Increasing evidence suggests that posttranscriptional regulation is a key player in the transition between mature pollen and the progamic phase (from pollination to fertilization). Nonetheless, the ac...
GhGPAT12和GhGPAT25为一对位于陆地棉A12/D12染色体上编码甘油-3-磷酸酰基转移酶(GPAT)的旁系同源基因。GhGPAT12/25在发育早期的花药中特异表达,其转录本主要富集于绒毡层和花粉外壁。真核表达实验表明GhGPAT12/25具有sn-2酰基转移酶活性。CRISPR/Cas9介导的基因敲除实验发现GhGPAT12和GhGPAT25存在功能冗余,两基因的同时敲除导致彻底的雄...
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...
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...
Pollen viability and germinability in some European chestnut genotypes was assessed in this study. In 10 chestnut genotypes, percentages of pollen viability were generally high and often around or ove...
The objective of this study was to determine suitable cultivars to be used as pollinators for 0900 Ziraat. 0900 Ziraat was used as a female cultivar; Bigarreu Gaucher, Bing, Noble, Starks Gold, Stella...
Honey bees and bee products are optimal monitors of the environmental quality; experimental beehives were placed in strategic places of Gran Sasso-Monti della Laga Park. Pollen and honey, produced in ...
The present work analyses the airborne pollen dynamic of the atmosphere of Toledo (central Spain), a World Heritage Site and an important tourist city receiving over 2 millions of visitors every year.
Hourly grass pollen concentrations were recorded over a 10-year study period at an aerobiological station of Badajoz (SW Spain). The record was carried out by means of a Burkard spore trap.
This study investigated the effect of different pH levels on in vitro pollen germination and pollen tube growth in Pistacia palaestina, Pistacia terebinthus, Pistacia atlantica, Pistacia khinjuk, and ...
Mimosa tenuiflora (Willd.) Poir. (Mimosaceae) is a xerophilous plant which is very common in degraded areas in the Brazilian semi-arid region, including areas of beekeeping. The ingestion of leaves fr...
Two field experiments were carried out during the two winter growing seasons of 2007 and 2008 aiming to improve growth, production and pod quality of green bean (Phaseolus vulgaris, L) cv. Pulista us...
Diploid seedless watermelons are presently produced by pollination with partially inactivated (soft X-ray irradiated) pollen. Bud pollination on the day preceding flowering was tested as a means of re...
We investigated paternal contribution in artificial crossed-populations made by mixed pollen from plus tree clones of Cryptomeria japonica D. Don in Niigata Prefecture. Using six polymorphic microsate...
