Tea-oil pollen toxic to honeybee larvae: When honeybees forage on the flowers of Camellia oleifera, a widely planted oilseed crop, their larvae die, but what kills the larvae remains controversial. Using bagging and caging studies, the authors show that birds effectively pollinate C. oleifera flowers. In contrast to the hypothesis of nectar toxicity, Zhang et al. (pages 2313-2316) propose that C. oleifera may have evolved toxic pollen to limit overexploitation of its pollen by bees. Toxicity tests indicated that C. oleifera pollen harmed honeybee larvae significantly more than pollen from Brassica napus, another oilseed crop, and C. oleifera pollen contains the insecticidal compound theasaponin. The cover shows simultaneous pollen presentation in a C. oleifera flower.

Why is pollen in Camellia oleifera inedible to honeybees?free

Jannathan Mamut,  Wei-Bing Zhang,  Lu-Lu Tang

This Commentary examines a recent study that addressed a long-standing controversy: Is the lethal effect of Tea-oil Camellia on honeybee larvae due to nectar or pollen toxicity? Flowers of Camellia oleifera are adapting to bird pollination, evolving ‘anti-bee’ traits such as theasaponin-containing pollen, which is toxic to bee larvae.

Exploring pollen chemical defenses in the economically important plant Camellia oleifera and examining their effects on honeybee flower-visiting behavior improves the understanding of the ecological functions of pollen and informs efforts to manage honeybees to bolster C. oleifera production.

Lethal effects of tea-oil Camellia on honeybee larvae due to pollen toxicityfree

Chuan Zhang,  Hui-Hui Feng,  Ya-Lei Liu,  Shuang-Quan Huang

Toxicity tests on tea-oil Camellia flowers (Camellia oleifera) indicated that its pollen harmed honeybee larvae significantly more than pollen from oilseed rape (Brassica napus) flowers. The C. oleifera pollen contained high levels of the toxic triterpenoid theasaponin, which was undetectable in nectar.

OsFAD1OsMYBR22 modulates clustered spikelet through regulating BRD3 in ricefree

Mingxing Cheng,  Huanran Yuan,  Ruihua Wang,  Fengfeng Fan,  Fengfeng Si,  Xiong Luo,  Wei Liu,  Shaoqing Li

The phenotype of rice clustered spikelet mutants results from the upregulation of the FAD/NAD(P)-binding oxidoreductase family gene OsFAD1. Enhanced interaction between OsFAD1 and the transcription factor OsMYBR22 leads to the upregulation of the spikelet clustering-related BR catabolic gene BRD3.

The LpHsfA2-molecular module confers thermotolerance via fine tuning of its transcription in perennial ryegrass (Lolium perenne L.)open

Guangjing Ma,  Zhihao Liu,  Shurui Song,  Jing Gao,  Shujie Liao,  Shilong Cao,  Yan Xie,  Liwen Cao,  Longxing Hu,  Haichun Jing,  Liang Chen

In perennial ryegrass (Lolium perenne), the heat shock factors LpHsfA2/4/5 influence heat tolerance by self-regulating and regulating the expression of the heat-shock protein gene LpHSP18.2 and the ascorbate peroxidase gene LpAPX1. Natural variation in the LpHsfA2 promoter region leads to differences in heat tolerance in perennial ryegrass germplasm.

Tianqi Qiu,  Yuanyuan Su,  Nannan Guo,  Xinyuan Zhang,  Pengfei Jia,  Tonglin Mao,  Xianling Wang

In Arabidopsis, the transcription factor MYB52 represses the expression of ACTIN DEPOLYMERIZING FACTOR9, leading to the decrease of actin filament bundles, thereby regulating pavement cell morphogenesis. In the myb52 mutant, the ACTIN DEPOLYMERIZING FACTOR9 activity is enhanced, promoting pavement cell morphogenesis.

Natural variations in MdNAC18 exert major genetic effect on apple fruit harvest date by regulating ethylene biosynthesis genes

Guo Wen,  Bei Wu,  Yi Wang,  Ting Wu,  Zhenhai Han,  Xinzhong Zhang

Natural variants in the transcription factor gene MdNAC18 affect apple fruit harvest date by modulating ethylene biosynthesis. Two single-nucleotide polymorphisms (SNPs) in MdNAC18, and SNPs and an insertion/deletion in two ethylene biosynthesis genes constitute a genetic variation network and provide an optimized genomics-assisted prediction model for apple breeding.
