Mapping QTLs for mineral accumulation and shoot dry biomass under different Zn nutritional conditions in Chinese cabbage ( Brassica rapa L. ssp. pekinensis ) [PDF]

, 2008
Chinese cabbage (Brassica rapa L. ssp. pekinensis) is one of the most important vegetables in China. Genetic dissection of leaf mineral accumulation and tolerance to Zn stress is important for the improvement of the nutritional quality of Chinese cabbage

Risks for human health related to the presence of plant lectins in food

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The European Commission asked the European Food Safety Authority (EFSA) to assess the risk related to the presence of plant lectins in food. Based on the available evidence, the CONTAM Panel considered only phytohaemagglutinin (PHA), a legume lectin from beans (Phaseolus sp.), for the risk characterisation.

A new microspore embryogenesis system under low temperature which mimics zygotic embryogenesis initials, expresses auxin and efficiently regenerates doubled-haploid plants in Brassica napus

BMC Plant Biology, 2012
Background Microspore embryogenesis represents a unique system of single cell reprogramming in plants wherein a highly specialized cell, the microspore, by specific stress treatment, switches its fate towards an embryogenesis pathway.

Induction of embryogenesis in Brassica napus microspores produces a callosic subintinal layer and abnormal cell walls with altered levels of callose and cellulose

Frontiers in Plant Science, 2015
The induction of microspore embryogenesis produces dramatic changes in different aspects of the cell physiology and structure. Changes at the cell wall level are among the most intriguing and poorly understood.

Rice panicle temperature and crop microclimate in stressful thermal environments: toward a model of spikelet sterility [PDF]

, 2011
Rice inflorescences are sensitive to chilling and heat, resulting in spikelet sterility. It is not the air temperature itself, however, that causes the stress but the temperature of the sensitive tissues during specific developmental stages.

Semi-thin Sectioning, Light and Fluorescence Microscopy of Floral Bud to Study Microspore Development in Arabidopsis

Bio-Protocol, 2016
Pollen grains are male gametophytes produced within the pollen sacs of the anthers of the flower. Recent genetic studies have revealed several components involved in microspore development (Borg et al., 2009; Berger and Twell, 2011), and yet many ...
