Avirulence genes of Magnaporthe oryzae are a pathogen defense arsenal shaped by cognate rice resistance genes in the field

New Phytologist, EarlyView.
Population structure and AVR gene presence/absence of 383 single‐spore isolates from the US Mo population. Summary We examined the frequency of and variation in eight avirulence (AVR) genes from 840 Magnaporthe oryzae field isolates collected from the Southern United States relative to rice resistance (R) genes deployed from 1959 to 2017. Little coding

Duckweeds under salt stress: a meta‐analysis of growth inhibition in relation to morphological and physiological traits and a systematic review of molecular responses

New Phytologist, EarlyView.
Salinity reduces duckweed growth responses. Summary Salinity is one of the main environmental factors limiting the performance of duckweeds and despite growing ecological and biotechnological interest in these macrophytes, there is a lack of quantitative analyses of their responses to sodium chloride.

Cold damage to rice during the reproductive stage: a review

Plant Production Science
Yield loss in rice (Oryza sativa L.) caused by low temperatures during the reproductive stage results from the induction of male sterility. This can be critical for rice production in cool climates.

First evidence of Halyomorpha halys (Stål) (Hemiptera Heteroptera, Pentatomidae) feeding on rice (Oryza sativa L.)

, 2017
The brown marmorated stink bug, Halyomorpha halys (Stål) is a pest of numerous annual and perennial crops. Additional distribution records for H. halys are provided from northern Italy where rice is cultivated, and the presence of adults feeding on ...

Climate drivers of mesophyll conductance: temperature and water deficit alter CO2 diffusion and leaf anatomy in cotton

New Phytologist, EarlyView.
Temperature responses of photosynthesis, mesophyll conductance and stomatal conductance to water across Gossypium hirsutum cv Sicot 71, Gossypium arboreum, Gossypium bickii, Gossypium gossypioides and Gossypium sturtianum. Summary Mesophyll conductance (gm) limits CO2 delivery to Rubisco, yet its responses to temperature, heat and water deficit are ...

Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Yield heterosis has been extensively exploited in hybrid breeding, with intersubspecific hybrids often exhibiting the most pronounced effects. However, developing elite hybrids remains a laborious and time‐consuming process. The genetic basis of heterosis has been debated for over a century, hindered largely by the lack of high‐quality genomes.

High‐Contiguity Haplotype‐Resolved Genome Assembly of the Hexaploid Actinidia valvata Rootstock Sheds Light on Waterlogging Resistance Gene

Plant Biotechnology Journal, EarlyView.
ABSTRACT Polyploidisation, creating redundant or diverged copies of the genome, is a major driving force in plant evolution, diversification and environmental adaptation, including for the kiwifruit genus (Actinidia Lindl.). We present a high‐contiguity, haplotype‐resolved genome assembly of the hexaploid Actinidia valvata rootstock cultivar ...

The OsWRKY15‐OsSUT3 Regulatory Module Enhances Rice Pollen Fertility by Mediating Sucrose Allocation to Anthers

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sucrose transport and starch accumulation are crucial carbohydrate metabolic processes in rice, playing essential roles during late pollen development to ensure pollen maturation, fertility and high grain production. However, the molecular mechanisms regulating sucrose transport and starch accumulation during rice pollen development remain ...

RICE (ORYZA SATIVA L.) ANDROGENESIS IN VITRO

Experimental biology
Rice (Oryza sativa L.) is a cereal crop cultivated mainly in tropical and even some subtropical countries and provides food for more than half of the world's population. Nowadays, haploid biotechnology (gynogenesis and androgenesis) is used in breeding practice as one of the tools to improve rice, preferably in vitro androgenesis.

Metabolic Rewiring of the Shikimate Pathway Enables Rose‐Scented Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Rice fragrance is a key determinant of grain quality, yet the aroma profile of cultivated rice is highly uniform and largely dominated by the popcorn‐like compound 2‐acetyl‐1‐pyrroline. Here we expanded the aromatic repertoire of rice by engineering a rose‐like fragrance through reconstruction of the phenylalanine‐derived 2‐phenylethanol (2‐PE)
