Appendix: Chickpea Research and Root Development
Cytokinin's Role in Root Growth and Drought Tolerance
Cytokinin, a group of phytohormones, plays a crucial role in regulating root elongation and branching during post-embryonic development. Cytokinin-degrading enzymes, known as cytokinin oxidases/dehydrogenases (CKXs), have been utilized to study the biological activities of cytokinin and to engineer root growth. Research has focused on expressing chickpea cytokinin oxidase 6 (CaCKX6) under the control of a chickpea root-specific promoter of CaWRKY31 in Arabidopsis thaliana and chickpea. This was done to investigate the effect of cytokinin depletion on root growth and drought tolerance in both determinate and indeterminate growth patterns.

Experimental Results: Enhanced Root Growth and Drought Tolerance
Root-specific expression of CaCKX6 led to a significant increase in lateral root number and root biomass in Arabidopsis and chickpea. This occurred without any negative impact on the vegetative and reproductive growth of the shoot. Transgenic chickpea lines exhibited increased CKX activity in the root. Advanced chickpea transgenic lines grown in soil demonstrated a higher root-to-shoot biomass ratio and enhanced long-term drought tolerance. Importantly, these chickpea lines were not compromised in root nodulation and nitrogen fixation. The seed yield in some lines was up to 25% higher, with no reduction in protein content. Furthermore, transgenic chickpea seeds possessed higher levels of zinc, iron, potassium, and copper.
Chickpea: An Important Legume Crop
Chickpea (Cicer arietinum L.) is a grain legume with an indeterminate growth habit. It is the second most economically important pulse crop, with a significant annual production. Chickpea is a major protein source for vegetarian populations, particularly in developing countries. Additionally, legumes like chickpea develop a symbiotic relationship with rhizobia, forming root nodules that allow them to acquire fixed nitrogen. This makes chickpea integral to cereal-based intercropping systems as it improves soil fertility. The spatio-temporal regulation of cytokinin is crucial during nodule development, highlighting the importance of investigating whether manipulating root cytokinin levels can be applied to legumes.
Addressing Drought and Improving Chickpea Varieties
Chickpea is often grown in marginal lands with residual moisture, resulting in yields that are far below its potential. Terminal drought severely affects chickpea yield. Therefore, there is a pressing need to develop high-yielding chickpea varieties that can tolerate periodic water-limited conditions and possess higher seed mineral content.
Root Traits and Abiotic Stress
Root traits have been a less-explored area for crop improvement. A direct correlation exists between root size and resistance to water deficit in many crop plants. Plants with larger root systems exhibit an increased ability to compete for nutrients and survive under conditions of nutrient deficiency. The ability of the root system to adjust in response to various abiotic stresses is an important aspect of a plant's performance. Root biomass and the availability of soil resources, including water and minerals, have a strong impact on seed yield.
Root System Architecture and Phytohormones
The root system is highly plastic in its development and adaptation to variable environmental conditions, such as uneven water and nutrient distribution. This plasticity is essential for the acquisition of water and nutrients in a heterogeneous environment. Vertical root growth and root branching, which is the production of lateral roots (LRs), constitute the root system architecture (RSA) of the plant. Various phytohormones, most importantly auxin and cytokinin, play a vital role in root growth and development.
Cytokinin and Lateral Root Formation
In younger root tissues, cytokinin promotes cell differentiation. The mechanism of initiation and elongation of LR is well-studied in Arabidopsis. Local activation of auxin signaling precedes LR primordia formation. Conversely, cytokinin treatment inhibits LR formation. The active cytokinin pool in the plant is regulated by reversible glycosylation, conversion to cytokinin nucleotides by adenine phosphoribosyltransferase genes, and through the irreversible breakdown of cytokinin by cytokinin oxidase/dehydrogenases (CKXs).
CKX Genes and Their Role in Plant Development
The Arabidopsis genome encodes seven CKX genes, some of which have been utilized to study the role of cytokinin in plant development. Overexpression of AtCKX1 resulted in LR primordia formation in close proximity in Arabidopsis due to cell division activity in several pericycle cells (PCs) in a stretch. The seven AtCKX genes display different tissue-specific expression and subcellular localization. AtCKX genes express during LR formation. Grafting of AtCKX1-overexpressing tobacco shoot on wild-type root and vice-versa did not alter the phenotypes of roots and shoots derived from the other plants, indicating that the effect of cytokinin degradation is limited within the CKX1-expressing tissue only. AtCKX3 and AtCKX5 were reported to regulate reproductive meristem activity in Arabidopsis. Expression of AtCKX1 and AtCKX3 under predominantly root-expressing promoters of AtWRKY6 or AtPYK10 caused increased root growth without compromising shoot growth. Tobacco plants expressing AtCKX1 and AtCKX2 in the root showed improved drought tolerance.
Chickpea CKX Genes: Identification and Characterization
A search in the annotated chickpea genome and transcriptome sequences revealed the presence of ten non-redundant genes encoding proteins with sequence similarities to seven Arabidopsis CKX proteins. These were annotated as C. arietinum CKX (CaCKX). Genes encoding two chickpea CaCKX2-like proteins are tandemly repeated in the chickpea genome assembly, likely due to local gene duplication. Similarly, a search identified nine CKX-encoding genes in the annotated Medicago truncatula genome assembly.
Amino acid (aa) sequences of CKX proteins from both legume species and Arabidopsis were aligned to construct a phylogenetic tree. The tree placed two CaCKX6-like proteins and two MtCKX6-like proteins in the same clade with AtCKX6 in close proximity.
CaCKX6: A Detailed Analysis
In order to characterize an unusually long CaCKX6, XP_00451481.1 of chickpea was selected for this study and is referred to as CaCKX6 onwards. The CaCKX6 gene is 4935 bp long with five exons. The protein-coding sequence (CDS) is of 1665 bp encoding a 554 aa long peptide. The CaCKX6 gene expresses the most in the root, more than twofold higher than that in the stem, while expression in the leaf was almost 1.5-fold of that in the stem.
To explore subcellular localization of the CaCKX6 protein, the CaCKX6-YFP construct was agroinfiltrated in Nicotiana benthamiana leaves along with an endoplasmic reticulum (ER) marker and a plasma membrane (PM) marker. Fluorescence overlay analysis and fluorescence intensity scans suggest localization of CaCKX6 in ER. The presence of a punctated structure in the cytoplasm and YFP-labeled ring-like fluorescence of the nuclear envelope around the non-fluorescent nucleoplasm, co-localized with the ER marker, further suggests that CaCKX6 is localized in ER. A minor co-localization of CaCKX6 with the plasma membrane marker was also observed.
Overexpression of CaCKX6: Effects on Root and Shoot Growth
Overexpression of CaCKX6 under the constitutive 35S-CaMV promoter (35S::CKX6) in Arabidopsis resulted in more than a 1.3-fold increase in primary root length and more than a twofold increase in lateral root number when vertically grown in MS media for ten days. The transgenic lines showed better soil-holding capacity when grown in pots for ten days after germination. However, shoots of the pot-grown plants were severely stunted with smaller leaves and delayed reproductive maturity, as observed before in the case of AtCKX1 overexpression.
Root-Specific Expression Using the CaWRKY31 Promoter
Previously, the AtWRKY6 promoter was used to direct root-specific expression of AtCKX1. The chickpea WRKY protein that showed the highest sequence homology with AtWRKY6 has been annotated as CaWRKY31. The promoter of the corresponding gene was used for directing CaCKX6 expression in the root, following transcriptome-based tissue-specific expression analysis. CaWRKY31 expressed primarily in the root of 10-day-old chickpea seedlings, as observed by RT-qPCR.
To investigate the in planta expression pattern of the CaWRKY31 promoter in chickpea, an efficient chickpea transformation protocol was established. A 1500 bp genomic DNA fragment from the CaWRKY31 promoter, including the 5'-upstream activating sequence (5'UAS), was used to direct expression of the reporter protein β-glucuronidase (GUS) to monitor its tissue-specific expression in chickpea. Transformed soil-grown 6-day-old chickpea plants showed expression of the reporter protein activity only in the root (both primary and lateral roots). Transverse sections detected GUS activity in the endodermal layer and in some cells in the conjunctive tissue of the root vascular system.
Phenotypic Analysis of Transgenic Arabidopsis Lines
The CaCKX6 coding sequence (CDS) was inserted under the CaWRKY31 promoter (W31::CaCKX6) to direct root-specific expression of the gene in Arabidopsis. A significant increase in lateral root number was observed in 14-day-old seedlings vertically grown in MS media. Pot-grown transgenic lines showed higher soil-holding capacity and enhanced root network at 14 and 50 days post-germination (dpg) growth stages. Expression of CaCKX6 was confined to the root only.
