Less and shrunken pollen 1 (LSP1) encodes a member of the ABC transporter family required for pollen wall development in rice (Oryza sativa L.)

Crop Journal, 2020
Pollen fertility is an agronomic trait that strongly influences rice yield. Recent studies have revealed that the development of the pollen wall is required for pollen fertility and is regulated by several genes. However, the mechanisms underlying pollen

Rice GA3ox1 modulates pollen starch granule accumulation and pollen wall development.

PLoS ONE, 2023
The rice GA biosynthetic gene OsGA3ox1 has been proposed to regulate pollen development through the gametophytic manner, but cellular characterization of its mutant pollen is lacking.

Development of the Vegetative Cell in the Pollen Grain

CYTOLOGIA, 1970
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 with marked ...

The BTB/POZ‐MATH Protein ZmBPM1 Interacts With Autophagy‐related Protein ZmATG6 and Modulates the NLR Protein Rp1‐D21‐Mediated Defense Response in Maize

Advanced Science, EarlyView.
The maize BTB/POZ‐MATH (BPM) protein ZmBPM1 interacts with autophagy‐related protein ZmATG6 to relocate the NLR protein Rp1‐D21 from the nucleo‐cytoplasmic compartment into autophagosome‐like puncta, leading to autophagy‐mediated turnover and suppressing the hypersensitive response.

Voluntary Collective Action to Address Growing Agricultural Challenges in Two Countries: Experimental Insights and Commonalities

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We conducted two framed field economic experiments with citrus farmers in Florida, United States and soybean farmers in Argentina to investigate their willingness to coordinate pest and weed management efforts. Despite the contrast between these two agricultural contexts, we find striking behavioral commonalities.

Advancing European Plant Variety Registration: Data‐Driven Insights and Stakeholder Perspectives

Agribusiness, EarlyView.
ABSTRACT Efficient plant variety registration is crucial for fostering innovation in the European Union, yet the current regulatory framework is complex and faces calls for reform. This study provides data‐driven evidence to inform the ongoing legislative debate by employing a mixed‐methods approach.

THE INFLUENCE OF ELECTROLYTES ON POLLEN TUBE DEVELOPMENT [PDF]

Journal of General Physiology, 1924
These experiments serve to show that neutral salts in amounts considerably below those commonly employed in culture solutions may be very injurious to pollen. It has been found, for example, that NaCl, one of the least toxic salts tried, excepting CaCl2, added to a sucrose solution in a concentration of 0.0002 M, or about 11 parts per million, reduces ...

Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

American Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

POLLUTION AND DEVELOPMENT OF TOMATO POLLEN [PDF]

HortScience, 1992
Air pollution may play a role in gametophytic selection. To estimate whether such selection was occurring, pollen grains from homozygous and heterozygous tomato plants were tested under pollution stress. Homozygous pollen could be expected to respond to pollution more uniformly than heterozygous due to the identical genotype of the
