Frontiers in Plant Science, 2017 Male sterility is important for hybrid seed production. Pollen development is regulated by a complex network. We previously showed that knockout of bHLH142 in rice (Oryza sativa) causes pollen sterility by interrupting tapetal programmed cell death (PCD)

Exploration of Limonium interspecific breeding possibility : a thesis presented in partial fulfilment of the requirement for the degree of Master of Science in Plant Science at Massey University, Palmerston North, New Zealand [PDF]
, 1995 Interspecific crossability was investigated in the genus Limonium (Plumbaginaceae). Six Limonium species were chosen for this study, five of which are dimorphic and L.perigrinum which is monomorphic.

FORMATION OF POLLEN IN THE ANTHER OF LILIUM I. DEVELOPMENT OF THE POLLEN WALL
Acta Botanica Neerlandica, 1980 SUMMARY The ultrastructural changes during the microsporogenesis and gametogenesis in Lilium are studied in relation to the surrounding tissues. In this article the development of the microspore and pollen wall is presented. In relation to the increase in pollen volume the nexine is increased but this process is discontinuous.

Advanced Materials, EarlyView.We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...
