Caffeoyl shikimate esterase (CSE) has been shown to play an important role in lignin biosynthesis in plants and is, therefore, a promising target for generating improved lignocellulosic biomass crops for sustainable biofuel production. Populus spp. has two CSE genes (CSE1 and CSE2) and, thus, the hybrid poplar (Populus alba × P. glandulosa) investigated in this study has four CSE genes. Here, we present transgenic hybrid poplars with knockouts of each CSE gene achieved by CRISPR/Cas9. To knockou

Grass xylan, the major hemicellulose in both primary and secondary cell walls, is heavily decorated with α-1,3-linked arabinofuranosyl (Araf) residues that may be further substituted at O-2 with xylosyl (Xyl) or Araf residues. Although xylan 3-O-arabinosyltransferases (XATs) catalyzing 3-O-Araf addition onto xylan have been characterized, glycosyltransferases responsible for the transfer of 2-O-Xyl or 2-O-Araf onto 3-O-Araf residues of xylan to produce the Xyl-Araf and Araf-Araf disaccharide sid

The functional elucidation of plant cell wall biosynthesis (CWB) related genes is important for understanding various stress tolerance responses as well as enhancing biomass in plants. Despite their significant role in physiology and growth of the plant, the function of a limited number of CWB related genes have been identified. Major obstacles such as functional redundancy and limited functional information pose challenges in the characterization of CWB genes. Here, a genome-wide analysis of CW

Vertical farming offers the advantage of providing a stable environment for plant cultivation, shielding them from adverse conditions such as climate change. For fruit-harvesting plants like tomato, vertical farming necessitates the optimization of plant growth and architecture. The gibberellin 3-oxidase (GA3ox) genes encode gibberellin 3-oxidases responsible for activating GA within the pathway and modulating stem length. Among the five SlGA3ox genes, we targeted the coding regions of three SlG

Optimizing plant architecture for specific cultivation methods is essential for enhancing fruit productivity. Unlike indeterminate growth plants, the total productivity of determinate growth plants relies on cumulative fruit production and synchronized fruit ripening from both main and axillary shoots. Here, we focused on SlD14 and SlMAX1, two key genes involved in the regulation of strigolactone (SL) signaling and biosynthesis, with the goal of maximizing yield and synchronizing fruit ripening
