Bahd Acyltransferase

The purification of hydroxycinnamic acids [p-coumaric acid (pCA) and ferulic acid (FA)] from grass cell walls requires high-cost processes. Feedstocks with increased levels of one hydroxycinnamate in preference to the other are therefore highly desirable. We identified and conducted expression analysis for nine BAHD acyltransferase ScAts genes from sugarcane. The high conservation of AT10 proteins, together with their similar gene expression patterns, supported a similar role in distinct grasses. Overexpression of ScAT10 in maize resulted in up to 75% increase in total pCA content. Mild hydrolysis and derivatization followed by reductive cleavage (DFRC) analysis showed that pCA increase was restricted to the hemicellulosic portion of the cell wall. Furthermore, total FA content was reduced up to 88%, resulting in a 10-fold increase in the pCA/FA ratio. Thus, we functionally characterized a sugarcane gene involved in pCA content on hemicelluloses and generated a C4 plant that is promising for valorizing pCA production in biorefineries.

Nutritional Potential

Forage cell wall content (CWC), accounting for 400 to 600 g kg-1 dry matter (DM) (Van Soest, 1982) and its rumen degradability (CWD) are major factors influencing the animal's energy supply from forages. Therefore, in order to maximise the nutritional potential of forages for ruminants, the ability to accurately and rapidly measure CWD is crucial. This is becoming increasingly important as feed evaluation methods move towards assessing nutrient supply. While the measurement of CWD is largely based on the polyester bag technique an experiment was undertaken to study the potential of measuring CWD in vitro for different forage types.Three methods of measuring CWD were compared using four samples each of grass (G), grass silage (GS), maize silage (MS) and straw (S) in a factorial design. The methods were; 1) fresh (undried) forage, chopped to 1 cm lengths using an homogeniser, was incubated in the rumens of sheep in polyester bags (pore size 43um) for different lengths of time (0, 3, 8, 16, 24, 45 and 72h).
