The Development of the Pollen of Sarracenia [PDF]
Botanical Gazette, 1908 (WITH PLATE V) During March I907, through the courtesy of Dr. J. M. MACFARLANE, I had the opportunity of gathering material for this study from the fine collection of sarracenias in the greenhouses of the University of Pennsylvania. The species examined were S. fiava, S. purpurea, S. variolaris, S. rubra, and S. psittacina, besides the hybrids S. /lava

Advanced Science, EarlyView.This study shows that BLADE‐ON‐PETIOLE (BOP) proteins regulate floral abscission and senescence in tomato by interacting with TFAM1 to form transcriptional condensates controlling the ARABIDOPSIS THALIANA HOMEOBOX GENE 1 (ATH1)‐mediated abscission pathway.

A Tobacco Homolog of DCN1 is Involved in Cellular Reprogramming and in Developmental Transitions [PDF]
, 2011 Plant proteomes show remarkable plasticity in reaction to environmental challenges and during developmental transitions. Some of this adaptability comes from ubiquitin-mediated protein destruction regulated by cullin-RING E3 ubiquitin ligases (CRLs ...

Coastal permafrost landscape development since the Late Pleistocene in the western Laptev Sea, Siberia [PDF]
, 2011 The palaeoenvironmental development of the western Laptev Sea is understood primarily from investigations of exposed cliffs and surface sediment cores from the shelf.

Development of the Vegetative Cell in the Pollen Grain
CYTOLOGIA, 1970 14 p.-7 fig. In Angiosperms, after meiosis and the formation of microspores, these develop a series of processes leading to maturation. It may be said that one of the first important steps towards maturation is taken when the haploid nucleus undergoes post-meiotic mitosis to give rise to two cells, the vegetative and the generative, which are formed ...

Advanced Science, EarlyView.This study aims to evaluate the impact of the potassium channel KCNJ2 on asthma development. KCNJ2 promotes NLRP3 inflammasome activation through both Ca2+ influx and K+ efflux in airway epithelial cells, which drives allergic airway inflammation and remodeling, suggesting a promising therapeutic target for asthma.

Differentiating apple sports by pollen ultrastructure : a thesis presented in partial fulfilment of the requirements for the degree of Master of Horticultural Science at Massey University [PDF]
, 1995 Cultivars are plants that form distinct, uniform and stable phenotypes. New cultivars can be protected by Plant Variety Rights (PVR) which allow the owner exclusive rights to the propagation and sale of the plant material.

Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction
Advanced Science, EarlyView.During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.

Frontiers in Plant Science, 2017 Cytoplasmic male sterility (CMS) is a maternally inherited trait that results in the production of dysfunctional pollen. Based on reliable reference gene-normalized real-time quantitative PCR (RT-qPCR) data, examining gene expression profile can provide ...
