related genes. It serves as a modern molecular tool to knockdown the expression of genes and manipulates mammalian cells through RNAi. By utilizing this unparallel power of RNAi, the scientists are trying to achieve large scale functional manipulations. In mammalian cells virus derived small RNA (vs-RNA) has been detected in 1 variety of human cell...

Fagonia indica is one of the commercially vital medicinal plant species. It is well-known for biosynthesis of anticancer phenolics and flavonoids metabolites. The plant has been exploited for in vitro studies and production of vital phytochemicals, however, the synergistic effects of melatonin and lights remains to be investigated. In current study...

Gonorrheal infections are the second most prevalent sexually transmitted diseases STDs in the USA populations after Chlamydia. These infections have now become an urgent problem to address because Neisseria gonorrhoeae is capable of developing resistance to multiple antibiotic classes. Infection with these antibiotic-resistant strains has become th...

Lepidium sativum L. is a rich source of polyphenols that have huge medicinal and pharmaceutical applications. In the current study, an effective abiotic elicitation strategy was designed for enhanced biosynthesis of polyphenols in callus culture of L. sativum. Callus was exposed to UV-C radiations for different time intervals and various concentrat...

Lepidium sativum L. is an important edible, herbaceous plant with huge medicinal value as cardio-protective, hepatoprotective and antitumor agent. This study was designed and performed to investigate biosynthesis of plant's active ingredients in callus cultures of L. sativum in response to the exposure of multi spectral lights. Optimum biomass accu...

Optimum fruit quality is crucial for export. For ‘Calypso™’ mango fruit, vapour heat treatment (VHT) is an important postharvest measure for fruit fly control. However, this phytosanitary treatment has been associated with expression of physiological disorders in the fruit. Among other determinants, fruit robustness and postharvest quality is linke...

Ajuga integrifolia Buch. Ham. ex D.Don (Family: Lamiaceae) is a wild crafted perennial medicinal herb. Ajuga integrifolia rapid micro-propagation was induced to get disease-free plantlets and high yield agitated micro-shoot cultures by in vitro shoot culture. Micro-shoots were supplemented with Chitosan (CHT) and Melatonin (MEL) in a dose-dependent...

‘Calypso™’ mango was developed in Australia and is an important export cultivar. However, it can express internal disorders (IDs) after postharvest vapour heat treatment (VHT), a prerequisite phytosanitary protocol for export. IDs negatively influence consumer satisfaction, including repeat purchase. The incidence and severity of fruit disorders ar...

In the context of a value chain, producing high-quality avocado fruit that can pass through the stages of harvest, treatment, handling, and marketing in fresh produce supply chains is pivotal to meeting and ideally exceeding retailer and consumer expectations. This is particularly important to establishing, maintaining, and growing markets. This is...

Moringa oleifera, also called miracle tree, is a pharmaceutically important plant with a multitude of nutritional, medicinal, and therapeutic attributes. In the current study, an in-vitro-based elicitation approach was used to enhance the commercially viable bioactive compounds in an in vitro callus culture of M. oleifera. The callus culture was es...

Ajuga integrifolia Buch. Ham. ex D.Don, a member of Lamiaceae family is pharmaceutically an active perennial herb widely spread in China, Afghanistan and Pakistan Himalayan region. The application of biotic elicitors is a promising approach to cover limitations of in vitro cell technology and challenges faced by pharmaceuticals industry for bulk up...

In vitro cultures of scarlet flax (Linum grandiflorum L.), an important ornamental flax, have been established as a new possible valuable resource of lignans and neolignans for antioxidant and anti-inflammatory applications. The callogenic potential at different concentrations of α-naphthalene acetic acid (NAA) and thidiazuron (TDZ), alone or in co...

Nanotechnology is a promising field and has diverse applications. Primarily, nanoparticles have been synthesized via chemical and physical methods. Dyes are synthetic organic compounds that are abundantly used in industries especially in textile industry. The use of these dyes is major contributors towards environmental pollution. Their hazardous n...

Ocimum basilicum L. var purpurascens (purple basil) contains medicinally valuable metabolites. Light greatly influences the physiological processes, including biomass accumulation and secondary metabolites production in medicinal plants. Herein, we investigated the influence of different spectral lights on the biosynthesis of phenylpropanoid metabo...

Eclipta alba L., also known as false daisy, is well known and commercially attractive plant with excellent hepatotoxic and antidiabetic activities. Light is considered a key modulator in plant morphogenesis and survival by regulating important physiological cascades. Current study was carried out to investigate growth and developmental aspects of E...

Solanum xanthocarpum is considered an important traditional medicinal herb because of its unique antioxidant, and anti-diabetic, anti-aging, and anti-inflammatory potential. Because of the over exploitation linked to its medicinal properties as well as destruction of its natural habitat, S. xanthocarpum is now becoming endangered and its supply is...

Abstract Ajuga integrifolia Buch. Ham. ex D.Don is pharmacologically important plant, commonly known as Kori Booti. Phytochemicals of this plant are used to treat variety of illnesses, ranging from mild tooth ache to malaria and inflammatory diseases. In present study, exogenous role of plant signaling molecules such as salicylic acid (SA) and gib...

The present study evaluated interactive effect of melatonin and UV-C on phenylpropanoid metabolites profile and antioxidant potential of Ocimum basilicum L. Callus was treated with varying concentrations of melatonin and UV-C radiations for different time duration, either alone and/or in combination. Individual treatments of both UV-C and melatonin...

Silybum marianum (L.) Gaertn. is a well-known medicinal herb, primarily used in liver protection.
