Acetate prevents pistil dysfunction in rice under heat stress by inducing methyl jasmonate and quercetin synthesis [PDF]

Journal of Advanced Research
Introduction: Acetic acid (HAC) is a crucial signal molecule in plant stress responses; however, its role in conferring heat tolerance to rice remains unclear.

Effects of Heat Stress at Vegetative and Reproductive Stages on Spikelet Fertility

Rice Science, 2018
Seed-setting rate, yield components and grain quality traits of 169 accessions from an exotic rice germplasm were tested under high temperatures from 40 °C to 45 °C for 6 h during the daytime at the vegetative and reproductive stages, respectively. The results showed that heat stress significantly decreased the seed-setting rate of all the accessions ...

A Mutation in GIANT CHLOROPLAST Encoding a PARC6 Homolog Affects Spikelet Fertility in Rice [PDF]

Plant and Cell Physiology, 2015
Chloroplasts are not generated de novo but proliferate from a pre-existing population of plastids present in meristematic cells. Chloroplast division is executed by the co-ordinated action of at least two molecular machineries: internal machinery located on the stromal side of the inner envelope membrane and external machinery located on the cytosolic ...

Farmyard manure application increases spikelet fertility and grain yield of lowland rice on phosphorus-deficient and cool-climate conditions in Madagascar highlands [PDF]

Plant Production Science, 2021
Phosphorus (P) deficiency is a major yield constraint for lowland rice production in the tropics. As P-fertilizer resources are finite, alternative fertilizer management is needed for sustainable rice production. We examined whether farmyard manure (FYM),

Induction of Acquired Tolerance Through Gradual Progression of Drought Is the Key for Maintenance of Spikelet Fertility and Yield in Rice Under Semi-irrigated Aerobic Conditions. [PDF]

Front Plant Sci, 2020
Plants have evolved several adaptive mechanisms to cope with water-limited conditions. While most of them are through constitutive traits, certain “acquired tolerance” traits also provide significant improvement in drought adaptation.

Effect of high temperature and water stress on pollen germination and spikelet fertility in rice [PDF]

Environmental and Experimental Botany, 2010
In future climates, rice could more frequently be subjected to simultaneous high temperature and water stress during sensitive developmental stages such as flowering. In this study, five rice genotypes were exposed to high temperature, water stress and combined high temperature and water stress during flowering to quantify their response through ...

Identification of Quantitative Trait Loci for Spikelet Fertility at the Booting Stage in Rice (Oryza sativa L.) under Different Low-Temperature Conditions [PDF]

Agronomy, 2020
Cold stress in rice is a critical factor limiting growth and yield in temperate regions. In this study, we identified quantitative trait loci (QTL) conferring cold tolerance during the booting stage using a recombinant inbred line population derived from

Response of spikelet water status to high temperature and its relationship with heat tolerance in rice

Crop Journal, 2021
In rice, high-temperature stress (HT) during flowering results in decreased grain yield via a reduction in spikelet fertility; however, the effect of plant water status on spikelet fertility under HT remains unknown.

High temperature stress and spikelet fertility in rice (Oryza sativa L.) [PDF]

Journal of Experimental Botany, 2007
In future climates, greater heat tolerance at anthesis will be required in rice. The effect of high temperature at anthesis on spikelet fertility was studied on IR64 (lowland indica) and Azucena (upland japonica) at 29.6 degrees C (control), 33.7 degrees C, and 36.2 degrees C tissue temperatures.
