A chloroplast envelope glycolate transporter and its involvement in photorespiratory metabolism
Plant Science Research Weekly, Research0 Comments
/
In C3 plants at ambient CO2 levels, Rubisco’s oxygenation reaction occurs about once for every three carboxylation reactions. One of the oxygenation products, 2-phosphoglycolate, is rapidly dephosphorylated to glycolate which is toxic and inhibitory to photosynthesis. Glycolate has to be removed from…
Mutations in Argonaute5 illuminate epistatic interactions of the K1 and I loci ($)
Plant Science Research Weekly, ResearchClassic studies revealed an interesting genetic relationship between two loci that control pigmentation in soybeans seeds. Dominant alleles of the I locus suppress pigmentation through the production of small interfering RNAs that target chalcone synthase RNA (an enzyme involved in pigment production).…

Living on the edge: conservation genetics of seven thermophilous plant species in a high Arctic archipelago
Plant Science Research Weekly, ResearchThe Arctic provides numerous opportunities to study how climate change and isolation affect plant populations. Birkeland et al. queried the genetic diversity within isolated populations of seven heat-loving (thermophilous) species in the high Arctic (74° – 81° N) Svalbard Archipelago, near the well-known…
Review: Wheat genomics comes of age
Plant Science Research Weekly, ResearchDue to its highly repetitive, polyploid genome, wheat genomics has lagged behind that of other cereals, but new tools promise to begin closing that gap. Uauy reviews these new tools, which include access to full genomes of several wheat varieties, gene expression data from hundreds of publicly available…

Signatures of local adaptation in lowland and highland teosintes from whole genome sequencing of pooled samples ($)
Plant Science Research Weekly, ResearchTeosinte, the ancestor of maize, grows in a range of environments in México. Teosinte parviglumis (Zea mays ssp parviglumis) is more prevalent in lowland regions while teosinte mexicana (Zea mays ssp mexicana) occupies highland territory (>2000 m above sea level). Admixture between parviglumis and…
Natural haplotypes of FLM non-coding sequences fine-tune flowering time in two ambient spring temperatures in Arabidopsis
Plant Science Research Weekly, ResearchDelaying reproduction until conditions are favorable is a key to success. FLOWERING LOCUS C is a well-known regulator of flowering that delays flowering until after winter vernalization. In the spring, FLOWERING LOCUS M (FLM) fine-tunes flowering time in response to ambient temperatures between 5ºC…
Mobile MUTE specifies subsidiary cells to build physiologically improved grass stomata ($)
Plant Science Research Weekly, ResearchPlants breathe through pores called stomata on leaf surfaces. Stomata are the point of contact with the outside world as they allow gas exchange (e.g., CO2 for photosynthesis) and transpiration. Grasses have evolved to form more efficient stomata in which the guard cells are flanked by additional subsidiary…
