The transcription factors and pathways underpinning male reproductive development in Arabidopsis

Frontiers in Plant Science
As Arabidopsis flowers mature, specialized cells within the anthers undergo meiosis, leading to the production of haploid microspores that differentiate into mature pollen grains, each containing two sperm cells for double fertilization.

EFFECTIVENESS OF THE WHEAT Lr22b, Lr34, AND Lr37 GENES FOR ADULT PLANT RESISTANCE TO LEAF RUST IN WEST SIBERIA AND THE CYTOPHYSIOLOGICAL BASIS OF THEIR ACTION

Вавиловский журнал генетики и селекции, 2014
The effect of genes for adult plant resistance to leaf rust has been explored in southern West Siberia by the examples of common wheat cv. Thatcher (Tc), carrying the Lr22b gene, and its near-isogenic lines TcLr34 and TcLr37.
