Fertility of Pedicellate Spikelets in Sorghum Is Controlled by a Jasmonic Acid Regulatory Module [PDF]
International Journal of Molecular Sciences, 2019 As in other cereal crops, the panicles of sorghum (Sorghum bicolor (L.) Moench) comprise two types of floral spikelets (grass flowers). Only sessile spikelets (SSs) are capable of producing viable grains, whereas pedicellate spikelets (PSs) cease development after initiation and eventually abort.

Identification of novel QTLs for grain fertility and associated traits to decipher poor grain filling of basal spikelets in dense panicle rice [PDF]
Scientific Reports, 2021 High grain number is positively correlated with grain yield in rice, but it is compromised because of poor filling of basal spikelets in dense panicle bearing numerous spikelets. The phenomenon that turns the basal spikelets of compact panicle sterile in

Exploring Spikelet Fertility and HSP70 Expression as Indicators of High Temperature Tolerance in Rice [PDF]
Discover PlantsAbstract The expression patterns of potential biomarkers can aid in developing thermotolerant rice varieties, addressing food security challenges in times of climate change. This study validated the heat tolerance coefficient and spikelet fertility in rice by linking them to the expression pattern of HSP70. Relative membrane permeability (RMP),

High night temperature induces contrasting responses for spikelet fertility, spikelet tissue temperature, flowering characteristics and grain quality in rice [PDF]
Functional Plant Biology, 2014 Climate change is increasing night temperature (NT) more than day temperature (DT) in rice-growing areas. Effects of combinations of NT (24-35°C) from microsporogenesis to anthesis at one or more DT (30 or 35°C) at anthesis on rice spikelet fertility, temperature within spikelets, flowering pattern, grain weight per panicle, amylose content and gel ...

Responses of spikelet fertility to air, spikelet, and panicle temperatures and vapor pressure deficit in rice [PDF]
Journal of Crop Science and Biotechnology, 2015 High temperature-induced spikelet sterility is expected to become a major factor reducing rice yield under the future climate conditions. To examine the responses of spikelet sterility to air temperature, humidity, and temperatures of panicle and spikelet, two japonica rice cultivars in different maturity groups were exposed to four sets of different ...

THIS1 is a putative lipase that regulates tillering, plant height, and spikelet fertility in rice [PDF]
Journal of Experimental Botany, 2013 Proper branching and successful reproductive growth is of great importance for rice productivity. Substantial progress has been made in uncovering the molecular mechanisms underlying tillering control and spikelet sterility. However, rice tillering is developmentally controlled, and how it is regulated coordinately with reproductive growth remains ...

Spikelet fertility improvement of Boro advanced line (CN6) through supplemented nutrient management
Research in Agriculture Livestock and Fisheries, 2020 The experiment was conducted in the Boro season of 2016-17, at Bangladesh Rice Research Institute (BRRI) farm under the Agro Ecological Zone (AEZ 28) Modhupur Tract. CN6 is a high spikelet bearing early maturing advanced line of rice but low in spikelet fertility. Supplemented nutrient management was examined to increase its spikelet fertility.
