After culturing the anther of a plant, a few diploid plants were got along with haploid plants. Which of the following parts might have given rise to diploid plants? Avegetative cell of pollen Bcells of anther
Azetidina compound, process for its preparation, and a composition for sterilizing the anthers of a plant, a method for producing hybrid seeds and seed hybrid FL FLAzetidine compounds of general formula … … or an acid addition salt thereof, wherein R represents a hydrogen atom or an acyl ...
1A). It consists of two parts: the anther and a supporting filament. The filaments typically serve two roles; they contain the vasculature from the main plant body that terminates within the anther, and filaments elongate (often dramatically) prior to pollen dispersal. Angiosperm anthers have a...
5.And bees help this process along when they touch the anthers of a plant while searching for nectar. 当蜜蜂在寻找花蜜时接触植物的花药时,就会帮助这一过程。机翻 「Life Noggin」 6.An airplane is not clear of runway while the anther is landing or a vehicle occupies the runway. 飞机在花药...

It produces pollen grains through the process of meiosis. What is an anther? Anther definition: a structure located at the top of the stamen (the male reproductive part of a flower) that produces and houses pollen grains. What is the role of anther in plant life? The anther is part of ...

This invention describes novel DNA sequences which function as promoters of anther-specific transcription of coding DNA sequences in recombinant or chimeric DNA sequences. The invention also describes recombinant or chimeric DNA sequences, which are expressed specifically in the anther of a plant. The...
cDNA sequences are disclosed which are expressed specifically in the anther of a plant. Genomic DNA sequences corresponding to the cDNA clones are obtained using the cDNA clones as hybridization probes. Recombinant, or chimeric, DNA sequences are constructed in which the promoter sequence from anthe...
