BACKGROUND AND AIMS The polygalacturonase (PG) gene family has been found to be enriched in pollen of several species; however, little is currently known about the function of the PG gene in pollen development. To investigate the exact role that the PG gene has played in pollen development and about this family in general, one putative PG gene, Brassica campestris Male Fertility 9 (BcMF9), was ...

The exine coatings of spores can be used to encapsulate drug molecules. We have demonstrated that these microcapsules can be filled with a commercial gadolinium(III) MRI contrast agent (in this proof of concept study Gd-DTPA-BMA was used) which is slowly released in plasma due to enzymatic digestion of the capsule.

The thermo-sensitive genic male sterility (TGMS) line SP2S is a spontaneous rapeseed mutation with several traits that are favorable for the production of two-line hybrids. To uncover the key cellular events and genetic regulation associated with TGMS expression, a combined study using cytological observation, transcriptome profiling, and gene expression analysis was conducted for SP2S and its ...

Abstract. Saensouk S, P. 2023. Palynology of the genus Lagerstroemia (Lythraceae) in Thailand. Biodiversitas 24: 3222-3229. Pollen morphology from Thailand was poorly reported. This study aimed to pollen 17 species by applying acetolysis under a light microscope and scanning electron microscope. described with distinctive features morphology, i.e., size, shape, exine sculpturing, character aper...

The development of the pollen grain wall in Xiphidium coeruleum (Haemodoraceae) was studied using TEM and cytochemical staining techniques. Microsporocyte ontogeny initiates with the degradation of the cellulosic cell wall and subsequent deposition of a thick callosic cell wall. Following callose deposition, successive meiosis occurs, resulting in a tetragonal tetrad of microspores. during meio...
