The development of a protocol for the large-scale production of and its variants with little to no somaclonal variation or disease for pharmaceutical and for other industrial use has been an emerging area of research. A limited number of protocols have been developed around the world, obtained through a detailed literature search using web-based database searches, e.g.

Cytokinins (CKs) are a chemically diverse class of plant growth regulators, exhibiting wide-ranging actions on plant growth and development, hence their exploitation in agriculture for crop improvement and management. Their coordinated regulatory effects and cross-talk interactions with other phytohormones and signaling networks are highly sophisticated, eliciting and controlling varied biological processes at the cellular to organismal levels. In this review, we briefly introduce the mode of action and general molecular biological effects of naturally occurring CKs before highlighting the great variability in the response of fruit crops to CK-based innovations.

Article Synopsis
  • The study investigates the impact of smoke-water and karrikinolide on the phytochemicals and antioxidant activity of a declining African plant subspecies, crucial for its medicinal use.
  • The research involved culturing plant leaf explants in nutrient media supplemented with these substances and analyzing the resulting phytochemicals and antioxidant levels using advanced chromatography and chemical tests.
  • Results indicate that both smoke-water and karrikinolide significantly enhance the production of beneficial phytochemicals and their antioxidant activity in the plants, suggesting their potential for promoting sustainability in plant populations.

Extreme temperatures, drought and salinity stress adversely affect seed germination and seedling growth in crop species. Seed priming has been recognized as an indispensable technique in the production of stress-tolerant plants. Seed priming increases seed water content, improves protein synthesis using mRNA and DNA and repair mitochondria in seeds prior to germination.

There is a continuous search for new chemical entities to expand the collection of suitable compounds to increase the efficiency of micropropagation protocols. Two cytokinin (CK) analogues, 2-chloro-6-(3-methoxyphenyl)aminopurine (INCYDE) and CK antagonist 6-(2-hydroxy-3-methylbenzylamino)purine (PI-55) were used as a tool to elucidate the auxin-CK crosstalk under in vitro conditions in the medicinally important plant, Eucomis autumnalis subspecies autumnalis. These compounds were tested at 0.

Eckol, a major phenolic compound isolated from brown seaweed significantly enhanced the bulb size and bioactive compounds in greenhouse-grown Eucomis autumnalis. We investigated the effect of eckol and phloroglucinol (PG) (phenolic compounds) isolated from the brown seaweed, Ecklonia maxima (Osbeck) Papenfuss on the growth, phytochemical and auxin content in Eucomis autumnalis (Mill.) Chitt.

The effect of 2-chloro-6-(3-methoxyphenyl)aminopurine [inhibitor of cytokinin degradation (INCYDE)] at 10 nM on growth, biochemical and photosynthetic efficiency in sodium chloride (NaCl)-stressed (75, 100 and 150 mM) tomato plants was investigated. NaCl-induced decline in plant vigor index was slightly reversed by both drenching and foliar application of INCYDE. Foliar application of INCYDE significantly increased the flower number in the control and 75 mM NaCl-supplemented plants, while drenching was more effective in 150 mM NaCl-stressed plants.

Article Synopsis
  • The genus Eucomis, used in African traditional medicine, includes 10 species that treat various ailments like respiratory issues, venereal diseases, and infections of the kidney and bladder.
  • Research indicates that Eucomis species possess numerous pharmacological benefits, showing antimicrobial, antitumor, and anti-inflammatory properties, with potential applications in both medicine and agriculture.
  • Conservation efforts are crucial due to overharvesting; while traditional methods have helped, micropropagation may be necessary to protect wild populations and further investigate the genus's toxicological aspects.
