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...
Rac/Rop GTPases are molecular switches in plants that control the growth of polarized cells such as pollen tubes and root hairs, differentiation, development, actin dynamics, production of reactive ox...
Simulating pollen concentrations with numerical weather prediction (NWP) systems requires a parameterization for pollen emission.
Pollen tube growth, the process that transports the sperm cell to the ovule, is fundamental for plant sexual reproduction. The actin cytoskeleton is essential to the process of pollen tube elongation....
The prevalence of allergic disease is expected to increase with climate change. Grasses, which have highly allergenic pollen, are widely distributed across the globe. Changes in production and allerge...
We did a comparative analysis of pollen and spores from five kinds of natural pollen traps at Wenbi Reservoir, northwest Yunnan, China. The natural traps were the surface soil, ground inhabiting mosse...
Aim of study: Ancient literature alluded to the use of a number of plants/preparations as sex enhancer. One of such botanicals is Phoenix dactylifera in which the pollen grain has been acclaimed to be...
Introduction: Climate change may have an impact of prevalence and severity of respiratory allergies causing changes in the concentrations, distribution, dispersion patterns, and allergenic potential o...
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 ...
