Springtime rains can be a surprising source of pollen, according to research supported by the National Science Foundation.University of Iowa researchers report that tree pollen fragments remain in the...
SCR-22 of pollen-dominant S haplotype class is recessive to SCR-44 of pollen-recessive S haplotype class in Brassica rapa
SCR-22 pollen-dominant S haplotype SCR-44 Brassica rapa
2023/8/9
SCR/SP11 encodes the male determinant of recognition specificity of self-incompatibility (SI) in Brassica species and is sporophytically expressed in the anther tapetum. Based on dominance relationshi...
Negative correlations between the susceptibilities of Czech and Slovak pollen beetle populations to lambda-cyhalothrin and chlorpyrifos-ethyl in 2014 and 2015
Meligethes aeneus pyrethroid resistance susceptibility to organophosphates IRAC adult vial tests
2017/4/6
Sixty-five Czech Meligethes populations were tested against lambda-cyhalothrin and chlorpyrifos-ethyl in 2014. In 2015, totally sixty Meligethes populations, some of which sampled also in Slovakia, we...

Doubled haploidy breeding protocols have revolutionized the varietal development programmes in bread wheat, however, the protocols have not proved much efficient in durum wheat. Presently, the durum w...
Scientists discover ancient safety valve linking pollen to bacteria
Scientists ancient safety valve pollen to bacteria
2015/11/12
Like seeds, pollen loses most of its water during maturation, entering a state of suspended animation. This allows it to survive its journey from male to female organs of a flower, where it is rehydra...
