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.

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.

OsALKBH9‐mediated m6A demethylation regulates tapetal PCD and pollen exine accumulation in rice
Plant Biotechnology Journal, Volume 22, Issue 9, Page 2410-2423, September 2024.Summary The N6‐methyladenosine (m6A) mRNA modification is crucial for plant development and stress responses. In rice, the male sterility resulting from the deficiency of OsFIP37, a core component of m6A methyltransferase complex, emphasizes the significant role of m6A in male fertility. m6A is reversible and can be removed by m6A demethylases. However,

International Biological Flora: Ceratonia siliqua
Journal of Ecology, Volume 112, Issue 8, Page 1885-1922, August 2024.The carob tree (Ceratonia siliqua) has a long traditional history in Mediterranean cultures providing food for humans and domestic animals. Its remarkable tolerance of drought, salt and fire, with an ability to thrive in poor, dry soils, makes it ideal for a warming Mediterranean climate.
