Pollen development in Mill. (Annonaceae). Implications for the evolution of aggregated pollen [PDF]
, 2009 In most flowering plants, pollen is dispersed as monads. However, aggregated pollen shedding in groups of four or more pollen grains has arisen independently several times during angiosperm evolution.

Journal of Integrative Plant Biology, EarlyView.Pentatricopeptide repeat proteins coordinate nucleus‐organelle communication by modulating RNA metabolism within chloroplasts and mitochondria. This review highlights how they control critical processes like photosynthesis, seed development, fertility restoration, and stress survival in crops, and explores their potential as programmable tools for RNA ...

CENH3-GFP: a visual marker for gametophytic and somatic ploidy determination in Arabidopsis thaliana [PDF]
, 2016 Background: The in vivo determination of the cell-specific chromosome number provides a valuable tool in several aspects of plant research. However, current techniques to determine the endosystemic ploidy level do not allow non-destructive, cell-specific

The Organization and Polarity of Pollen Mother Cells of Triticum Aestivum [PDF]
Journal of Cell Science, 1972 ABSTRACT Colchicine has been applied to young developing anthers of Triticum aestivuni at varying stages of maturity from the last premeiotic mitoses of the archesporial and tapetai cells to the second meiotic divisions of the pollen mother cells.

Journal of Integrative Plant Biology, EarlyView.In neo‐tetraploid rice, the NTRF1–SAPK2 heat shock protein–kinase module coordinates abscisic acid signaling with reactive oxygen species homeostasis to ensure timely tapetal programmed cell death and subsequent pollen maturation, providing a resource for the genetic improvement of polyploid rice.

The zinc finger protein DCM1 is required for male meiotic cytokinesis by preserving callose in rice. [PDF]
PLoS Genetics, 2018 Meiotic cytokinesis influences the fertility and ploidy of gametes. However, limited information is available on the genetic control of meiotic cytokinesis in plants. Here, we identified a rice mutant with low male fertility, defective callose in meiosis

New Phytologist, EarlyView.Summary Herbarium specimens are widely distributed in space and time, thereby capturing diverse conditions. We reconstructed specimen ‘lived’ climate from knowledge of germination cues and collection dates for 14 annual species in the Streptanthus (s.l.) clade (Brassicaceae) to ask: which climate attributes best explain specimen phenological stage and ...
