The increase in crop productivity is an urgent need of the time to reduce scarcity of food in underdeveloped countries. Several biological, chemical and physical methods have been applied to promote crop yield. Application of magnetic field (MF) is an emerging physical method used to increase plant growth and yield. The reports on MF pretreatment-induced nutritional changes in harvested seeds are scarce. We previously identified the optimal frequency of MF to improve plant growth and yield as 1500 nT at 10...

The study on Stevia callus has the potential to advance the knowledge of antioxidant mechanisms involved in unorganized cells response to drought stress. The effects of polyethylene glycol (PEG; 0 and 4% w/v) in combination with paclobutrazol (PBZ; 0 and 2 mg l-1 ) and gibberellin (GA; 0 and 2 mg l-1 ) were studied on Stevia rebaudiana callus. PEG treatment led to an oxidative stress, as indicated by increased H2 O2 content whose accumulation was prevented with PBZ and GA treatments. All treatments of PEG, PBZ and GA increased the total antioxidant capacity, with the highest antioxidant power in PBZ and GA treatments without PEG...

Paulownia is a tree native to China, with important ecological and economic value. Long noncoding RNAs (lncRNAs) are known to play important roles in eukaryotic gene regulation. However, no lncRNAs have been reported in Paulownia so far. We performed RNA sequencing of two Paulownia tomentosa lncRNA libraries constructed from the terminal buds of normal untreated seedlings and 60 mg L-1 MMS-treated seedlings, and obtained a total of 2531 putative lncRNAs. The average length of the lncRNA transcripts was much less than the average length of the mRNA transcripts in the P...

Cyanobacteria are one of the ancient bacterial species occupying a variety of habitats with diverse metabolic preferences. RNA regulators like riboswitches play significant role in controlling the gene expression in prokaryotes. The taxonomic distribution of riboswitches suggests that they might be one of the oldest mechanisms of gene control system. In this paper, we analyzed the distribution of different riboswitch families in various cyanobacterial genomes. It was observed that only four riboswitch classes were abundant in cyanobacteria, B12 -element (Cob)/AdoCbl/AdoCbl-variant riboswitch being the most abundant...

Efficient protocols for somatic embryogenesis of papaya ( Carica papaya L.) have great potential for selecting elite hybrid genotypes. Addition of polyethylene glycol (PEG), a nonplasmolyzing osmotic agent, to a maturation medium increases the production of somatic embryos in C . papaya . To study the effects of PEG on somatic embryogenesis of C . papaya , we analyzed somatic embryo development and carbohydrate profile changes during maturation treatments with PEG (6%) or without PEG (control). PEG treatment (6%) increased the number of normal mature somatic embryos followed by somatic plantlet production...

We started a cell suspension culture from magenta coloured calli of cockscomb to study the effect of biotic and abiotic elicitors on the biosynthesis of betalain pigments. The cultures were grown in a flask containing 30 ml MS media fortified with 13.5 μM 2,4-D and 0.44 μM BAP. These cultures were elicited during its log-phase of growth using fungal elicitors (prepared from mycelia of Fusarium oxysporum) , yeast extract, copper sulphate and cobalt chloride. The elicitation reduced the cell count, cell viability and percent pigmented cell in the suspension culture...

20-Hydroxyecdysone is one of the most common ecdysteroids in plants with potential therapeutic applications. In this study, cell suspension cultures of Achyranthes aspera were raised in shake flasks to investigate the production of 20-hydroxyecdysone. The quantification and characterization of 20-hydroxyecdysone in the cultures were done by High performance liquid chromatography (HPLC) and Liquid Chromatography-quadrupole time-of- flight mass spectrometry (LC-Q-TOF) analyses. For raising the suspension, calli initiated from in vitro grown leaf explants were cultured in liquid Murashige and Skoog (MS) medium augmented with combinations of 2, 4-dichlorophenoxyacetic acid (1 mg L-1 ) and α-naphthaleneacetic acid (1 mg L-1 )...

Unbranched heterocytous cyanobacteria produce a number of serine peptidases. We have characterized several peptidases in the cell-free extracts of a true-branched N2 -fixing cyanobacterium, Westiellopsis ramosa sp. nov. Upon substrate-gel zymography of intact filaments and heterocytes, five peptidase bands were resolved, whereas in vegetative cells, a single band was discernible. No band was detected in [Formula: see text]-grown cultures suggesting that the peptidases were present under diazotrophic conditions with much of them confined to heterocytes...

Salt stress impedes the productivity of wheat ( Triticum aestivum L.) in many parts of the world. This study evaluated the potential role of benzyl aminopurine (BAP) and sorghum water extract (SWE) in improving the wheat performance under saline conditions. Seeds were primed with BAP (5 mg L-1 ), SWE (5% v/v), BAP + SWE, and distilled water (hydropriming). Soil filled pots maintained at the soil salinity levels of 4 and 10 dS m-1 were used for the sowing of primed and non-primed seeds. Salt stress suppressed the wheat growth; seed priming treatments significantly improved the wheat growth under optimal and suboptimal conditions...

Adverse environmental conditions limit various aspects of plant growth, productivity, and ecological distribution. To get more insights into the signaling pathways under low temperature, we identified 10 C-repeat binding factors ( CBFs ), 9 inducer of CBF expression ( ICEs ) and 10 cold-responsive ( CORs ) genes from Aegilops - Triticum composite group under cold stress. Conserved amino acids analysis revealed that all CBF, ICE, COR contained specific and typical functional domains. Phylogenetic analysis of CBF proteins from Triticeae showed that these CBF homologs were divided into 11 groups...
