Review: Changing form and function through carotenoids and synthetic biology (Plant Physiol)

Plants produce hundreds of carotenoids with functions ranging from photoprotection to signalling, and with important roles in human health as well. Wurtzel describes opportunities arising from applying the tools of synthetic biology to carotenoids. The regulation of carotenoid biosynthesis is complex, and one key challenge is to identify switches to modulate the flow of intermediates […]

Desiccation tolerance evolved through gene duplication and network rewiring in Lindernia (Plant Cell)

Desiccation tolerance is the property of being able to survive and recover from extreme dehydration. Although there are many desiccation-tolerant plant species, efforts to identify the genetic basis of desiccation tolerance have been limited by a lack of closely-related desiccation sensitive species. VanBuren et al. compared two species of Lindernia, one of which is desiccation […]

The imprinted gene PEG2 acts as a sponge for the transposon-derived siRNA854, inducing postzygotic reproductive isolation (Devel. Cell)

Closely related species that have different numbers of chromosomes (e.g., 2n versus 4n) are reproductively isolated, and this can arise as a consequence of an unbalancing in the expression levels of maternally- and paternally-imprinted genes. Wang et al. have identified a fascinating mechanism that explains why the seeds of different-ploidy hybrids frequently abort. The authors […]

Transcriptional regulation of the immune receptor FLS2 controls the ontogeny of plant innate immunity (Plant Cell)

FLS2 is a well-known cell-surface receptor that triggers plant immune response. Zou et al. asked whether its expression level is age-dependent, and found that FLS2 is expressed at very low levels in newly-emerged seedlings. They identified two closely related transcription factors TOE1 and TOE2 that negatively regulate FLS2 expression and FLS2-mediated immunity in very young […]

JAZ repressors of metabolic defense promote growth and reproductive fitness in Arabidopsis (Proc. Natl. Acad. Sci. USA)

Jasmonates promote defense reponses but at the expense of growth. JAZ proteins repress jasmonate responses. Guo et al. examined the consequences of knocking out 10 of the 13 JAZ genes in Arabidopsis, by producing a jaz decuple, or jazD mutant. They compared jazD mutant to previously described jazQ mutants that have five JAZ genes knocked […]
