TL;DR: It is demonstrated that the occurrence of bisexual and hermaphrodite flowers in a PA line is not dependent on CitACS4, but conferred by an unlinked recessive gene which is called pa, which is found in chromosome 1 of watermelon.

Root anatomy and soil resource capture
Jonathan P. Lynch,Christopher F. Strock,Hannah M. Schneider,Jagdeep Singh Sidhu,Ishan Ajmera,Tania Galindo-Castañeda,Stephanie P. Klein,Meredith T. Hanlon +7 more
TL;DR: Evidence that root anatomical phenotypes present opportunities for crop breeding is summarized, including the importance of phenotypic plasticity, integrated phenotypes, C sequestration, in silico modeling, and novel methods to phenotype root anatomy including image analysis tools.

To be a male or a female flower, a question of ethylene in cucurbits.
Cecilia Martínez,Manuel Jamilena +1 more
TL;DR: In this article, the authors survey the new advances in hormonal and genetic control of sex determination in cucurbit species, control which establishes the ethylene biosynthesis and signaling genes as being those that determine the floral meristem towards a male, female or hermaphrodite flower.

Olivier Husson,Jean-Pierre Sarthou,Lydia Bousset,Alain Ratnadass,Hans-Peter Schmidt,John Kempf,Benoit Husson,Sophie Tingry,Jean-Noël Aubertot,Jean-Philippe Deguine,François-Régis Goebel,Jay Ram Lamichhane +11 more
TL;DR: The Eh–pH homeostasis model proposed herein is central to soil and plant health and could become a very powerful tool to develop a “one health approach” unifying a large range of bio-physical processes in a very coherent and consistent manner.

Two centuries of breeding has altered root system architecture of winter wheat
TL;DR: In this paper, the root system architecture (RSA) parameters in a diverse panel of winter wheat released between 1803 and 2002 were measured using GiA Roots software and the results support the idea that plant breeding has had unintended effects on winter wheat root systems, which may have important implications for further breeding work related to nutrient use, drought tolerance, and Csequestration.

The Ethylene Biosynthesis Gene CpACO1A: A New Player in the Regulation of Sex Determination and Female Flower Development in Cucurbita pepo
Gustavo Cebrián,Jessica Iglesias-Moya,J. Romero,Cecilia Martínez,Dolores Garrido,Manuel Jamilena +5 more
TL;DR: A methanesulfonate-generated mutant has been identified in Cucurbita pepo that alters sex determination and reduced ACO1 activity and ethylene production in the different organs where the gene is expressed, and reduced ethylene sensitivity in flowers.

Gene structure and expression characteristics of the auxin receptor TIR1 ortholog in Momordica charantia and developmental analysis of its promoter in transgenic plants
TL;DR: Results indicate that expression of auxin receptor McTIR1 is associated with the pistil development of unisexual flowers in bitter gourd.
Dwarf and deformed flower 1, encoding an F‐box protein, is critical for vegetative and floral development in rice (Oryza sativa L.)
Yuanlin Duan,Shengping Li,Zhiwei Chen,Leilei Zheng,Zhijuan Diao,Yuanchang Zhou,Tao Lan,Huazhong Guan,Runsen Pan,Yongbiao Xue,Weiren Wu +10 more
TL;DR: Describing a recessive mutant dwarf and deformed flower 1-1 in Oryza sativa revealed that DDF1, as a newly identified F-box gene, is a crucial genetic factor with pleiotropic functions for both vegetative growth and floral organ specification in rice.
Involvement of ethylene in sex expression and female flower development in watermelon (Citrullus lanatus).
TL;DR: It is demonstrated that ethylene regulates differentially two sex-related developmental processes: sexual expression, i.e. the earliness and the number of female flowers per plant, and the development of individual floral buds, which runs contrary to findings in other cucurbit species.
Differential Recruitment of WOX Transcription Factors for Lateral Development and Organ Fusion in Petunia and Arabidopsis
TL;DR: It is shown that MAW encodes a member of the WOX (WUSCHEL-related homeobox) transcription factor family and that a partly similar function is redundantly encoded by WOX1 and PRESSED FLOWER in Arabidopsis thaliana, indicating a conserved role for MAW/WOX1/PRS genes in regulating lateral organ development
Minimal structures, generalized topologies, and ascending systems should not be studied without generalized uniformities
TL;DR: In this paper, it was shown that all minimal structures, generalized topologies, and ascending systems can be derived from generalized uniformities, and that they need not be studied separately.
