“…Targeted efforts are now being made to sequence rare and threatened species of plants as a tool to aid conservation, both in situ [17] and ex situ [18]. This is more urgent among critically endangered species, for which a genome sequence may be all we can retain as the species are lost to extinction.…”

The genome sequence of any organism is key to understanding the biology and utility of that organism. Plants have diverse, complex and sometimes very large nuclear genomes, mitochondrial genomes and much smaller and more highly conserved chloroplast genomes. Plant genome sequences underpin our understanding of plant biology and serve as a key platform for the genetic selection and improvement of crop plants to achieve food security. The development of technology that can capture large volumes of sequence data at low costs and with high accuracy has driven the acceleration of plant genome sequencing advancements. More recently, the development of long read sequencing technology has been a key advance for supporting the accurate sequencing and assembly of chromosome-level plant genomes. This review explored the progress in the sequencing and assembly of plant genomes and the outcomes of plant genome sequencing to date. The outcomes support the conservation of biodiversity, adaptations to climate change and improvements in the sustainability of agriculture, which support food and nutritional security.

“…Volume 31 showcased reviews and syntheses on fish environmental DNA (Yao et al, 2022), metabarcoding in fungi (Tedersoo et al, 2022), in situ conservation of crop relatives' diversity (Wambugu & Henry, 2022), marine phylogeography (Martins et al, 2022), the role of species identity on insect microbiota (Malacrinò, 2022), and how humans affect rates of phenotypic change (Sanderson et al, 2022). These reviews signalled sentiments for a need to discover diversity across diverse taxa and that the conservation of diversity remains a fundamental concern of molecular ecologists.…”

“…These strategies could mitigate the decline of genetic diversity and can provide access to genetic variants better adapted to unprecedented challenges of the current seaweed farming systems. Other con servation strategies that can be applied for eucheu matoids include ex situ conservation such as germplasm banking through culture (De La Fuente et al 2019;Wade et al 2020;Watanabe 2005) and cryopreservation (Yang et al 2021), as well as in situ conservation (Wambugu and Henry 2022). The high number of cultivars in the Philippines makes the region an excellent area for the discovery of new cultivars that can be preserved and their economic potential explored in future crop selection and breed ing programs.…”

Collectively known as eucheumatoids, Eucheuma denticulatum, Kappaphycus alvarezii, K. malesianus, and K. striatus are the main farmed seaweed species in the Philippines. The success of seaweed farming for over five decades in the country is due, in part, to the high diversity of cultivars maintained by the Filipino farmers. Notwithstanding the fact that many eucheumatoid cultivars are presently (and consistently) recognized by the Filipino farmers, there has been no attempt to summarize the current state of the local traditional knowledge about the diversity of this seaweed group, especially with reference to the taxonomy, cultivar designation and distribution. Factors based on present day local knowledge on the eucheumatoid cultivars and what is known on genetic identification in the Philippines were also discussed. A total of 66 cultivars recognized across 58 provinces in the Philippines were documented. Most of these cultivars were morphologically identified as either K. alvarezii or K. striatus, however, the majority were yet to be genetically identified. In part, due to higher demand of kappa-carrageenan extract as compared from the iota type, K. alvarezii and K. striatus were widely cultivated in the Philippines than that of E. denticulatum. Only in the southern Philippines that K. malesianus is currently cultivated. The diverse cultivars identified in this study suggest that the Filipino farmers possess important traditional knowledge that can be useful for future crop selection and breeding.
