“…Arnold . Fructans are known to be abundant in immature wheat kernels and similar reduction rates of 50-90% have been reported for mature wheat when compared to immature kernels [30]. However, it has to be pointed out that in the present study only low molecular weight fructans (GF2-GF4) have been determined.…”

Background Recent gastroenterology studies assume that amylase-trypsin inhibitors (ATIs) and FODMAPs (fermentable oligo-, di-, monosaccharides and polyols) play an important role in promoting wheat sensitivity. Hitherto, no study has investigated the formation of ATIs during the development of the wheat caryopsis. We collected caryopses of common wheat cv. ‘Arnold’ at eight different grain developmental stages to study compositional changes in ATI and FODMAP content. Results The harvested caryopses were analysed for their size, protein and carbohydrate concentrations. ATIs were further characterized by MALDI-TOF MS, and their trypsin inhibition was evaluated by an enzymatic assay. The results showed that ATI accumulation started about one week after anthesis and subsequently increased steadily until physiological maturity. However, the biological activity of ATIs in terms of enzyme inhibition was not detectable before about four weeks after anthesis. Carbohydrate analysis revealed the abundance of short-chain fructans in early stages of grain development, whereas non water soluble carbohydrates increased during later developmental stages. Conclusions The compositional changes of ATIs and FODMAPs during the development of wheat grains were characterized by qualitative and quantitative approaches. The results provide new insights into the complex metabolisms during grain filling and maturation, with particular emphasis on the ATI content as well as the inhibitory potential towards trypsin. The time lag between ATI accumulation and development of their biological activity is supposed to be attributed to the assembling of ATIs to dimers and tetramers, which seems to be crucial for their inhibitory potential.

“…This contribution of the Suc flux from the stem to the wheat kernel seems relatively more important for yield maximization under terminal drought (see section Introduction). The Suc gradient between stem and kernels might be sustained by the fructan synthesis occurring in the milky stages (Paradiso et al 2008). Later on, fructans are remobilized to feed starch anabolism in the kernel.…”

Remobilization of stored carbohydrates in the stem of wheat plants is an important contributor to grain filling under drought stress (DS) conditions. A massive screening on Iranian wheat cultivars was performed based on stem dry weight changes under well-watered and DS conditions. Two cultivars, Shole and Crossed Falat Hamun (CFH), with different fructan accumulation and remobilization behavior were selected for further studies. Water-soluble carbohydrates (WSCs) and fructan metabolizing enzymes were studied both in the stem penultimate and in sucrose (Suc) treated, excised leaves. Under drought, CFH produced higher grain yields than Shole (412 vs 220 g m(-2)). Also, grain yield loss under drought was more limited in CFH than in Shole (17 vs 54%). Under drought, CFH accumulated more graminan-type fructo-oligosaccharides than Shole. After anthesis, fructan 6-exohydrolase (6-FEH; EC 3.2.1.154) activities increased more prominently than fructan 1-exohydrolase (EC 3.2.1.153) activities during carbon remobilization. Interestingly, CFH showed higher 6-FEH activities in the penultimate than Shole. The field experiment results suggest that the combined higher remobilization efficiency and high 6-FEH activities in stems of wheat could contribute to grain yield under terminal drought. Similar to the penultimate, fructan metabolism differed strongly in Suc-treated detached leaves of selected cultivars. This suggests that variation in the stem fructan among wheat cultivars grown in the field could be traced by leaf blade induction experiments.

“…However, Paradiso et al (2008) reported maximum values for fructan contents of about 11% and 16% on average for stems and grain, respectively, of 45 cultivars of durum wheat. Our experimental data suggest that these cereals, which are well adapted and widely cultivated in the area of the study, can be used for the production of green feed rich in FOS.…”

During growth, several cereals store significant amounts of fructo-oligosaccharides (FOS), which have important prebiotic properties. Cereal forage crops are also essential components of many Mediterranean agricultural systems, although little information is available on their dynamics of accumulation and partitioning of dry matter and FOS during growth. Oat (Avena sativa L., cv. 'Flavia' and cv. 'Genziana'), emmer wheat (Triticum dicoccum Schrank, cv. 'Giovanni Paolo'), barley (Hordeum vulgare L., cv. 'Diomede') and triticale (xTriticosecale Wittmack, cv. 'Rigel') were investigated for their synthesis of FOS, with a view to development of management approaches for harvesting high-quality forage, and to determine whether these species can be used as natural sources of FOS for commercial use. The study was conducted at Foggia (Italy) and Bella (Potenza, Italy) over two growing seasons (). Dry-matter accumulation and FOS contents were determined for plant fractions from heading to kernel-hard stages. There were large variations across these species for dry-matter partitioning and dry-matter yield (greatest for triticale: 1.24 kg m −2 ), and for FOS levels of total plants and plant fractions. Emmer wheat and triticale showed greater FOS production (52.0, 41.1 g m −2 , respectively). Barley, emmer wheat and triticale showed higher FOS levels in total plants (4.11%, 5.93%, 4.33% dry matter, respectively). Barley, emmer wheat and triticale appear to be the most interesting species for production of forage biomass rich in FOS and as natural FOS sources for industrial use.
