have investigated by genetically modifying Brassica napus plants remove...
Abstract An alloplasmic mustard, Brassica juncea , has been synthesized by placing its nucleus into the cytoplasm of related wild species Erucastrum canariense to express cytoplasmic male sterility. To achieve this, sexual hybrid E. (2 n =18, E c ) × campestris = 20, AA) was repeatedly backcrossed B. (2n 36, AABB). Cytoplasmic male‐sterile (CMS) plants were recovered in BC 4 generation. These are a normal green and flowers have slender, non‐dehiscing anthers that contain sterile pollen....
The Brassicaceae family is characterized by a unique defence mechanism known as the 'glucosinolate–myrosinase' system. When insect herbivores attack plant tissues, glucosinolates are hydrolysed enzyme myrosinase (EC 3.2.1.147) into variety of degradation products, which can deter further herbivory. This process has been described 'the mustard oil bomb'. Additionally, damage induces production glucosinolates, myrosinase, and other defences. Brassica napus seeds have genetically modified to...
The glucosinolate-myrosinase system is a well-known plant chemical defence system. Two functional myrosinase-encoding genes, THIOGLUCOSIDASE 1 (TGG1) and 2 (TGG2), express in aerial tissues of Arabidopsis. TGG1 expresses guard cells (GCs) also highly abundant protein GCs. Recently, by studying wild type (WT), tgg single, double mutants, we showed novel association between the system, physical barrier, cuticle. In current study, using imaging techniques, further analysed stomata...
Oilseed rape and other crop plants of the family Brassicaceae contain a unique defence system known as glucosinolate–myrosinase or 'mustard oil bomb'. The bomb' which includes myrosinase glucosinolates is triggered by abiotic biotic stress, resulting in formation toxic products such nitriles isothiocyanates. Myrosinase present specialist cells 'myrosin cells' can also be mines. myrosin cell idioblasts Brassica napus were genetically reprogrammed to undergo controlled death (ablation) during...
Abstract Both physical barriers and reactive phytochemicals represent two important components of a plant’s defence system against environmental stress. However, these systems have generally been studied independently. Here, we taken an exclusive opportunity to investigate the connection between chemical-based plant system, represented by glucosinolate-myrosinase barrier, cuticle, using Arabidopsis myrosinase (thioglucosidase; TGG) mutants. The tgg1 , single tgg2 double mutants showed...
In the present investigation, laboratory trials were conducted to investigate synergistic, additive or antagonistic effect of three sub-lethal dose rates (2 x 10 3 , 4.5 and 6 PIB/Larva) native isolated Nucleopolyhydrovirus (NPV) from Spodoptera litura Spinosad (0.01 ppm) against rd 4 th instar larvae collected different geographical areas Punjab (Pakistan).A difference in larval mortality, pupation, adult emergence egg ecluson was observed.The higher but rate NPV with exhibited synergistic...
Abstract Intergeneric hybrids involving a wild crucifer, Diplotaxis siifolia (2n = 20; D s ), and two crop Brassica species, namely rapa AA) B. juncea 36; AABB), were developed through sequential ovary/ovule culture. Hybridization was successful only when D. used as the female parent, indicating unilateral cross incompatibility. Hybrids intermediate between parents for morphological characteristics but had low male well fertility. Meiotic studies of revealed partial homoeology A/B genomes.
Abstract Fishbones contain significant amounts of plant nutrients. Fish residues may be preserved by acidification to pH < 4, which affect the chemical extractability, and availability nutrients when applied as fertilisers. Grinded bone material from cod ( Gadus morhua ) heads was mixed with formic acid investigate if this would increase concentrations ammonium lactate–acetate (AL)-extractable Two degrees fineness fishbones (coarse 2–4 mm; fine 0.71 mm) were compared at 3.0 4.0 plus a...
