Gibberellins (GAs) are tetracyclic diterpenoids that essential endogenous regulators of plant growth and development. GA levels within the regulated by a homeostatic mechanism includes changes in expression family GA-inactivating enzymes known as 2-oxidases. Ectopic pea 2-oxidase2 cDNA caused seed abortion Arabidopsis, extending confirming previous observations obtained with GA-deficient mutants pea, suggesting GAs have an role A new physiological for pollen tube vivo also has been...

Salicylic acid (SA), a natural defensive signal chemical, and antimycin A, cytochrome pathway inhibitor, induce resistance to Tobacco mosaic virus (TMV). Pharmacological evidence suggested signaling during induction by both chemicals involved alternative oxidase (AOX), sole component of the respiratory (AP). Roles AP include regulation intramitochondrial reactive oxygen species maintenance metabolic homeostasis. Transgenic tobacco (Nicotiana tabacum) with modified capacities (2- 3-fold...

Ferrochelatase catalyzes the insertion of Fe²⁺ into protoporphyrin IX to generate protoheme. In higher plants, there is evidence for two isoforms this enzyme that fulfill different roles. Here, we describe isolation a second ferrochelatase cDNA from cucumber (<i>CsFeC2</i>) was less similar previously isolated isoform (<i>CsFeC1</i>) than it some ferrochelatases other plants. In<i>in vitro</i> import experiments, showed characteristics their respective counterparts <i>Arabidopsis...

The production of commercially important rare-earth elements in significant proportions also leads to the problem industrial effluents containing metal oxides, cyanides, etc. generated from mining, mineral processing, and metallurgical operations. In current work, ultrasound (US)-based methods are used for treatment obtained effluent processing industry ammonium thiocyanate (NH4SCN) as a major target contaminant. effect operating parameters pH (actual values 1, 3, 7, 9, 12), H2O2 loading...

We have examined the role of gibberellins (GAs) in plant development by expression pea GA 2-oxidase2 (PsGA2ox2) cDNA, which encodes a inactivating enzyme, under control MEDEA (MEA) promoter. Expression MEA:PsGA2ox2 Arabidopsis caused seed abortion, demonstrating that active GAs endosperm are essential for normal development. plants had reduced ovule number per ovary and exhibited defects phyllotaxy leaf morphology were partly suppressed treatment. The architecture also restored sly1-d...

Abstract Ectopic expression in Arabidopsis of a pea (Pisum sativum) cDNA (2ox2) encoding gibberellin (GA) 2-oxidase (PsGA2ox2), involved the deactivation biologically active GAs, has been used to establish role for GAs promoting pollen tube growth. One line, 35S:2ox2/28c, when homozygous transgene, exhibits novel small fruit phenotype. The 28c transgene reduces growth, and this results reduced number fertilized seeds that are only present at end silique nearest stigma. To confirm phenotype...

Plant cell wall structure integrity and associated tissue mechanical properties is one of key determinants for the perceived texture plant-based foods. Carrots (Daucus carota) were used to investigate effect mineral supply boron (B) and/or calcium (Ca), during plant growth, on matured root tissues. Five commercial cultivars carrots, Kuroda (orange), Dragon Purple, Kuttiger White, Yellow, Nutri-Red, cultivated under controlled glasshouse conditions over two seasons. Significant increases in...

Polyphenol oxidase (PPO) mimics have advantage of detection and remediation polyphenols. This work demonstrates rapid sensitive colorimetric phenolic compounds using nanocomposite magnesium ferrite (MgFe2O4) manganese oxide (Mn3O4) nanoparticles as PPO mimic. The catalytic properties MgFe2O4 Mn3O4 displayed synergistic effect in the nanocomposite. synthesized were fully characterized various analytical techniques. ratio was optimized. Catechol resorcinol taken model best PPO-activity shown...

A Field investigation was carried out to study the effects of organic (FYM) and inorganic nitrogen alone or in combination with bio-fertilizer consortium (Azotobacter, PSB PGPR) on growth, yield attributes, economics turmeric (Curcuma longa L.) during 2012-13 at Punjab Agricultural University, Ludhiana. The treat-ments were comprised 75, 100 (25 t ha-1 FYM ~ 125 kg N ha-1) per cent recommended control. Results revealed that application manure had beneficial attributes turmeric. maximum 204.4...

A field experiment was conducted for three years to study the effect of sowing dates, mulching and seed rates on nutrient uptake productivity soybean under irrigated conditions in sub-humid Punjab a silty clay loam soil which low available N, medium P K. The split plot design with combination dates mulch main plots sub-plots replications fixed site. results revealed that June 30 recorded highest number pods plant-1.There no significant influence yield attributes. Seed also remained at par...

The present investigation was carried out to characterize the eighty one carrot genotypes through variability, heritability and genetic gain for different characters. Analysis of variance revealed highly significant differences among all Genetic advance were estimated marketable its component yield traits in 81 lines (Daucus carota var. sativa L.). study showed high ranges total (4.9-9.3 kg plot-1), (4.6-9.2 root length (13.8-30.8 cm) weight (101.4-127.2 g). Genotypes PC-161, PC-15, PC-173...

Many factors restrict honey bees? productivity and pollination potential, especially with the infestation of Greater wax moth, Galleria mellonella L., synthetic pesticides used to manage this pest. Therefore, a study was conducted examine efficacy oils extracted from Pongamia pinnata, Mentha piperita, Ocimum basilicum, Thymus vulgaris on biology survival moth. The results revealed that all treatments exhibited control over hatching potential eggs, lowest egg hatchability (6.67%) observed...
