“…Importantly, the mutation – to a gene which appears to encode for a member of the sulfate transporter gene family (Ye et al, 2011) – appears to have a seed-specific impact by reducing endosperm P levels by 30% (Ockenden et al, 2004) without broader negative effects on plant physiological processes. The fact that commercial barley cultivars have been developed and released in North America (Bregitzer et al, 2007) suggests that reducing the P concentration of cereal crops by around 20% through breeding without reducing subsequent crop yields is certainly feasible.…”

Given the non-renewable nature of global phosphate reserves, there is a push to increase the phosphorus (P) efficiency of agricultural crops. Research has typically focussed on investigating P acquisition efficiency or internal P utilization efficiency to reduce crop fertilizer requirements. A novel option that would reduce the amount of P exported from fields at harvest, and may ultimately reduce P fertilizer requirements, would be to reduce the amount of P translocated to grains to minimize grain P concentrations. While such a trait has been mentioned in a number of studies over the years, there has not been a concerted effort to target this trait in breeding programs. In this perspective piece we explore the reasons why a low grain P trait has not been pursued, and discuss the potential benefits and drawbacks of such a trait in the context of breeding to improve the P efficiency of cropping systems.

“…This has led to mutant lines with PA content ranging from 80 % down to 10 % of the parent line. In some cases, these mutants have been advanced to the stage where they have been registered as cultivars or germplasm in the U.S.A. [53,54]. In many of these mutants, characterization and identification of the underlying genes resulting in the lpa phenotype has contributed significantly to our understanding of the PA biosynthetic pathway in plants, even if there are still gaps in our knowledge.…”

Mutations in genes controlling the biosynthesis and accumulation of inositol phosphates in seeds

Most of the phosphorus in the resting seed is stored inside protein storage vacuoles as PA (phytic acid; InsP(6)). The biosynthesis and accumulation of PA can be detected beginning from a few days after anthesis and seem to continue during seed development until maturation. The first step in PA biosynthesis is the formation of Ins3P by conversion of glucose 6-phosphate. This is then followed by a sequential and ordered phosphorylation of the remaining five positions of the inositol ring by a number of kinases, resulting in PA. Identification of low-PA mutants in cereals, legumes and Arabidopsis is instrumental for resolving the biosynthetic pathway and identification of genes controlling the accumulation of PA. Mutations in seven genes involved in the metabolism of PA have been identified and characterized among five plant species using induced mutagenesis and insertion elements. Understanding the biosynthetic pathway and genes controlling the accumulation of PA in plant seeds and how PA may balance the free phosphate is of importance for molecular breeding of crop plants, particularly cereals and legumes.

“…However, the association of low phytate with poor agronomic performance is not absolute (Raboy et al, 2015), and recurrent selection has resulted in signiicant improvement. Low-phytate barley germplasm and cultivars have been released that have reasonably good performance compared with widely grown feed barley cultivars (Bregitzer et al, 2007(Bregitzer et al, , 2008(Bregitzer et al, , 2010Rossnagel et al, 2008). PI 676261) is the most recent hulled, low-phytate barley to be developed and released by the USDA-ARS.…”

Registration of ‘Harriman’ Low‐Phytate, Hulled Spring Barley

‘Harriman’ (Reg. No. CV‐358, PI 676261) is a hulled, low‐phytate barley (Hordeum vulgare L.) cultivar, the second to be developed and released by the USDA‐ARS. Compared to the previously released hulled, low‐phytate cultivar, ‘Herald’, Harriman has higher grain yield, higher test weight, higher inorganic phosphorus (Pi), and lower phytate phosphorus (P). This cultivar can contribute to animal production and sustainable agriculture by reducing or eliminating the need for P or phytase supplementation and by reducing the amount of P released into the environment from animal production facilities.
