Introduction
We proposed Cl- to be a beneficial macronutrient that improves plant growth, water balance, chloroplast organogenesis, drought resistance, WUE and NUE. My Ph. D. happily ended in July 2022 (Cum Laude!), including 4 papers and a review. Since I am finishing it (last 2 years), I have been technical director of R&D in Agriculture with Ozone Application and a researcher in the R&D department of a food biotechnology-based company. Nowadays I head the hygiene quality department at the HUPR Hospital.

Chloride (Cl–) is a micronutrient that accumulates to macronutrient levels since it is normally available in nature and actively taken up by higher plants. Besides a role as an unspecific cell osmoticum, no clear biological roles have been explicitly associated with Cl– when accumulated to macronutrient concentrations. To address this question, the...

Three biochars (B1: pine wood, B2: paper-sludge, B3: sewage-sludge) produced under controlled pyrolysis conditions and one produced in kilns (B4: grapevine wood) were used as organic ameliorants in a Calcic Cambisol, which represents a typical agricultural soil of the Mediterranean region. This field study was performed with plants of sunflower (He...

Chloride (Cl⁻) has been recently described as a beneficial macronutrient, playing specific roles in promoting plant growth and water use efficiency (WUE). However, it is still unclear how Cl⁻ could be beneficial, especially in comparison with nitrate (NO3⁻), an essential macronutrient that shares with Cl⁻ similar physical and osmotic properties, as...

The chloride anion (Cl-) has traditionally been considered a detrimental element for agriculture due to its antagonism with the nitrate anion (NO3-), and its toxicity when it accumulates in high concentrations in salinity conditions. On the other hand, Cl- is an essential micronutrient for higher plants, being necessary in small traces to fulfill a...

In this popular science article, we tell the story of the curious life of the jellyfish Turritopsis nutricola/dohrnii, a jellyfish capable of reversing its life cycle as an adult jellyfish and returning to the polyp phase, thus living forever and generating clones of itself. We not only explain the biology of the jellyfish but also take a fun cultu...

From ancient times, one of the aquatic areas of greatest human interest has been the marshes. Their connection to the sea, as well as being the estuary of rivers and an area rich in resources, has meant that they are not only an ecosystem with a wide variety of species but also regions where the probability of colonisation by invasive species is qu...

Chloride (Cl−), traditionally considered harmful for agriculture, has recently been defined as a beneficial macronutrient with specific roles that result in more efficient use of water (WUE), nitrogen (NUE), and CO2 in well-watered plants. When supplied in a beneficial range of 1-5 mM, Cl− increases leaf cell size, improves leaf osmoregulation, and...

Stephen Jay Gould was born on 10 September 1941 in the Bayside community of Queens, New York, and was raised in a secular (non-practising) Jewish home, hence he considered himself agnostic all his life.

Ozone therapy is the use of Ozone (O3) for medical purposes for the treatment of infectious diseases or diseases of various kinds (take a look at all the publications by Velio Bocci, a researcher at the University of Siena, Italy). The basic mechanism of action is due to its properties as (i) biocide, with the inactivation of viruses, bacteria, fun...

Seedlings are more sensitive to ozone than adult plants, but there are several papers that reports a beneficial effect in seedlings treated with ozone. This has a great relevance in the ornamental plants market and in agriculture.

Chloride (Cl−) nutrition at macronutrient levels significantly increases the size of leaf cells, resulting in a reduction in stomatal density and, therefore, conductance (gs). At the same time, Cl− improves mesophyll diffusion conductance to CO2 (gm) due, at least in part, to increased surface area of chloroplasts exposed to the intercellular airsp...

Plants are planted in peat. The aerial part (stems, leaves...) is cut with a scalpel. The pots are then immersed in irrigation solution and hermetically sealed. We obtain the drops that sprout from the xylem sap at different times (1h, 2h, 3h, 5h). You can measure the ions of interest in the xylem, the volume, sugars, and other elements. For more...

Cl-is a strange micronutrient since actual Cl-concentration in plants is about two orders of magnitude higher than the content required as essential micronutrient.
