Transcriptomic Analysis of the Highly Heterotic Maize Hybrid Zhengdan 958 and Its Parents During Spikelet and Floscule Differentiation

Journal of Integrative Agriculture, 2012
Heterosis plays an important role in crop production and plant evolution. Although heterosis has been widely exploited by plant breeders, the underlying molecular mechanisms are not well understood.

Quantitative trait locus analysis for spikelet shape-related traits in wild wheat progenitor Aegilops tauschii: Implications for intraspecific diversification and subspecies differentiation. [PDF]

PLoS ONE, 2017
Wild diploid wheat Aegilops tauschii, the D-genome progenitor of common wheat, carries large genetic variation in spikelet and grain morphology. Two differentiated subspecies of Ae.

Effects of genes increasing the number of spikelets per panicle, TAW1 and APO1, on yield and yield-related traits in rice

Plant Production Science, 2017
The genes TAWAWA1 (TAW1) and ABERRANT PANICLE ORGANIZATION1 (APO1) increase the number of spikelets per panicle (SN). In the present study, we examined the effects of these genes on morphological traits, yield, and yield-related traits including yield ...

Inheritance Of Spikelet Fertilty in two Rice Crosses [PDF]

, 2007
Spikelet sterility is the greatest barrier to rice hybridization. Two crosses IDSA 85/NERICA 1 and IDSA 85/JASMINE 85 were made to study the inheritance of spikelet fertility.

SUPER WOMAN 2 (SPW2) maintains organ identity in spikelets by inhibiting the expression of floral homeotic genes OsMADS3, OsMADS58, OsMADS13, and DROOPING LEAF

Journal of Integrative Agriculture
Flower organ identity in rice is mainly determined by the A-, B-, C- and E-class genes, with the majority encoding MADS-box transcription factors. However, few studies have investigated how the expression of these floral organ identity genes is regulated

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Genetic association of spikelet abortion with spike, grain, and shoot traits in highly-diverse six-rowed barley

Frontiers in Plant Science, 2022
Spikelet abortion is a phenomenon where apical spikelet primordia on an immature spike abort. Regardless of the row-type, both apical and basal spikelet abortion occurs, and their extent decides the number of grain-bearing spikelets retained on the spike—

Understanding spikelet orientation in Paniceae (Poaceae)

American Journal of Botany, 2010
Spikelet structure and grouping are key characters to identify grasses. Here we tested the possibility that spikelet pairs, a distinctive morphological structure of many Andropogoneae and Paniceae, are the starting point for a secondary single spikelet condition that can also explain the change of spikelet orientation among Paniceae genera.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
