Effect of exogenous amino acids application on the biochemical, antioxidant, and nutritional value of some leafy cabbage cultivars.

Using organic fertilizer as part of plant nutrition for decreasing using chemical fertilizer and increasing plants' nutritional value is scientists' concern. Treatments were three concentrations of a mixture of 16 different AAs (amino acid) (0, 150 and 300 mg/L), sprayed every 7 days for 2 months on 4 leafy cabbages. Results showed 300 mg/L AAs increased anthocyanin, flavonoids, phenol, protein and proline.

Global identification of long non-coding RNAs involved in the induction of spinach flowering.

Background: Spinach is a beneficial annual vegetable species and sensitive to the bolting or early flowering, which causes a large reduction in quality and productivity. Indeed, bolting is an event induced by the coordinated effects of various environmental factors and endogenous genetic components. Although some key flowering responsive genes have been identified in spinach, non-coding RNA molecules like long non-coding RNAs (lncRNAs) were not investigated yet.

Transcriptome architecture reveals genetic networks of bolting regulation in spinach.

Background: Bolting refers to the early flowering stem production on agricultural and horticultural crops before harvesting. Indeed, bolting is an event induced by the coordinated effects of various environmental factors and endogenous genetic components, which cause a large reduction in the quality and productivity of vegetable crops like spinach. However, little is known about the signaling pathways and molecular functions involved in bolting mechanisms in spinach.

Transcriptome and phytochemical analyses provide insights into the organic sulfur pathway in Allium hirtifolium.

Allium is one of the well-known genera of the Amaryllidaceae family, which contains over 780 species. Onions, garlic, leeks, and shallots are the most important species of this genus. Allium hirtifolium (shallot) is a rich source of proteins, carbohydrates, lipids, amino acids, and bioactive compounds such as organic sulfur compounds with an expansive range of biological activities and medicinal attributes.

Grafting of watermelon (Citrullus lanatus cv. Mahbubi) onto different squash rootstocks as a means to minimize cadmium toxicity.

To test the possibility that using appropriate rootstocks could improve the tolerance of watermelon to cadmium (Cd) toxicity, a greenhouse experiment was conducted to determine growth and antioxidant activities of watermelons, either nongrafted or grafted onto summer squash and winter squash. We provided nutrient solutions having four levels (0, 50, 100, and 200 μM) of cadmium to treat the plants. Shoot and root biomass reduction were significantly lower in summer squash rootstock-grafted watermelon than winter squash rootstock-grafted and nongrafted watermelons.
