Review: Homoeologous exchanges, segmental allopolyploidy, and polyploid genome evolution Polyploidy or whole-genome duplication (WGD) is an important process in plant evolution and speciation. Additional sets of chromosomes can be derived from intraspecific genome duplication (autopolyploidy) or…

Review: Optogenetics in plants Optogenetics is the process by which light can modify cellular behavior, through the action of light-sensitive proteins or other molecules. In many respects, optogenetics seems more like science fiction than reality; the realization that neural activity in the brain…

This week’s Plant Science Research Weekly was guest-edited by Batthula Vijaya Lakshmi Vadde. She is currently a postdoc at Adrienne Roeder’s lab, Cornell University studying giant cell patterning in Arabidopsis sepals. Vijaya did her Ph.D. on trichome development in Arabidopsis with Utpal Nath from…

Perspective: Multiplying the efficiency and impact of biofortification through metabolic engineering As heterotrophs, we are what we eat. One of the UN Sustainable Development Goals is to end all forms of hunger, including the “hidden hunger” that results from nutrient deficiencies. Van Der…

Review: The second decade of synthetic biology: 2010–2020 I guess if this were a normal year, we’d be spending time looking back over the past decade, but Covid-19 has made anything pre-2019 seem like a different lifetime. Still, here’s a retrospective you don’t want to miss. Meng and…

Review: Less is more, natural loss-of-function mutation is a strategy for adaptation Gene gain through duplication and gene loss through loss-of-function (LoF) mutations determine genetic variation underlying diversification and adaptive evolution. In this review, Xu and Guo highlight the importance…

Review: Dry architecture: towards the understanding of the variation of longevity in desiccation- tolerant germplasm ($) Most seeds, pollen grains, and fern spores are desiccation-tolerant, meaning they remain viable after drying to low water contents. Given this property, they can be stored in cold…

Review: The hornworts: morphology, evolution and development Bryophytes and vascular plants share a land plant as a common ancestor, but they have evolved independently for more than 400 million years. Recent genomic studies of model bryophytes, particularly mosses and liverworts, have provided insights…
