Genes and gene clusters related to genotype and drought-induced variation in saccharification potential, lignin content and wood anatomical traits in Populus nigra†

Abstract: Wood is a renewable resource that can be employed for the production of second generation biofuels by enzymatic saccharification and subsequent fermentation. Knowledge on how the saccharification potential is affected by genotype-related variation of wood traits and drought is scarce. Here, we used three Populus nigra L. genotypes from habitats differing in water availability to (i) investigate the relationships between wood anatomy, lignin content and saccharification and (ii) identify genes and co-expressed … Show more

“…The poly-A mRNA was fragmented for 1.5 minutes at 94 °C and all purification steps were performed using 1X Agencourt AMPure XP beads. Library quality and quantity were assessed using the Agilent Bioanalyzer 2100 High Sensitivity and Qubit DNA High Sensitivity (Invitrogen) as described more in detail in 53 . Libraries were pooled together, and the obtained pool checked on an Agilent Bioanalyzer 2100 in order to determine the molarity.…”

“…Poplar, in particular, was intensely studied [46,47]. Cambial cell layers are reduced under drought compared to well-watered plants [10,48]. When growth is still possible under water-limited conditions, poplars, regardless of whether they originate from dry or moist habitats, show reduced vessel lumina and an increased number of vessels compared to non-stressed plants (Populus x canescens, [49]; Populus euphratica, [11]; different Populus nigra genotypes originating from dry and moist areas, [10]), Figure 3).…”

“…As a result, vessel lumina decrease [9]. To counteract the reduction in hydraulic conductivity per vessel plants can increase the number of vessels in their xylem [9][10][11]. In this review, we will summarize the current knowledge on the molecular regulation of xylem acclimation in angiosperms with the focus on Populus species and identify knowledge gaps.…”

“…() constructed co‐regulation networks inferred from protein–DNA interactions to refine the SCW regulatory network under abiotic stresses in Arabidopsis and highlighted new key regulators. In poplar, co‐expression networks were used to identify cell‐type‐specific TFs involved in the regulation of SCW biosynthesis in xylem (Shi et al ., ), and modules of genes involved in xylem formation under abiotic stresses (Cai et al ., ; Zinkgraf et al ., ; Wildhagen et al ., ). Mizrachi et al .…”
