Herbivores use symbiotic microbes to help derive energy and nutrients from plant material. Leaf-cutter ants are a paradigmatic example, cultivating their mutualistic fungus Leucoagaricus gongylophorus on plant biomass that workers forage from a diverse collection of plant species. Here, we investigate the metabolic flexibility of the ants’ fungal cultivar for utilizing different plant biomass. Using feeding experiments and a novel approach in metaproteomics, we examine the enzymatic response of L. gongylophorus to leaves, flowers, oats, or a mixture of all three. Across all treatments, our analysis identified and quantified 1,766 different fungal proteins, including 161 putative biomass-degrading enzymes. We found significant differences in the protein profiles in the fungus gardens of sub-colonies fed different plant substrates. When provided with leaves or flowers, which contain the majority of their energy as recalcitrant plant polymers, the fungus gardens produced more proteins predicted to break down cellulose: endoglucanase, exoglucanase, and β-glucosidase. Further, the complete metaproteomes for the leaves and flowers treatments were very similar, while the mixed substrate treatment closely resembled the treatment with oats alone. This indicates that when provided a mixture of plant substrates, fungus gardens preferentially break down the simpler, more digestible substrates. This flexible, substrate-specific enzymatic response of the fungal cultivar allows leaf-cutter ants to derive energy from a wide range of substrates, which likely contributes to their ability to be dominant generalist herbivores.

“…Among the major cereal crops, oat grain is characterized by particularly valuable chemical composition. Both nutrients and non-nutrients present in oat grain determine its considerable value for human and animal nutrition (PETERSON 2001, BARTNIKOWSKA 2003, GAMBUOE et al 2003, CUDDEFORD 1995. Until relatively recently, oat grain has been used almost exclusively for oatmeal manufacturing, whereas nowadays it is also raw material sought for health-related foods, medicines and highly valued cosmetics (PETERSON 2004, GAMBUOE et al 2003.…”

Among the cereals grown in Poland, oat grain contains the highest amount of ash, composed of macro-and microelements. It has been suggested that applying increased levels of mineral fertilization, to newer cultivars of oat could have an impact on their grain yield and mineral composition. A two-factorial (2x2) field experiment was conducted for three years (1999-2001) in the south of Poland. The experiment involved two cultivars of oat, i.e. the covered cultivar Dukat and the naked cultivar Akt, and two fertilization levels, i.e. low (30 kg N, 30 kg P 2 O 5 and 45 kg K 2 O ha-1) and high (60 kg N, 60 kg P 2 O 5 and 90 K 2 O ha-1). There was no significant difference in grain yield between the studied cultivars. On the other hand, the high NPK level increased the content of Mg and Fe in the grain of Akt. At the same time, there were no significant differences in the grain content of Cu, Fe, Mn and Zn between Dukat and Akt. Overall, the high level of mineral fertilizing decreased the grain content of microelements as a result of dilution effect. The content of Cu and Zn in oat grain was suitable for human consumption according to the IUNG-PIB standards. Generally, it was shown that cv. Akt was richer in mineral elements, especially in P, K, Ca, Mg, Fe and Zn, than cv. Dukat.

“…Mulholland et al (1994) showed DM intake for oats, wheat and barley straw with sheep to be 660, 450 and 320 g/day, which indicates a large variability in the nutritive value of cereal crop residues. Cuddeford (1995) suggested that oat straw has higher digestible organic matter (OM) and metabolizable energy (ME) contents than other cereals in terms of available energy. He also suggested that oat straw is the most palatable and nutritious, followed by barley straw, wheat straw and rye straw.…”

Yield, chemical composition, in vitro digestibility and kinetics of fermentation of straw from 18 varieties of oats (Avena sativa L.) were studied. All the straw varieties were grown in three replicates under the same agronomic conditions. Significance differences were observed in the yield of straw (4.4 to 7.5 ton dry matter (DM)/ha) from different varieties. The proportion of seed/straw from these varieties varied from 0.28 to 1.02. Crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (ADF) and acid detergent lignin (ADL) content varied from 24.2 to 48.1, 626 to 708, 437 to 533 and 52.0 to 92.4 g/kg DM, respectively in the straws. In vitro organic matter digestibility (IVOMD) differed among varieties and varied from 400 to 539 g/kg DM. The mean value of digestible organic matter yield (DOM) was 2.34 ton/ha. A significant difference was observed in the potential gas production (A) and lag time (L) among varieties. The fractional rate of gas production (c, /h) ranged from 0.030 to 0.034. The results emphasized that in any evaluation of oat varieties, kinetics of digestion or fermentation should be taken into consideration as well as yield and digestibility._________________________________________________________________________________
