Plant Biology, Volume 27, Issue 4, Page 549-557, June 2025.Secretion of digestive enzymes in response to prey capture in carnivorous plants with sticky traps is regulated by jasmonates in Drosera capensis but differently by unknown factor in Byblis filifolia. Abstract Carnivorous plants from the order Caryophyllales co‐opted plant phytohormones from a group of jasmonates to regulate digestive enzyme activity ...

The Plant Genome, Volume 18, Issue 1, March 2025.Abstract Wheat breeders are constantly looking for genes and alleles that increase grain yield. One key strategy is finding new genetic resources in the wild and domesticated gene pools of related species with genes affecting grain size. This study explored a natural population of Triticum turgidum (L.) phenotyped for grain weight and size‐related ...

Patterns and Drivers of Pollen Temperature Tolerance
Plant, Cell &Environment, Volume 48, Issue 2, Page 1366-1379, February 2025.ABSTRACT Pollen, a pivotal stage in the plant reproductive cycle, is highly sensitive to temperature fluctuations, impacting seed quality and quantity. While the importance of understanding pollen temperature limits (Tmin, Topt, Tmax – collectively PTLs) is recognized, a comprehensive synthesis of underlying drivers is lacking.

Microsporogenesis and pollen formation in cassava
Biologia Plantarum, 2011 This article describes the complete microsporogenesis and pollen formation in cassava (Manihot esculenta Crantz) at the various developmental stages (pollen mother cell, meiosis, tetrads, early free spore, mid uninucleate, late uninucleate, binucleate ...

Cytoplasniic differentiation during microsporogenesis in higher plants
Acta Societatis Botanicorum Poloniae, 2014 Conspicuous cytoplasmic dedifferentiation in the pollen mother cells takes place early in the meiotic prophase of many plants. This event involves the removal of much of the cytoplasmic RNA.

New Phytologist, Volume 243, Issue 5, Page 1840-1854, September 2024.Summary The B chromosomes exhibit diverse behaviour compared with conventional genetic models. The capacity of the B chromosome either to accumulate or to be eliminated in a tissue‐specific manner is dependent on biological processes related to aberrant cell division(s), but here yet remains compatible with normal development.
