Mapping a Partial Andromonoecy Locus in Citrullus lanatus Using BSA-Seq and GWAS Approaches

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.

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.

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.

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.

TL;DR: The Cldw-1 gene was primary-mapped onto watermelon chromosome 9 by next-generation sequencing-aided bulked-segregant analysis of F2 plants derived from a cross between a normal-height line, WT4, and a dwarf line, WM102, in watermelon, and the candidate region identified was validated and confirmed by linkage analysis using 30 simple sequence repeat (SSR) markers in an F2 population of 124 plants.

TL;DR: Evidence is provided for a role of TCP8 in flowering control and knowledge of the molecular basis ofTCP8 function is added, as TCP8 overexpression in the flc-6 loss-of-function mutant failed to delay flowering.

TL;DR: QTL analysis of multiple populations in multiple environments revealed that the fsd6.2 locus, which includes the candidate gene Csgl3, controls high fruit spine density in natural cucumbers, and evolved during cucumber domestication.

TL;DR: The QTL and candidate genes identified in the present study lay the foundation for marker-assisted selection for sex expression traits in watermelon.
