The early life of terrestrial seed plants often starts under the soil in subterranean darkness. Over time and through adaptation, plants have evolved an el... S Zhong,S Hui,X Chang,... - 《Proceedings of the National Academy of Sciences of the United States of America》 ...
Angiosperm - Seed Structure, Germination, Pollination: Seeds are mature ovules that contain the developing embryo and the nutritive tissue for the seedling. Fruits and seeds are the primary means by which angiosperms are dispersed. The chief agents of di
Aim Natural and human-induced differences in frugivore assemblages can influence the seed dispersal distances of trees. An important issue in seed dispersal systems is to understand whether differences in seed dispersal distances also affect the genetic structure of mature trees. One possible approach ...
SAMPLES have been obtained of seed described as Chinese rape, imported into Europe for oil extraction. The seeds in these commercial samples are either yellow or vinaceous in colour, and the different coloured seeds are to be found in varying proportions. Plants grown from both types of seed c...
A comparison of structure and pattern of the soil seed bank was made between active and stabilized sand dunes in northeastern Inner Mongolia, China. The objective of this paper was to determine the significance of seed bank in vegetation restoration of sand dunes. The results showed that (1) ...
New drugs are urgently needed to combat the global TB epidemic. Targeting simultaneously multiple respiratory enzyme complexes of Mycobacterium tuberculosis is regarded as one of the most effective treatment options to shorten drug administration regimes
1 Few experiments directly test the role of density dependence in natural plant communities. 2 We tested (i) whether different initial seed densities of the entire seed bank of an annual plant community affected performance (emergence, mean plant biomass and survival) and (ii) whether density-dep...
Genetic diversity of oilseed Brassica napus inbred lines based on sequence-related amplified polymorphism and its relation to hybrid performance Significant heterosis for seed yield in oilseed rape has created interest in the development of hybrid cultivars. The DNA-based marker protocol, sequence-r......
Molecular analysis of endo-β-mannanase genes upon seed imbibition suggest a cross-talk between radicle and micropylar endosperm during germination of Arabidopsis thaliana The emergence of embryos from hard seeds is related to the structure of the cell walls of the micropylar endosperm, and not to...
of grain size-related genes have been cloned successfully and functionally dissected (Li et al.2019). The endosperm is the major edible part of rice seed. Therefore, the composition and proportion of endosperm components are the most important determinants of rice quality. In general, the rice ...
