Pollen aperture type, shape, size, polar axis length, equatorial P/E ratio, colpus thickness of the sexine and nexine, S/N ornamentation lumen shape width were determined by using light scanning electron microscope. A multivariate analysis was carried out Gover’s general similarity coefficient UPGMA based on 3 qualitative 8 quantitative pollen characters for 43 taxa belonging to 30 genera 19 tr...

Cretaceous massifs of the Eurasian continent is unique not only for its geological features, but also peculiar flora, therefore, identification and study biodiversity these objects currently an urgent task. Comprehensive studies flora vegetation Aktolagay cretaceous massif (Republic Kazakhstan) were carried out in 2019. One aspect was consideration ecological biological features several plant s...

The formation of leaves and other lateral organs in plants depends on the proper specification of adaxial-abaxial (upper-lower) polarity. KANADI1 (KAN1), a member of the GARP family of transcription factors, is a key regulator of abaxial identity, leaf growth, and meristem formation in Arabidopsis thaliana. Here, we demonstrate that the Myb-like domain in KAN1 binds the 6-bp motif GNATA(A/T) an...

As sessile organisms, plants have to continuously adjust growth and development to ever-changing environmental conditions. At the end of the growing season, annual plants induce leaf senescence to reallocate nutrients and energy-rich substances from the leaves to the maturing seeds. Thus, leaf senescence is a means with which to increase reproductive success and is therefore tightly coupled to ...

The TALE homeodomain transcription factor KNOTTED ARABIDOPSIS THALIANA7 (KNAT7) is part of a regulatory network governing the commitment to secondary cell wall biosynthesis of Arabidopsis thaliana, where it contributes to negative regulation of this process. Here, we report that BLH6, a BELL1-LIKE HOMEODOMAIN protein, specifically interacts with KNAT7, and this interaction influences secondary ...
