Pollen Walls as Adaptive Systems
Annals of the Missouri Botanical Garden, 1979 The structural variation of angiosperm pollen is primarily related to the wall, for the male gametophyte itself is simple in organization and more or less uniform in character throughout the group. The division of the wall into an outer exine and an inner intine is clearly a fundamental feature, as it is in the pollen grains and spores of other ...

BcMF26a and BcMF26b Are Duplicated Polygalacturonase Genes with Divergent Expression Patterns and Functions in Pollen Development and Pollen Tube Formation in Brassica campestris. [PDF]
PLoS ONE, 2015 Polygalacturonase (PG) is one of the cell wall hydrolytic enzymes involving in pectin degradation. A comparison of two highly conserved duplicated PG genes, namely, Brassica campestris Male Fertility 26a (BcMF26a) and BcMF26b, revealed the different ...

Tapetal Expression of BnaC.MAGL8.a Causes Male Sterility in Arabidopsis
Frontiers in Plant Science, 2019 Monoacylglycerol lipase (MAGL) hydrolyzes monoacylglycerol, producing free fatty acid and glycerol. Although this enzyme has been shown to play important roles in mammal, its potential function in plants remains poorly understood. In a survey of the MAGL

Defective pollen wall contributes to male sterility in the male sterile line 1355A of cotton
Scientific Reports, 2015 To understand the mechanisms of male sterility in cotton (Gossypium spp.), combined histological, biochemical and transcription analysis using RNA-Seq was carried out in the anther of the single-gene recessive genic male sterility system of male sterile ...

ON REPRODUCTIVE BIOLOGY OF DISTANT HYBRIDS IN THE GROSSULARIACEAE FAMILY
Труды по прикладной ботанике, генетике и селекции, 2018 Pollen morphology and pollen quality in distant hybrids of the genus Ribes L. were studied in the Russian North-West. A rather high fertility level was found in the studied hybrids, except for the triploid ‘Dlinnokistnaya CGL’.
