Li et al. examine heat-induced SUMOylation of bacteria effectors in Arabidopsis. (Plant Cell. 2024) By Wenliang Li and Jianbin Lai (South China Normal University) https://doi.org/10.1093/plcell/koae049 Background: Bacterial pathogens deliver effectors into plant cells to interfere with host…

Behind the Plant Physiology manuscripts are researchers, professors, professionals and students dedicated to advancing the field of plant science. You’ve seen our First Authors on Twitter and Facebook— now, read more about why they chose to pursue plant sciences and click on the links below the pictures…

Roots do not grow in isolation but occupy a space inhabited by a variety of organisms. With certain fungi and bacteria, they form partnerships or symbiotic relationships that increase the plant’s nutrient uptake and assimilation. While the knowledge on the genetic programs required to establish these…

An efficient method of gene downregulation, where gene expression is reduced but not completely knocked out, is useful for crop improvement. Here, Shen et al. have developed a system to achieve this, by using CRISPR/Cas9 to insert an element containing a Kozak sequence and an ATG start codon just before…

I think one of the most important lessons a scientist learns is to cross-check their findings with a different approach in order to determine if the findings are reasonable. This interesting article by Oliveira-Filho and Campos-Silva et al. lays out several examples of using back-of-the envelope or Fermi…

In the dazzling dance of plant cellular life, chloroplasts must groove in harmony with growth to sidestep the perils of photooxidative damage. This harmony between photosynthesis and photooxidative damage is orchestrated by the guanosine tetraphosphate (ppGpp) signalling pathway which traces its roots…

Many bryophytes and other non-seed plants are tolerant to vegetative desiccation, which is thought to have been necessary for colonization of land. By contrast, most seed plants lack this capacity, although they retain desiccation tolerance in their pollen and seeds. However, some seed plants, known…

Wheat (Triticum aestivum) is an important crop, making up ~20% of food consumed worldwide. As the population grows, wheat yields must increase to meet demand. To achieve this, genetically diverse wheat landraces (aka traditional varieties, which are locally adapted cultivars) can be utilized. Here, Cheng…
