“Targeted Sequencing by Gene Synteny,” a New Strategy for Polyploid Species: Sequencing and Physical Structure of a Complex Sugarcane Region

open access: yesFrontiers in Plant Science, 2018
Sugarcane exhibits a complex genome mainly due to its aneuploid nature and high ploidy level, and sequencing of its genome poses a great challenge. Closely related species with well-assembled and annotated genomes can be used to help assemble complex ...

The “Polyploid Hop”: Shifting Challenges and Opportunities Over the Evolutionary Lifespan of Genome Duplications

open access: yesFrontiers in Ecology and Evolution, 2018
The duplication of an entire genome is no small affair. Whole genome duplication (WGD) is a dramatic mutation with long-lasting effects, yet it occurs repeatedly in all eukaryotic kingdoms. Plants are particularly rich in documented WGDs, with recent and

Diploid origins and early genome stabilization in the allotetraploid Arabidopsis suecica

open access: yesNew Phytologist, EarlyView.
Summary Polyploidization, followed by genome downsizing, is a recurrent evolutionary cycle that dramatically reshapes genome structure. Newly formed polyploids must quickly adjust their cell division machinery to maintain stable chromosome inheritance, while long‐term stabilization involves rediploidization, returning the genome to a diploid‐like state.

Adaptation of the guayule to Mediterranean climate: characterization and enhancement of genetic diversity [PDF]

open access: yes, 2019
The objective of Agroguayule project (co-financing ADEME, Call for projects GRAINE) is to select lines that combine good adaptation to the Mediterranean climate (dry and cold), high vegetative vigour and a high concentration in natural rubber.

Experimental Control and Characterization of Autophagy in Drosophila [PDF]

open access: yes, 2008
Insects such as the fruit fly Drosophila melanogaster, which fundamentally reorganize their body plan during metamorphosis, make extensive use of autophagy for their normal development and physiology.

Current Strategies of Polyploid Plant Genome Sequence Assembly

open access: yesFrontiers in Plant Science, 2018
Polyploidy or duplication of an entire genome occurs in the majority of angiosperms. The understanding of polyploid genomes is important for the improvement of those crops, which humans rely on for sustenance and basic nutrition.

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

open access: yesNew Phytologist, EarlyView.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.

Variation in nuclear genome size in a freshwater snail model system featuring a recent whole-genome duplication

open access: yesRoyal Society Open Science
Conspecifics often share—or are assumed to share—nuclear genome characteristics like nucleotide composition and genome size. These fundamental aspects of the nuclear genome can themselves be the object of natural selection. We here provide the first high-
