Identification of calmodulin-dependent NAD+ kinase that sustains the elicitor-induced oxidative burst (Plant Phys)
Plant Science Research WeeklyWhen pathogens attack, one line of defense is the production of a burst of reactive oxygen species (ROS) which triggers additional defences. ROS is produced by the action of NADPH oxidases, which require NADPH as a substrate; NADPH is derived from NADP+, but where does this come from? Previous studies…
NODULE INCEPTION recruits the lateral root developmental program for symbiotic nodule organogenesis in Medicago truncatula ($) (Curr Biol)
Plant Science Research WeeklyLateral roots are secondary root organs arising through the dedifferentiation of inner cell layers in the primary root. Nodules arise through symbiosis with rhizobia bacteria in a certain clade of land plants and they also arise through dedifferentiation. Both lateral roots and nodules are part of the…
High-resolution expression profiling of selected gene sets during plant immune activation (bioRxiv)
Plant Science Research WeeklyThe problem with gene expression profiling is that it preferentially reports on the more highly-expressed genes. Capture sequencing uses targeted sequence libraries to pull out transcripts from genes of interest, including lowly expressed genes, so that their signals aren’t overwhelmed. To explore…
NEEDLE1 encodes a mitochondria localized ATP-dependent metalloprotease required for thermotolerant maize growth ($) (PNAS)
Plant Science Research WeeklyPreviously, the needle1 (ndl1) maize mutant was identified as showing a variable phenotype mainly affecting the tassel. Here, Liu et al. showed that this variability arises due to its temperature sensitivity, with strongest effects at warmer temperatures. In some cases, the plants arrest before reaching…
Plant Science Research Weekly: October 4th
Blog, WWR Full PostLetter. The human health benefits from GM crops
If you’ve ever spoken publicly about GM crops, you’ve probably heard people express concern about how eating GM crops might affect their health. Smyth lays out a positive case for the human health benefits of GM crops, which will be a useful resource…
Ray parenchymal cells contribute to lignification of tracheids in developing xylem of Norway spruce (Plant Phys)
Plant Science Research WeeklyLignin makes up to 27% of the dry weight of wood and is important structurally as well as serving as an effective carbon sink. Lignin is produced from monolignol precursors that are released into the apoplast and then polymerized. Previous studies have suggested that the monolignols are produced not…
