Enhancement of developmental defects in the boron‐deficient maize mutant tassel‐less1 by reduced auxin levels

Journal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Plant responses to deficiencies of the micronutrient boron are diverse and go beyond the well‐characterized function of boron in cell wall crosslinking. To explain these phenotypic discrepancies, hypotheses about interactions of boron with various phytohormones have been proposed, particularly auxin.

Honey bee foraging ecology: Season but not landscape diversity shapes the amount and diversity of collected pollen

PLoS ONE, 2017
The availability of pollen in agricultural landscapes is essential for the successful growth and reproduction of honey bee colonies (Apis mellifera L.).

Florigen and Florigen‐Like Genes Regulate Temperature‐Responsive Flowering in Tomato

Advanced Science, EarlyView.
This study uncovers that FLOWERING LOCUS T‐Like 2 (FTL2) and SINGLE‐FLOWER TRUSS (SFT) antagonistically regulate temperature‐responsive flowering in the tomato shoot apical meristem. High temperature induces floral repressor FTL2, which directly inhibits SFT to delay short‐day floral transition, while SFT reciprocally inhibits FTL2 to promote flowering.

Boron deficiency responses in maize (Zea mays L.) roots

Journal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.

The transcription factors and pathways underpinning male reproductive development in Arabidopsis

Frontiers in Plant Science
As Arabidopsis flowers mature, specialized cells within the anthers undergo meiosis, leading to the production of haploid microspores that differentiate into mature pollen grains, each containing two sperm cells for double fertilization.

Applying pollen DNA metabarcoding to the study of plant–pollinator interactions

Applications in Plant Sciences, 2017
Premise of the study: To study pollination networks in a changing environment, we need accurate, high-throughput methods. Previous studies have shown that more highly resolved networks can be constructed by studying pollen loads taken from bees, relative

Spatiotemporal Transcriptomic Atlas Reveals the Regulatory Mechanisms Underlying Early Inflorescence Development and Sex Differentiation in Spinach

Advanced Science, EarlyView.
High‐resolution spatiotemporal transcriptomic data from male and female spinach inflorescences across four key stages first reveal the sex differentiation initiates at the four‐leaf stage and is governed by epigenetic regulation via the SpMSI1‐SpHDT2 complex.

The Arabidopsis KINβγ Subunit of the SnRK1 Complex Regulates Pollen Hydration on the Stigma by Mediating the Level of Reactive Oxygen Species in Pollen. [PDF]

PLoS Genetics, 2016
Pollen-stigma interactions are essential for pollen germination. The highly regulated process of pollen germination includes pollen adhesion, hydration, and germination on the stigma. However, the internal signaling of pollen that regulates pollen-stigma

Variations in the Availability of Pollen Resources Affect Honey Bee Health

PLoS ONE, 2016
Intensive agricultural systems often expose honey bees (Apis mellifera L.) to large temporal variations in the availability (quantity, quality and diversity) of nutritional resources.

Highly Efficient Catalysis of Sulfur Reduction Reaction: 3d10‐Based Catalysts

Advanced Science, EarlyView.
Taking Cu and Zn, two typical 3d10 metal elements, as an entry point, this paper reviews the application of Cu‐based materials, Zn‐based materials and their Cu‐Zn‐based materials in accelerating the sulfur reduction reaction of lithium‐sulfur batteries, which can effectively alleviate the three major problems faced by lithium‐sulfur battery cathodes ...
