Biologia Plantarum, 2011 Sexual polyploidization has both a theoretical as well as an applied significance. Morphological screening for large pollen grains and shape of pollen produced by the individual, cytological investigation of hybrid progeny, and unbalanced separation of ...

Drosophila male genitalia rotation depends on permissive remodeling of the posterior abdomen
Developmental Dynamics, EarlyView.Abstract Background One of the most characteristic morphogenetic processes in Drosophila is the 360° rotation of the male pupal genital disc. This movement is driven by the myosin Myo1D, whose expression in the genital disc is controlled by the Hox gene Abdominal‐B (Abd‐B).

The ecology of polyploid establishment and exclusion, with implications for polyploid biogeography
New PhytologistSummary The relationship between polyploid formation, triploid fitness and plant reproduction has been studied for over a century, and uniparental reproduction has long been recognized to play a crucial role in polyploid establishment.

Polyploidization and epigenetics [PDF]
Chinese Science Bulletin, 2011 The occurrence of polyploidy, or whole genome duplication, can result in instantaneous speciation. Because new polyploids are immediately reproductively isolated from their non-polyploid congeners, polyploidization has played an important role in the diversification of flowering plants and some vertebrates.

Future Postharvest and Food, EarlyView.Processing quality in fruit crops is governed by complex genetic networks controlling texture, sweetness, color, browning, aroma, and nutritional quality. Advances in genomics, genomic selection, and genome editing enable the development of processing‐oriented cultivars with improved industrial performance, reduced postharvest losses, and enhanced ...

Genetic mapping in polyploids [PDF]
, 2018 Many of our most important crop species are polyploid – an unusual phenomenon whereby each chromosome is present in multiple copies (more than the usual two copies).

Circumnutation in the growth of Chara rhizoids
Acta Societatis Botanicorum Poloniae, 2014 The chromosome numbers of 24 species of Achillea L. were determined, among them 4 for the first time (A. chamaemelifolia, A. sulphurea, A. teretifolia, A. vermicularis). A tetraploid form of A. lingulata was found for the first time. The occurrence of di-

Tools for Genetic Studies in Experimental Populations of Polyploids
Frontiers in Plant Science, 2018 Polyploid organisms carry more than two copies of each chromosome, a condition rarely tolerated in animals but which occurs relatively frequently in the plant kingdom.

The epigenetic landscape of plant defense: Unlocking nature's toolkit for new plant protection
New Plant Protection, EarlyView.This review examines how epigenetic mechanisms regulate plant immune gene activation, repression, and priming, then links these natural regulatory layers to emerging epigenetic editing, discussing their potential for precise, heritable crop protection and the challenges.

Haplotype-Based Genotyping in Polyploids
Frontiers in Plant Science, 2018 Accurate identification of polymorphisms from sequence data is crucial to unlocking the potential of high throughput sequencing for genomics. Single nucleotide polymorphisms (SNPs) are difficult to accurately identify in polyploid crops due to the ...
