Life cycle and morphogenetic differentiation in heteromorphic cell types of a cosmopolitan marine microalga. [PDF]
New PhytolSummary Gephyrocapsa huxleyi is a prevalent, bloom‐forming phytoplankton species in the oceans. It exhibits a complex haplodiplontic life cycle, featuring a diploid‐calcified phase, a haploid phase and a third ‘decoupled’ phase produced during viral infection. Decoupled cells display a haploid‐like phenotype, but are diploid.

Leaf transcriptome differences between diploid and tetraploid bahiagrass. [PDF]
Plant GenomeAbstract Polyploid individuals of the subtropical forage grass Paspalum notatum Flüggé (bahiagrass) exhibit distinct phenotypes, including apomixis, enhanced vigor, gigas effects, and increased stress tolerance. While apomixis‐based breeding programs supported by molecular tools have improved agronomic traits such as growth habit, forage dry matter ...

Plants, 2022 Most apomictic plants are facultative, maintaining the ability to reproduce sexually at different frequencies depending on the taxa, ploidy, and reproductive stage.

Notulae Scientia Biologicae, 2021 In this study, aposporic apomictic development and its relation to the different flower development stages were investigated by light and fluorescence microscopy in Crataegus tanacetifolia (Lam.) Pers. (Rosaceae). At pre-anthesis stage, aposporic initial

Crop Science, Volume 63, Issue 6, Page 3382-3392, November/December 2023., 2023 Abstract Cenchrus ciliaris L., a perennial C4 grass, is one of the most widely used forage species in warm and dry regions worldwide. The widespread use of the cultivar Texas raises concerns about genetic homogeneity and vulnerability. Hybridizations among facultative individuals could widen the genic pool. Therefore, a reproductive characterization of

TRIMETHYLGUANOSINE SYNTHASE1 mutations decanalize female germline development in Arabidopsis
New Phytologist, Volume 240, Issue 2, Page 597-612, October 2023., 2023 Summary Here, we report the characterization of a plant RNA methyltransferase, orthologous to yeast trimethylguanosine synthase1 (Tgs1p) and whose downregulation was associated with apomixis in Paspalum grasses. Using phylogenetic analyses and yeast complementation, we determined that land plant genomes all encode a conserved, specific TGS1 protein ...

Red macroalgae in the genomic era
New Phytologist, Volume 240, Issue 2, Page 471-488, October 2023., 2023 Summary Rhodophyta (or red algae) are a diverse and species‐rich group that forms one of three major lineages in the Archaeplastida, a eukaryotic supergroup whose plastids arose from a single primary endosymbiosis. Red algae are united by several features, such as relatively small intron‐poor genomes and a lack of cytoskeletal structures associated ...

Cytogenetics to functional genomics: six decades journey of Professor P.K. Gupta
Plant Biotechnology Journal, Volume 20, Issue 6, Page 1021-1030, June 2022., 2022 Summary We had the fortune of starting our scientific/research careers in the Molecular Biology and Crop Biotechnology Laboratory of Professor P.K. Gupta at Ch. Charan Singh University, Meerut, UP, India. Here, we describe the most important scientific contributions of our beloved mentor in the area of cytotaxonomy, cytogenetics, mutation breeding ...

Molecular Ecology, Volume 30, Issue 11, Page 2659-2675, June 2021., 2021 Abstract Geographical parthenogenesis (GP) describes the phenomenon that apomicts tend to have larger distribution areas and/or occur at higher altitudes or latitudes compared to sexual relatives. However, the complex effects of genome‐wide heterozygosity, ploidy, reproduction mode (sexual vs.

Skipping sex: A nonrecombinant genomic assemblage of complementary reproductive modules
BioEssays, Volume 43, Issue 1, January 2021., 2021 Asexuality arises through developmental alterations with apparently unrelated origins. We show the occurrence of asexual animals and plants have a common genetic and developmental basis on a single nonrecombinant assemblage of genomic elements altering complementary reproductive modules.
