“…The uptake and adaptability of L. minuta has led to its use as a wastewater detoxifying/phytoremediation species (Fernández et al, 2020). Wastewaters are often contaminated with a variety of toxic compounds yet the exact mechanisms of plants ability to adapt to these compounds, including high levels of essential elements and heavy metals, remains unclear (Frick, 1985; Davis et al, 2002; Del-Campo Marín and Oron, 2007; Gür et al, 2016; Liu et al, 2018; Türker et al, 2019). We find increased expression of BORON TRANSPORTER 4 ( BOR4 ) in the mesophyll and replicating cells (Fig.…”

The ability to trace every cell in some model organisms has led to the fundamental understanding of development and cellular function. However, in plants the complexity of cell number, organ size and developmental times makes this a challenge even in the diminutive model plant Arabidopsis thaliana. Here we develop the Lesser Duckweed Lemna minuta as a model with a reduced body plan, small genome size and clonal growth pattern that enables simultaneous tracing of cells from the entire plant over the complete developmental cycle. We generated a chromosome-resolved genome for the 360 megabase genome and defined the growth trajectory of the entire plant with single nuclei RNA sequencing. The L. minuta gene complement represents a primarily non-redundant set with only the ancient tau whole genome duplication shared with all monocots, and paralog expansion as a result of tandem duplications related to phytoremediation. Thirteen distinct cell types representing meristem, the leaf-stem fusion called a frond, and root-like tissues were defined using gene orthology with single cell expression from model plants, gene ontology categories, and cell trajectory analysis. Dividing meristem cells give rise to two main branches of root-transition and mesophyll cells, which then give rise to terminally differentiated parenchyma, epidermal and root cells. Mesophyll tissues express high levels of elemental transport genes consistent with this tissue playing a role in L. minuta wastewater detoxification. The L. minuta genome and cell map provide a paradigm to decipher developmental genes and pathways for an entire plant.

“…It was reported that high amounts of boron caused teratogenic effect and toxicity [35][36][37]. For instance, [38] reported that the initial boron concentration reaching up to 20 mg L-1 was toxic for L. minor at 6 days. In a separate study, [22] studied L. gibba and they found that higher than 25 mg B L -1 initial concentrations caused boron toxicity symptoms in 7 days.…”

In this paper, phytoremediation performance of Lemna minor L. on boron (B) removal from synthetic solution and real geothermal brine was evaluated. Effects of B concentration, initial pH, water height in cell, and initial humic acid concentration were investigated. The maximum removal efficiency was 96.7 % with the experimental run with B concentration of 5 mg L -1 , pH 8, and 1.5 cm water depth. Increasing the B concentration from 5 to 30 mg L -1 resulted in a drastic decrease in removal efficiency to 36.6 %, due to the toxic effect of high boron content, which was clearly observed from deterioration of plant's color and structure. SEM, FTIR, and mass balance analyses revealed that the boron removal mechanism was mainly biosorption. Geothermal water experiments indicated L. minor's applicability with 59.5% removal efficiency, proving high potential in being used for post-treatment of geothermal waters with high boron content.

“…Previous studies have shown the ability of duckweed to tolerate and remove B under different conditions. For example, Lemna minor , a widespread species of duckweed, was shown to tolerate and accumulate B differently under various conditions 11 . Spirodela polyrrhiza , another species of duckweed (also called greater duckweed), reportedly had different growth responses to B toxicity at different initial B concentrations 12 .…”

Boron accumulation by Lemna minor L. under salt stress

Excess boron (B) is toxic to aquatic organisms and humans. Boron is often present in water with high salinity. To evaluate the potential of duckweed (Lemna minor L.) for removing B from water under salt stress, we cultured duckweed in water with 2 mg/L of B and sodium chloride (NaCl) concentrations ranging from 0 to 200 mM for 4 days. The results show that with increasing salinity, the capacity of L. minor to accumulate B initially decreased and then increased. L. minor used different mechanisms to accumulate boron at lower and higher levels of salt stress. The growth and chlorophyll synthesis of L. minor were significantly inhibited when the concentration of NaCl reached 100 mM. Our results suggest that L. minor is suitable for the accumulation of B when NaCl salinity is below 100 mM.
