“…Von Proskowetz ( 1894 ) reported the following mean measures for sea beet roots: weight 147 g; length 35 cm; diameter 3.7 cm; sugar content 4.5%. Srivastava et al ( 2000 ) observed morphological traits from 34 populations of sea beet accessed from different countries and grown in northern India (Table 3.1 ). The root system of sea beet is often very expanded and deep.…”

The traits of Beta maritima have been reviewed and summarized from a number of recent and classical publications dealing with the ecology, morphology, and whole-plant physiology of the species. Because few papers have been written only on sea beet, B. maritima , most information comes from cultivated forms of Beta vulgaris . A striking feature of B. maritima gleaned from this review is how variable and adaptive it is. The species is fairly plastic allowing it to live in many different environments. This capacity for adaptation has been correlated with its breeding system, which allows sea beet to rapidly change reproduction systems, fl owering time, life span, etc. according to the local environmental conditions. This is most evident to the observer in the differences between the Mediterranean populations with easy bolting, short life cycles, and those from the sea coasts of northwest Europe. This chapter provides the reader with a comprehensive overview of the plant and populations to answer the question: "What is B. maritima ?"

“…maritima) is a wild relative of sugar beet (Lange et al, 1999). Sea beet grows in coastal and dry areas and can tolerate high concentrations of salt (Srivastava et al, 2000). Salt tolerance comparisons between sugar beet cultivars and their ancestor, sea beet, showed that sea beet had a higher salt tolerance than the sugar beet cultivars (Rozema et al, 2015).…”

Salinity stress has a negative impact on plant growth, which affects homeostasis and productivity. The uptake of nonessential salt ions changes the osmotic balance of the cell and causes dehydration. Higher plants develop salt tolerance mechanisms to avoid dehydration. Sea beet (Beta vulgaris subsp. maritima) is a halophytic ancestor of cultivated sugar beet that displays salt stress tolerance. In this study, we screened a B. vulgaris subsp. maritima cDNA library in Saccharomyces cerevisiae strain Ab11c (ena1Δ, nha1/4Δ, nhx1Δ), which is deficient in sodium transport, to find sodium-detoxifying genes. We identified a cDNA construct, named BETA1, providing salt tolerance to yeast cells. This gene had no previously described function. Intracellular sodium measurements demonstrated no significant differences between yeast cells expressing BETA1 or a sham vector, suggesting that sodium was not effluxed in BETA1-expressing cells. Transcriptionally, BETA1 mRNA levels were induced immediately in leaves and later in the root system in response to the salt stress. Our results suggest that the BETA1 gene is part of the salt tolerance network in B. vulgaris subsp. maritima.
